I'm binging on your old video's. I'm here 4 yrs later and the advice is still gold! The sad thing is I'm here 4 years after the video and that old engine is a heck of a lot newer than my engine is today. I'm running a 1987 Merc BM 150. I rode old two stroke dirt bikes and have always had two strokes in my life. I love two stroke engines and the thought of a V6 two stroke engine is just awesome to me. Then when you here it fire up and that 2 stroke growl comes out ❤❤. As you know down here in Florida we don't really have to worry about cold starts to much and thats usually when a two stroke is a hassle to bring to life. Down here it's heat that you have to worry about. This old Merc runs hot even when the cooling system is working 100 % it's not hard to cook the electrical components in it idling or slow speed trolling or running it to hard for to long. Two strokes with this much displacement and being air cooled need to have consideration of temperature at all times and may require down time for cooling. That's one of the things you have to deal with if you want that raw power of a two stroke.

Late comment but I just had to do this to a 60hp Suzuki that had been sitting for 7 years, owned by my daughter'sboyfriend. I should have searched for this video beforehand. The vst was filled with stale fuel so bad that it was like molasses and had buggered the hp pump. It eventually went with a new pump and a complete fuel system flush including injectors. One important step is also to drop the leg and inspect or replace the water pump or even just the impeller. I replaced this one but also had to flush the cooling system to get it to pump water. I thought your step of spraying the cylinders with oil was a really good idea but, like I said, I didn't search for this video before I did the job. Thanks again for the great video and all your other videos. There are plenty of us out here that really appreciate that you take the time to post them, and hopefully you get some time to boat and fish too.
I have a two stroke Yamaha that sat for over seven years. I did run it out of fuel and emptied the carbs. Dumped new fuel and batteries when I went to crank it up. It was unbelievable it fired up and is still running today.
Can you turn the injector? I use a long needle nose pliers with the curved end and that seems to get the injectors out by using the pliers as a prying motion. I also give it a spray of silicon lube.
Yeah, that night do it. It got late and I didn't want to break them. I have some double jointed needle noses with a bend in the end. I'll give it a try this week, the other injectors are clean and operating properly :) thanks for the advice!

Also when you were starting the engine; were you running it off that 5 gallon external fuel tank? Is this okay to do without a fuel pump inline?
You would just take the drains off the carb bowls and then yes, squeeze the primer bulb to push the clean fuel in, yes, was running off the 5 gallon tank :) the engines got the fuel pump on it.
@@BornAgainBoating do I need to worry about clogged jets after two years of the engine sitting?

Hello I have a a 2004 Yamaha two-stroke 150 I start the engine with no problem the engine run fine no problem but when I turn the engine off and after 2 or 3 hours I try to turn the engine but crank and won’t start. It starts after a while Do you have any troubleshooting videos for this?
Should of replaced the vst filters no matter what. Fuel water separator primer ball and all fuel lines from tank to engine and the check valve. If you lean out a two stroke just once you could cause pre detonation and cost a customer an engine
I have a 2004 200 Yamaha hpdi and are having to do the work myself. Question, would it be easier to replace with cheap ones instead of cleaning them, the injectors
Compare the cost of cleaning the injectors versus replacing them with new ones. Sometimes, cleaning can be more cost-effective, especially if the injectors are not severely damaged and vice versa.
Based on you experience , do you see a particular brand with more issues/problems with their outboard than the others? There is any brand better than the others on the market today ? Im talking about reliability .. i love yamas , in particular the v6 range because they arent too heavy and have a good power but even with the range that i consider the best inside yama , they are known for problems with their lowers and the vst
Umm, to be honest, most of the big companies right now, when buying new, are making pretty reliable engines. Mercury's new V-6 or V-8 are still extremely new to say anything about, but I would say to stick with a Yami, Merc, or a Suzuki. Evinrudes don't seem to be as caught up with the rest of the industry. There are people that swear by their E-TEC's but then the other 50% of E-TEC owner's hate them. I know our FWC down here blew up 7 E-TECS in one year, they shortly after took every single one off of their boats...
Hello, great video. I have a 1999 Yamaha 200hp that is on a stand. I don't have the ignition cable or switch. Can you possibly tell me how I can start this motor with out it or get a rig like yours? Any help would be appreciated, thank you.
Hello, thank you for your support! I've never tried to jump a harness and then jump the starter to start a Yamaha engine without the keyswitch. It might be possible. I'll have to look up the wiring diagram to see what wires need to be jumped and if it is possible. You will need to hook a battery to it and then if the harness can be jumped at the plug, you'll just take a screw driver and jump the starter. email me at aaron@bornagainboating.com so this comment doesn't get burried and I don't see the replies.
I have a 2002 hpdi 200hp. Can you clean that cloudy stuff out of the fuel tank without removing the tank as i dont want to cut up the floor to get it . The fuel is no where as bad as that 300 its just a little bit cloudy . will the fuel filters water traps stop it going into the injectors it is running awesome for now
Depends on how old the fuel is, the water separators should catch any kind of debris or water before it gets to the engine. There are companies that polish fuel and fuel tanks, but that depends how bad it is. If the engine is running great and you just have some really old fuel. Just unhook the fuel line from the primer bulb and put a cheap fuel pump from napa or advanced auto and pump the old stuff out and get rid of it. Then just fill up with some fresh ethanol free blend and put some ring free in the tank. That'll be fine. Otherwise if the fuel isn't that bad, put some ring free in it and go out and burn it all up! Then fill up with some fresh fuel :)
Thanks for your reply i will give this a try fuel abut 5 months old and fiberglass tank so i have never run ethanol i have used premium as its the only ethanol free fuel bp sell and its along way between gas stations wherei am now i am back to normal unleaded avoiding bp fuel all together
As long as there isn't anything wrong with the fiberglass tank, you shouldn't have trouble there. 5 month old ethanol fuel shouldn't be that bad. The HPDI should burn that without an issue. Try to burn it up quick though, it's in the stage now of slowly loosing it's octane.
I recently purchased an E-Tec 225 that has been sitting for about 10 years unfortunately they added fresh gas and oil and ran it and didn't clean the fuel system before starting. Now my injectors are clogged and are out for cleaning. What would you guys recommend as a fuel treatment to keep them from clogging up again
Oh man, that's a bummer :( hopefully they get back in soon! You can just run some Quickleen or some Ring Free occasionally with your fuel fill ups. That should keep the injectors pretty clean! Both of those products are really good!
No! Don't do that! You can destroy the engine doing that! The HPDI isn't like an old carbureted two stroke that you could do that with, you can't take off the oul systems on direct injected engines :( so hpdis and optis you don't want to do that! Sorry
I really messed up with my Yamaha 50hp it sat for 4 years and I just tried to start it never started tested compression and they are around 80-100psi any tips on how to regain the compression?
You should try and get it running to see if compression will come up. It should still run with 80 psi compression. Also make sure that the pistons don't have any play in them
how much do you think all that work would cost? I might be getting a boat that has been garaged since 2004 with an Outboard motor. Just trying to get a feel for how much I will need to get it running again.
You might be looking at a little different process being 15 years! The good thing is that it was kept in a garage. Where are you located? Seeing a boat was put in a garage for and kept there for 15 years, I would say it is likely that the engine was flushed and fogged before storing it and so you might have very little work that needs done to it :) Maybe just pumping out the old gas and filling up the tank with new gas. Changing out the fuel filters and maybe a set of plugs. What kind of engine is it? Most mechanics charge around $100 an hour and shops (In the keys) are around $140 and hour. If it is a good situation being in the garage and taken care of. It might only be 2-3 hours of work so you could get away with a couple hundred bucks! Worst case scenario is that it take a couple of days so lets say 16 hours of work. You are looking at about $1600 dollars plus parts. Let me know more about the situation and I could probably give you a better and closer number!
@@BornAgainBoating its an outboard motor. redding.craigslist.org/boa/d/medford-1994-seaswirl-striper-cuddy/6883784398.html Trying to link see if it works, located in medford OR.
@rymaal Sorry, this comment got buried and I missed the notification! That looks like a really clean boat. Being up there in OR you probably won't see any of the corrosive issues that we see down here. That engine will probably fire right up, I would just go through the steps as in the video. Just drain the carbs and then put fresh fuel in them. Most likely with that engine, you are probably looking at cleaning out the carbs and then putting a set of spark plugs in it! You might even get away with not having to clean out the carbs though! If you do, it should only take a couple of hours to clean and put back together, if nothing breaks or is not messed up. Judging by the way the boat looks, the engine is probably in really good shape!
Hey man I wish if you could help me please, I have a honda 225hp, it misfires on 2 cylinders, I checked for spark while having a new coil and plug and everything is fine, a even changed the coils from working cylinders and the problem does not shift.

Hey!!! I got a 2001 Mercury 225 optimax that last monday when I was going out for some fishing and I forgot to put the bottom plug the one in the bottom cover and the engine breathed in all the water through the admission. Engine now starts but wount accelerate more than 2000 rpm. what do you think about it?
Just some regular old fogging oil. You can use anything, just to get them lubed up before moving the springs. WD-40, PB blaster, whatever you have handy will work.
@@BornAgainBoatingFYI WD40 is not exactly a long-term lubricant - it is a water displacement fluid. The WD will get things unstuck, but it will not seriously lubricate.
great video, just joined you channel. question, merc 90 hp 2001, 4 carb's. 1 carb no fuel coming out of bowl, cylinder not getting fuel. any ideas on freeing up the debris in it WITHOUT removing the carb's? engine runs on 3 cylinders, compression is good, all on new gas and filter, spark verified strong and ok. can we start it and put carb cleaner in the throttle area of the bad carb? any other suggestions?
Thank you! You can try and disconnect the fuel line to that carb and put some powertune into the line and then run the engine hard. That might work, but it would be a lot easier, quicker, and better to just take the carbs off and clean them :)
@@BornAgainBoating Really enjoyed your video, curious if carb cleaner is the same thing as powertune or because it is a mercury you are recommending a mercury product just to be on safe side. i support manufacture products
@@BornAgainBoating Hi, may i ask why removing the float bowl screw on any of the 4 carbs doesn't pour out fuel "at idle"? Lastly i know dumb question but on the carb in question is there not a way to somehow put a 90 degree pick wire up and actuate the float that could be stuck? I agree carb removal would be real nice, there are some very difficult intake manifold bolts that look impossible to get to on the bottom, i would love to try the job but i don't have anyone to ask when i get to that bolt how to remove it.
Whenever you take the drain screw out, fuel should come out of the bowls. If not, they are either clogged or there is no fuel in them. I don't know of anyway to stick something in the carb without removing it. You're bolt shouldn't be that difficult. Just a swivel socket should do the trick. Probably have to split the side chaps if that is possible. That should get you more room. Is this a carbuerated 4-stroke?
Yup, this is basic to all outboards. You are basically going over all the vitals of the engine and making sure you aren't pushing bad fuel into the engine's fuel system. Those old Johnson's though you are going to be draining the carbs and you might have to clean the carbs, depending on the situation.
I have a Yamaha 90 that keeps shutting down after running at top in for 40 seconds under load. Does anyone know what it might be. Carburetors have been rebuilt by my mechanic and it’s still doing this.
Still sounds like a fuel issue, the carbs could be worn out or the lift pumps are pumping enough fuel. You could open up the lift pumps and check them out
Just some engine fogging oil is fine, just to get things lubed before running the engine :) Starbrite Fogging Oil, or CRC Fogging oil, I don't think the brand is as important as just getting some sort of oil in the cylinders
Besides flushing it with the flush port, what should a person do if they completely cloged a verado 350 with sand, overheated it, immediately shut it down and started it and stoped it a few times until water flowed again? (Asking for a friend) are there any places that need to be cleaned out like the water strainer etc? Thank you.
Hello! It happens, they aren't the first person to do that :) If it's peeing then the water pump impeller is still working fine. It would be good to pull the thermostat and back flush it, clean out the thermostat housing, and then you should be fine. Depending on how mechanical they are, it wouldn't be a bad idea to drop the lower unit and clean off the water pump housing. Depending on when the last oil change was. You can clean out a 5 gallon bucket and then reuse the oil if it is pretty fresh. Just make sure that the oil drain plug seal gets replaced, don't unscrew it and then put it back in without replacing. It's basically a smash seal, so once it's been smashed, the seal never seals up properly again. It might hold for awhile, but then could leak without you knowing it and possibly run low on oil while out and about! Here's some videos that could help get you in the right direction: th-cam.com/video/oKV3-n5v59o/w-d-xo.html Lower Unit Impeller Replacement: th-cam.com/video/YtivxsdwEqY/w-d-xo.html
Thanks very much. From my flow diagram it looks like only smaller components receive strained raw water while the block etc get it all. The thermostat was clean but I should have backfushed from there in hindsight. Seems like everything under the cowling has water running through it... I will do as told. I already replaced the water pump as I lost a few psi at idle in the weeks that followed. Great channel. GB
Bench cleaning Yamaha fuel injectors is a waste of time and your money. Ship them to Yamaha and they will clean them professionally otherwise the injectors will gum up soon again.
Yamaha doesn't clean injectors. They sell new ones. But there are companies that will clean them and flow them for you. Flagship is one of the major companies in Florida.
Oh yeah, this thing was pretty nasty. It has been sitting for over 6 years that I know of! I got three of the injectors cleaned yesterday. Now I need to clean out the injectors that wouldn't come out. :( Hopefully it is just the injectors and it's not something wrong with the high pressure pump. This engine isn't worth putting that kind of money into!
"VST" What a hell is that? If you are doing a tutorial video, do you think you can pronounce full words for general public/ no mechanics ( which I suppose know how ro do that job) understanding?
The VST is the vapor separator tank. It is similar to the FSM or fuel supply module on Mercury outboards. We wrote an article about it, link is here if you are interested www.bornagainboating.com/what-is-an-outboard-fsm-or-vst/

It is alright to run the motor on the flush hose? I thought you had to use muffs on yammies.
Yes, you just don't want to rev the engine up on the flush port. But just running it at idle is fine for a minute or two.
Good job Bluetooth
You wouldnt happen to have a video on replacing the screens in the high pressure pump do you?

@@BornAgainBoating I meant the belt driven high pressure pump for an hpdi, thank you anyways!
Dear sir. Can you please teach me how actuat DTS with diagnostic soft wear.

You've gotta have the software and then just follow the instructions :)
Based on you experience , do you see a particular brand with more issues/problems with their outboard than the others? There is any brand better than the others on the market today ? Im talking about reliability .. i love yamas , in particular the v6 range because they arent too heavy and have a good power but even with the range that i consider the best inside yama , they are known for problems with their lowers and the vst
Umm, to be honest, most of the big companies right now, when buying new, are making pretty reliable engines. Mercury's new V-6 or V-8 are still extremely new to say anything about, but I would say to stick with a Yami, Merc, or a Suzuki. Evinrudes don't seem to be as caught up with the rest of the industry. There are people that swear by their E-TEC's but then the other 50% of E-TEC owner's hate them. I know our FWC down here blew up 7 E-TECS in one year, they shortly after took every single one off of their boats...
Hello, great video. I have a 1999 Yamaha 200hp that is on a stand. I don't have the ignition cable or switch. Can you possibly tell me how I can start this motor with out it or get a rig like yours? Any help would be appreciated, thank you.
Hello, thank you for your support! I've never tried to jump a harness and then jump the starter to start a Yamaha engine without the keyswitch. It might be possible. I'll have to look up the wiring diagram to see what wires need to be jumped and if it is possible. You will need to hook a battery to it and then if the harness can be jumped at the plug, you'll just take a screw driver and jump the starter. email me at aaron@bornagainboating.com so this comment doesn't get burried and I don't see the replies.
I have a 2002 hpdi 200hp. Can you clean that cloudy stuff out of the fuel tank without removing the tank as i dont want to cut up the floor to get it . The fuel is no where as bad as that 300 its just a little bit cloudy . will the fuel filters water traps stop it going into the injectors it is running awesome for now
Depends on how old the fuel is, the water separators should catch any kind of debris or water before it gets to the engine. There are companies that polish fuel and fuel tanks, but that depends how bad it is. If the engine is running great and you just have some really old fuel. Just unhook the fuel line from the primer bulb and put a cheap fuel pump from napa or advanced auto and pump the old stuff out and get rid of it. Then just fill up with some fresh ethanol free blend and put some ring free in the tank. That'll be fine.
Otherwise if the fuel isn't that bad, put some ring free in it and go out and burn it all up! Then fill up with some fresh fuel :)
Thanks for your reply i will give this a try fuel abut 5 months old and fiberglass tank so i have never run ethanol i have used premium as its the only ethanol free fuel bp sell and its along way between gas stations wherei am now i am back to normal unleaded avoiding bp fuel all together
As long as there isn't anything wrong with the fiberglass tank, you shouldn't have trouble there. 5 month old ethanol fuel shouldn't be that bad. The HPDI should burn that without an issue. Try to burn it up quick though, it's in the stage now of slowly loosing it's octane.
IF YOU ARE GOING TO GET A FOLLOWING YOU GOTTA BE CONSISTENT ! WHERE IS THE 2ND PART OF STARTING THE OLD YAMAHA ????????
I'm getting ready to do a 1978 Evinrude 150 base.
Awesome! Now that's some antique work there :) That is a different line of work :)
Just got my old 79 140 going again. Cold starts faster than my 2017 truck
I recently purchased an E-Tec 225 that has been sitting for about 10 years unfortunately they added fresh gas and oil and ran it and didn't clean the fuel system before starting. Now my injectors are clogged and are out for cleaning. What would you guys recommend as a fuel treatment to keep them from clogging up again
Oh man, that's a bummer :( hopefully they get back in soon! You can just run some Quickleen or some Ring Free occasionally with your fuel fill ups. That should keep the injectors pretty clean! Both of those products are really good!
A really good water separating filter and a new Merc...
I have a pair of 2005 yahama hpdi 200 can I disconnect the oil pump and mix the oil with gas myself? What's the best thing to do?
No! Don't do that! You can destroy the engine doing that! The HPDI isn't like an old carbureted two stroke that you could do that with, you can't take off the oul systems on direct injected engines :( so hpdis and optis you don't want to do that! Sorry
@@BornAgainBoating thank you so so so much
Aerokroil is the bomb 👍
Yes it is!
What does this kind of service typically run?
I really messed up with my Yamaha 50hp it sat for 4 years and I just tried to start it never started tested compression and they are around 80-100psi any tips on how to regain the compression?
You should try and get it running to see if compression will come up. It should still run with 80 psi compression. Also make sure that the pistons don't have any play in them
Born Again Boating would you be able to work on the engine? I am in Jupiter Florida not sure where your business is located.
What’s the name of the piece that the tubings is connected to for the cables
Umm are you talking about the rigging grommet or the control cable ends?
how much do you think all that work would cost? I might be getting a boat that has been garaged since 2004 with an Outboard motor. Just trying to get a feel for how much I will need to get it running again.
You might be looking at a little different process being 15 years! The good thing is that it was kept in a garage. Where are you located? Seeing a boat was put in a garage for and kept there for 15 years, I would say it is likely that the engine was flushed and fogged before storing it and so you might have very little work that needs done to it :)
Maybe just pumping out the old gas and filling up the tank with new gas. Changing out the fuel filters and maybe a set of plugs. What kind of engine is it?
Most mechanics charge around $100 an hour and shops (In the keys) are around $140 and hour. If it is a good situation being in the garage and taken care of. It might only be 2-3 hours of work so you could get away with a couple hundred bucks!
Worst case scenario is that it take a couple of days so lets say 16 hours of work. You are looking at about $1600 dollars plus parts.
Let me know more about the situation and I could probably give you a better and closer number!
@@BornAgainBoating its an outboard motor. redding.craigslist.org/boa/d/medford-1994-seaswirl-striper-cuddy/6883784398.html Trying to link see if it works, located in medford OR.
@rymaal Sorry, this comment got buried and I missed the notification! That looks like a really clean boat. Being up there in OR you probably won't see any of the corrosive issues that we see down here. That engine will probably fire right up, I would just go through the steps as in the video. Just drain the carbs and then put fresh fuel in them. Most likely with that engine, you are probably looking at cleaning out the carbs and then putting a set of spark plugs in it!
You might even get away with not having to clean out the carbs though! If you do, it should only take a couple of hours to clean and put back together, if nothing breaks or is not messed up. Judging by the way the boat looks, the engine is probably in really good shape!
Hey man I wish if you could help me please, I have a honda 225hp, it misfires on 2 cylinders, I checked for spark while having a new coil and plug and everything is fine, a even changed the coils from working cylinders and the problem does not shift. I have checked for fuel and fuel is spraying nicely out of the injectors. Checked for compression and I have 175psi on I'll cylinders. I'm lost, if you could help will be greatly appreciated
Hell ya boats and stuff!!
As the boating world comes alive in Chicago when do the tubes come out!?!?!
@@BornAgainBoating once you get past the body parts floating trash the water here can be a great place to spend the weekend!! But dont forget kids dont take your shoes off or get any in your mouth!!
@@dr650lytle hahha yeah, something about drinking brown water, just doesn't sound appealing! :)
Hey!!! I got a 2001 Mercury 225 optimax that last monday when I was going out for some fishing and I forgot to put the bottom plug the one in the bottom cover and the engine breathed in all the water through the admission. Engine now starts but wount accelerate more than 2000 rpm. what do you think about it?
Well, thats not good. You'll need to pull the plugs and check em out, and take a look at our opti video and run those tests :)
Born Again Boating I will bro. thank you. a actually watshing all of your videos
thank you
Great channel. Keep it up.
Would love to see a video on checking compression and things to look for when purchasing a used boat or motor.
Disregard i jumped the gun and posted before watching the video. HA
I think this could have been a good engine for the Toyota supra mark V
They are really similar to some of Toyota's engines :)
What type of oil did you used on throttle plates?
Just some regular old fogging oil. You can use anything, just to get them lubed up before moving the springs. WD-40, PB blaster, whatever you have handy will work.
@@BornAgainBoatingFYI WD40 is not exactly a long-term lubricant - it is a water displacement fluid. The WD will get things unstuck, but it will not seriously lubricate.
wish i could lift my suzuki cowling like that....no handles and nut buster heavy!
Haha they aren't that bad! Lol cool channel by the way! We just subbed :)
@@BornAgainBoating me too....yeah, unlike a Honda I could take that off with one hand!
great video, just joined you channel. question, merc 90 hp 2001, 4 carb's. 1 carb no fuel coming out of bowl, cylinder not getting fuel. any ideas on freeing up the debris in it WITHOUT removing the carb's? engine runs on 3 cylinders, compression is good, all on new gas and filter, spark verified strong and ok. can we start it and put carb cleaner in the throttle area of the bad carb? any other suggestions?
Thank you! You can try and disconnect the fuel line to that carb and put some powertune into the line and then run the engine hard. That might work, but it would be a lot easier, quicker, and better to just take the carbs off and clean them :)
@@BornAgainBoating Really enjoyed your video, curious if carb cleaner is the same thing as powertune or because it is a mercury you are recommending a mercury product just to be on safe side. i support manufacture products
Yeah, carb cleaner will work, that's fine. I really think you are going to have to take the carbs off and clean them though :)
@@BornAgainBoating Hi, may i ask why removing the float bowl screw on any of the 4 carbs doesn't pour out fuel "at idle"? Lastly i know dumb question but on the carb in question is there not a way to somehow put a 90 degree pick wire up and actuate the float that could be stuck? I agree carb removal would be real nice, there are some very difficult intake manifold bolts that look impossible to get to on the bottom, i would love to try the job but i don't have anyone to ask when i get to that bolt how to remove it.
Whenever you take the drain screw out, fuel should come out of the bowls. If not, they are either clogged or there is no fuel in them. I don't know of anyway to stick something in the carb without removing it. You're bolt shouldn't be that difficult. Just a swivel socket should do the trick. Probably have to split the side chaps if that is possible. That should get you more room. Is this a carbuerated 4-stroke?
Will this all be the same for a 1987 Johnsonville and evenrude?
Yup, this is basic to all outboards. You are basically going over all the vitals of the engine and making sure you aren't pushing bad fuel into the engine's fuel system. Those old Johnson's though you are going to be draining the carbs and you might have to clean the carbs, depending on the situation.
Born Again Boating Ok thank you
@@roryrichter4723 no worries!
I have a Yamaha 90 that keeps shutting down after running at top in for 40 seconds under load. Does anyone know what it might be. Carburetors have been rebuilt by my mechanic and it’s still doing this.
Still sounds like a fuel issue, the carbs could be worn out or the lift pumps are pumping enough fuel. You could open up the lift pumps and check them out
Born Again Boating thanks for your response. I’ll try
What product do you use to lube the pistons?
Just some engine fogging oil is fine, just to get things lubed before running the engine :) Starbrite Fogging Oil, or CRC Fogging oil, I don't think the brand is as important as just getting some sort of oil in the cylinders
Great!
You guys are awesome
Thank you!
Do you ever acid flush older outboards to clean the water jackets?
Um, I've seen it done, and have done it, but I don't like doing it. It really depends on the situation, I would say that is the last resort.
Besides flushing it with the flush port, what should a person do if they completely cloged a verado 350 with sand, overheated it, immediately shut it down and started it and stoped it a few times until water flowed again? (Asking for a friend) are there any places that need to be cleaned out like the water strainer etc? Thank you.
Hello! It happens, they aren't the first person to do that :) If it's peeing then the water pump impeller is still working fine. It would be good to pull the thermostat and back flush it, clean out the thermostat housing, and then you should be fine. Depending on how mechanical they are, it wouldn't be a bad idea to drop the lower unit and clean off the water pump housing.
Depending on when the last oil change was. You can clean out a 5 gallon bucket and then reuse the oil if it is pretty fresh. Just make sure that the oil drain plug seal gets replaced, don't unscrew it and then put it back in without replacing. It's basically a smash seal, so once it's been smashed, the seal never seals up properly again. It might hold for awhile, but then could leak without you knowing it and possibly run low on oil while out and about!

Thanks very much. From my flow diagram it looks like only smaller components receive strained raw water while the block etc get it all. The thermostat was clean but I should have backfushed from there in hindsight. Seems like everything under the cowling has water running through it...
I will do as told. I already replaced the water pump as I lost a few psi at idle in the weeks that followed. Great channel. GB
So don't let your outboard sit to long
That's it lol :)
Bench cleaning Yamaha fuel injectors is a waste of time and your money.
Ship them to Yamaha and they will clean them professionally otherwise the injectors will gum up soon again.
Yamaha doesn't clean injectors. They sell new ones. But there are companies that will clean them and flow them for you. Flagship is one of the major companies in Florida.

Hello, what's the of?
Ford 19# injectors kid you need to read up!
Do they work in an HPDI?
I could have watched another 20 mins of this job. 😪
She had some serious junk in the fuel
Oh yeah, this thing was pretty nasty. It has been sitting for over 6 years that I know of! I got three of the injectors cleaned yesterday. Now I need to clean out the injectors that wouldn't come out. :( Hopefully it is just the injectors and it's not something wrong with the high pressure pump. This engine isn't worth putting that kind of money into!
I kno
"VST" What a hell is that? If you are doing a tutorial video, do you think you can pronounce full words for general public/ no mechanics ( which I suppose know how ro do that job) understanding?
The VST is the vapor separator tank. It is similar to the FSM or fuel supply module on Mercury outboards. We wrote an article about it, link is here if you are interested www.bornagainboating.com/what-is-an-outboard-fsm-or-vst/
