Thank you for watching! - แนวปฏิบัติและการใช้ชีวิต
not having to fog the old 2 smokes anymore is great!love my new 4 stroke engine!
I just watched this video. Very helpful! I believe I heard a fire alarm system in the background 😄. That’s what I work on for a living
Awesome detailed video. This will be my second yr using ur instructions to make sure I don’t miss any steps. 👍🏻
Glad it was helpful!
Great video gives me more confidence to do my mercury myself...thanks for sharing
Thanks for posting this video! I just bought a used Legend F19 with the 115 Merc.
Great video
AWESOMENESS was a most excellent video THANK YOU SIR
Nicely done, with each step explained.
Great easy to follow video!
If I were buying a new outboard, it would be a Mercury! Long time boater GlennFHoward Florida
Great video! That oil you drained looked new almost like you could have put it back in.
Very good shown and explained
Thank you!!!
Nice video..... good job....
Very informative video, but you skipped the 4th plug removal. This seems impossible to remove. Is there a special socket to reach this one? I can't seem to find purchase on the plug.
Oil drain plug has a place to install a rubber hose, my friends 2001 90hp 4stroke doesn't have one, can they be bought? thanks, great vid.
Great video. Just one question, how many quarts did you put into that motor?
Thanks
Great video! I like my local Lund/Mercury dealer and their mechanic, but I wonder when the guys are going to retire... This looks simple. I think building RC cars was more difficult.
I always bump with plugs out
In this video I didn't see how you did spark plugs, mainly the bottom one which seems impossible to remove
Great Video. Need a starter switch to start the motor from the motor like in the video. What is it called and is their a video on installing one?
Thanks for the feedback. Alex is using a key switch that pugs into the wiring harness
Hello! Really great and instructive video. I have two questions: I have a Mercury EFI 80 2016 which looks very much like the one in the video, I find it very difficult to reach the bottom spark plug, do you have any tips? 2. Do you have a similar video for the 300 hour maintenance? Thanks again for the instructive clip! :D
Same! that 4th spark plug is impossible - the video makes it look easy.
What does it mean to bump the motor??
This motor looks just like my Mercury 75hp. Hopefully the maintenance is roughly the same. I'm worried about the o rings in my lower unit. They may have come out without me noticing. Have a part number for those? Are they all the same size for the lower gear unit?
They can be different. The best way to get the right part is by looking it up with your engine serial number. Mercury has a good electronic parts catalog you can try using on their website
Great video. For those of us that live up north and store our boats in unheated garages or outside, how do i make sure all of the water is drained from the motor so it doesn't freeze?
The outboards self drain so just make sure the engine is in the upright position and all of your water will drain out
@@julianberman8600 Like trim down or on?
@@SethHarvey yes just trim down and the water will drain out the bottom. It wouldn't be a bad idea to check the gear lube for water intrusion but otherwise the engine is self draining (unlike an inboard engine or I/O)
@SethHarvey I trim it all the way up....let it drain....then all the way down...let it drain and that should be all of it. There may be some around the prop so when you take it off to drain the gear lube....it should all be out.
Is it necessary to use a torque wrench when putting prop nut back on?
Typically yes
I have a question: when you say at the beginning at halfway through as well that you’re running the engine after the stabilizer and again on e the oil has been changed, is it safe to do this out of the water? Or do I have to put the boat in the water prior to running it for those few minutes?
hook it up to water so you don't burn the engine up which can happen very quickly.. or put it in the lake.... these motors require water
Great question. @Chuck Bowling is right, you will need water to safely run the engine. We use motor flushers (or "muffs") to connect a regular garden hose to the engine. The flushers are low cost and work very well. Just make sure the water is actually pumping through the engine when you start it to prevent overheating. You'll see a stream of water (tell tale) spraying out of the engine to indicate that the water pump is working.

Probably a Command Thrust lower unit.
Great video, however I've heard that you don't need to spray fogger into this engine anymore. I've read it's bad for some sensors. Your thoughts? Lots of debate online about this.
I am debating on whether I should do this as well. I have the exact same Engine. I have to replace the Plugs this year anyway and wondering if this is absolutely necessary.
Thanks for the feedback! It is true that you don't want to spray the fogging oil into the intake on these fuel injected engines like you would on an older carbureted engine. Because of that, Mercury recommends spraying the fogging oil directly into the cylinders like Alex did it in this video. If you spray the fogging oil directly into the cylinder, it will not damage any sensors or injectors.
It may seem redundant but just keep in mind that you only need a quick mist of the fogging oil. Just enough to coat the cylinder walls. If you're ever in a situation where you think there may be too much fogging oil in the cylinder, just make sure the spark plugs are removed before turning the engine over to prevent any damage
@@kckrol85 I'm sure there are plenty of folks that do not use fogging oil and don't run into issues. That said, the purpose of the fogging oil is to prevent any corrosion from developing on the inside of the cylinders while the engine isn't being used. Fogging serves as relatively cheap insurance against the internal corrosion. Mercury recommends it so we include it in the service
I recently purchased a 90 hp Mercury. Changing oil and filter, fuel filter and lower gear oil tomorrow.
Should I also change out the impeller?
I also have a question about a Water Separator? Should I install one as well? If so, can you do a video on that as well?
Mercury recommends replacing the water pump impeller every 3-5 years or 300-500 hours, whichever comes first. Some boats have water separators installed, some don't. It's up to you. We don't have a video on installing a fuel water separator but maybe we can in the future. Thank you
@@julianberman8600 I most definitely want to install a water separator. I’m not sure which fuel line to use. There are three fuel lines coming from the tank.
I stalked to a Mercury Technician, absolutely no help.
@@rodneykaneaster3292 Yeah each boat is a little different. I'd recommend bringing the boat to your local dealer
How do you take off the cover?
You can read the owners manual :-)
55 lbs of torque. You need to use a torque wrench when reinstalling prop.
So you dont have to run antifreeze through the water intake?
The Mercury outboard is self draining so you don't need to run anti-freeze thru it. It's a good practice to tilt the outboard all the way down so it drains any water in the gearcase and if its outside and tilted up we cover the prop so snow/ice/rain don't get into the exhaust area.
Informative video, Do you recommend running antifreeze thru the motor in cold climates ?
Some people do but it's not necessary
My 115 is on a fishing boat and I fish all year do I need the fogger?
Mercury recommends fogging for storage so if you're using it all year, I'd say you don't need to fog it.
Nobody's gonna mention the fire alarms and fire department in the background? LOL
LOL. We are located next to college dorms and the fire alarms are going off constantly!
What about the water in the engine? Do you have to run antifreeze through the engine?
When the motor is upright, the water will drain out so running antifreeze is not necessary.
@@julianberman8600 I really appreciate you responding to my question on a 3 yesr old video. Thank you.
Will Marinas let you do your own maintenance?
Yes
like
No need to run antifreeze? I like this method better lol
You don't need to run antifreeze in an outboard motor but it won't hurt. Some people run antifreeze for peace of mind
This video would have been an absolute ten if you had a better cameraman. The cameraman didn't zoom in during any of the key moments.
Exactly why I would never let a marina/boat shop service my motor!
Winterizing is for Yankees!
Don’t buy mercury motor they suck..👎👎..
Actually they are the very best.
@@mcplutt how so? If they are the best why do most people complain about it?
@@hgherb I haven't heard much complaints.
@@mcplutt well now you know. 😆
@@hgherb I just know what you say :-)
