That's a great engine. I purchased mine in 2018 for my 11 ft Whaler short shaft with electric start and steering wheel. I get 30 mph top speed with me (205 lbs) and gear in the boat.
I have the same motor (20” shaft with electric start). Replaced an old 2 stroke Merc on a 15 ft Mirrocraft Stryker. After two seasons here in Wisconsin, I have no regrets. Starts in any weather, quiet, and sips gas. The vibration at idle does shake everything in the boat but it’s a small price to pay for the bullet proof reliability. My boat is heavy but it will still push 22mph with 2 people and gear. I paid $3,800 in 2019.
The reason it vibrates is because it doesn’t have a counter weight to balance the pistons. Other small 2 cylinder motors have them to balance them. This is how Yamaha lowered the weight on the new lightweight 25 hp. I got that straight form Yamaha when I bought mine.
They're excellent engines. I have a 2 stroke 25 on one boat and a f25 on my other boat, both excellent, absolutely zero complaints out of either one...it's kinda cool having two of the same horse power engines, one being a 2 stroke and other being a 4 stroke ...I can do direct A to B comparisons in the differences.
@@6___________99_____________64 I like the 4 stroke due to its efficiency, ability to idle, super reliable, and its quiet...I like the 2 stroke, because it is a bit quicker, it's simple, lower maintenance costs and runs like a raped ape...
@@c.shoefish 2 stroke FTW !!! Just bought my 1st 4 stroke motor (Suzuki 6hp) taking it to the dam tomorrow to break in and see how it runs . I also like 2 strokes myself. Simplicity is key
What makes a 2 stroke more simple in your opinion? IMO a 2 stroke is more complicated than the F25 because it’s carbureted, and you have to mix your fuel and/or fill up your oil injection. F25 is gas and go. As far as maintenance, you still gotta change the oil, plugs, wires, impeller, fuel filter, just like any other outboard. Just wanting to understand your side.
@@FloBass Ive been running 2 stroke carbureted engines for decades, they just speak to me I guess🤣 no EFI, less wiring, no valves to adjust, mine is pull start so no charging or starting system to worry about...in the end maintenance costs are probably about the same...I love both, they each have their purposes...both run excellent, but I enjoy the 2 stroke more in certain situations, and the 4 stroke in others...
I paid $383X out the door for a 2020 model in July of 2020. I got the same model as you but with electric start. It included a 3 gallon tank and fuel line plus dealer “setup” which was simply fill with oil and run it to make sure it was pumping water and then oil level recheck.
This is a good motor, i have the 9,8 Tohatsu 2 cylinder 209 ccm no and 150 hours, start in a lake, out in salt and back a channel in shallow tilting. Before i have this 71 kg Tohatsu 3 sylindered 25 and that was a good one, didnt change impeller until it started go bad and it lasted 12 years 1100 hours before boat stolen and crashed.Impeller change after 8 years..Ihave one yamaha 8 one year and also a ok engine. But no recently Tohatsu came out with a 500 ccm 3 sylyndred 25 the same weight as this yamha 25,. Next time if in the new engine purchase, i definately go for the 3 sylindered.But all are exellent engines. Al the best from Norway and have good boating trips=)
Excellent! I just had mine out for the first time, I wasn’t concerned with the weep hole strength but I also noticed she shook a lot and the handle vibrates at idol but like you say any throttle at all and it’s gone, nice and smooth. Glad it’s normal. It ran flawlessly and it’s got some torque, the swivel tension feature came in handy. I’m happy.
I replaced. 20 Tohatsu with this Yamaha ( with some extra features). Straightaway I was thinking the cooling water was way weaker than the old motor. Great motor though 👍
Good video I have an f25 on a Lowe roughneck 1860 runs 23 mph loaded Idid install the electric start ,it was an easy install , and it sure makes it alot nicer but the electric star kits have really increased I only paid 330.00 dollars for mine last year. I really think these motors should last a along time .Congrats on Captain s license hope to get mine soon. I am going to get one of those cmc trim plates when I find a used one because they have really increased in price also.
Great videos Eric! Very informative. I notice that you have a Runleader tach on your F25. Can you tell me what firing pattern you have it set to? I'm trying to set up my tach as well. Thanks.
I bought mine 4 months ago...from start it have some aditional noise from engine,and vibrate like hell...off course strougle and fight with official service for a while.But at the end of the season a will return them to check every single thing.
DUDE AWESOME VIDEO 🤙🤙🤙IM LOOKING AT A 40HP 4 STROKE FOR MY 14' BAYLINET... JUST THE REVIEW you gave of your motor REALLY HELPED ME OUT ALOT 👍👍👍WHATS THE NAME OF THAT LAUNCH RAMP? THATS A NICE 1 LANE RAMP... ✌✌✌
Is that a 1448 you got because I got a 1448 with a 20 horse Suzuki and I wanted to upgrade to the 25 I don't know if it's a too much heavier or if it's a good fit or not.. I mean do you think you would be a good match for a 1448??? We have the opposite I have the electric start but not the power trim and if you practice chewed up that will cause vibration as well
I bought a portable home generator years ago and I wish now that I would have paid extra for electric start. At the time the savings seemed important. It's gone the other way as well, where I bought extras on things that I learned later were not necessary. Great video.
Thanks for your honest review and the sights of the superb waterway on the front of your property! What happens when the river swells? What a smooth motor! I would love to have it in my Boston Whaler Sport 11!
You mention you would go to a stainless prop, what one are you thinking about getting and what pitch? Would you do a review on it if you get one? I got the same motor and contemplating going to a ss prop too.
Does not having power trim help reduce damage to motor if you do hit a log? I would think power trim would lock the motor down while in forward? I am asking because I am getting ready to purchase this motor in the next day or two. I can choose between the bare bones or the one with electric start and tilt assist. I will be using the boat in really sketchy water with lots of logs (and gators). Price is not a concern. Damage to the prop and shaft certainly are.
I’ve watched every video you’ve done on your F25. Great work. Suggestion for another video: how did you determine the trim pin position for your boat considering sometimes you’re alone and sometimes you guide?
Thanks for the support, Tony. A good video idea for sure. You actually gave me a good idea to put a slight twist on your suggestion. I'll see if I can get it done next time I take the boat out.
@@FloBass thanks! I know you have the power tilt now but for those that don’t, and/or don’t understand how important the trim is, it would be good. Even me, I realized end of last year I was probably too low on my old 15hp. I want to get it right on my new F25.
thanks for posting this have been looking at this engine for my boat was wondering if i really needed the electric start power tilt trim i had the features on bigger boat use to own that had forward controls i have a 25 hp tohatsu 2 stroke atm manual start and manual tilt tiller steer looking at upgrading to a four stroke efi model way go also
EFI is the way to go. I haven't touched my boat since the end of July because I was up north on a fishing trip, then when I came back other people hosted me on their boats, then I fished a month long kayak tournament on the weekends, and I finally started her back up for the first time and she started on the second pull like nothing.
Great video and great engine! Just a few questions, do you what's the top speed with your configuration? And also, would you recommend it over a two-stroke engine, and why? By the way, you said that the power stroke happens every two strokes (180° phase between the two cilinders): that's usually what happens in 2-cylinder engines, but in the F25 case I read on the Yamaha website that the two cylinders fire simultaneously so the engine actually acts like a 1-cylinder one! (This might also be why it vibrates consistently when idling, obviously they chose to let it smoother when cruising)
Many reasons why I would go with a 4 stroke over a 2 stroke. Easier to maintain, no mixing oil with fuel, cleaner running, more fuel efficient, quiet. The boat runs about 30mph when its just me in it with perfect conditions. When I have another person it averages 26-28mph depending on where they sit, and the wind.
Your choice on cmc tilt is better than OEM, it is serviceable and cheaper. Prop, the stainless won't flex on 25hp motors, and are heavier to spin but for the same pitch they are thinner more durable, so it's a wash. Yammie props are best, don't waste $ on aftermarket, I tried them. The tiller handle vibration can be fixed, tighten the gland but behind the sleeve one turn to tighten handle then remove tiller handle add a washer inside on the spring when you remove the handle.
I have an idea about the "weak stream" from the telltale i have and older '71 merc 110 9.8 hp it doesn't have a thermostat and even at idle the stream is very forceful because there is no thermostat to slow down the flow of water. In my new 2020 Merc there is a thermostat and at idle the stream is much weaker untill the engine gets nice and hot then theres a lot more water shooting out the telltale and the water is warm instead of cold. Im no mechanic but i belive the thermostat opens at a specific temp allowing more water to flow into the engine to cool it down. Whereas older engines without T-stat has full water flow all the time
I have this motor with factory electric trim and start. Wondering if anyone else has my problem the power trim won’t work above 3/4 throttle, hydraulic noise like it’s under too much load like when putting motor on motor support for transport. My cavitation plate is 25mm below hull plane so don’t think I am too far off height. Motor is on a f14 Frewza (4.4 meter alloy pontoon boat)
What model was the 14’ Jon boat you first put it on? Also, would you consider going down in hp to 20 or 15 to get more features like power tilt and electric start? Thanks
It was a tracker 1436. I wouldn’t drop down in horsepower. The loss in power to push the boat with 3 people in it is not worth it. A boat with a smaller engine struggling to get on plane uses more fuel than a boat with a bigger motor operating on plane.
Hello, when you do you static flush are you getting water coming out of the lower unit bolts? I can see a small hole next to the bolt but not sure if that’s normal?
No can do. Upgraded to a flats boat. There's nothing else to say about the F25. It's rock solid. I beat the crap out of it and it ran like new the day I sold it.
I have that same setup im installing a cmc pt 35 soon i was curious to were your cavitation plate on your motor is to the bottom of the boat it says 1”-3” high do you think yours is at a good height thanks
I mounted mine on the high side. I'm right at 3" and would go lower next time. Cavitation plate should be level with the bottom of the hull. If I went with a prop that had more cup to it, I would have gained more performance keeping the motor up so high. Stock prop needs more water to work properly.
yamaha are durable engines but unfortunately on the smaller ones like 20 hp and 25 hp they only have two cylinders and vibrate quite a lot. Since you don't have power trim, it also becomes very heavily steered when you pull as you can't adjust the engine up and you have to struggle to keep the tilt all the time as it pulls on the engine. Replaced my yamaha with a new Mercury 30 hp and what a difference in engine. It runs so incredibly smoothly as it has three cylinders and the tiller has so many adjustments and you have the power trim original and what a low draft in that engine and very easy to control at all revs and you don't have to wrestle with the tiller at higher speeds. But above all no vibrations, it is very irritating as it vibrates constantly in the Yamaha.
I've got almost the same setup with a yamaha 25hp and the CMC 30 and the 25 mounting bracket is actually the same size as the CMC mounting plate, leaving no good spot to bolt them together. Did you figure out a way to bolt the motor to the CMC?
No, I haven't bolted the motor to the CMC. I just clamp it. I haven't had any issues so far. I put some skateboard grip tape on the clamp side of the CMC to give the motor some traction so it doesn't slide around. The only way I can see getting bolts to work is to drill and tap the CMC.
@@FloBass no. I had a top speed of 28 mph and then it started hesitating getting to plain. It would feel better one run then I’d barely get on plain on the next run. Very inconsistent. I bought new gas line, cleaned the fuel tank out and got new fuel, cleaned the gas tank intake. Replaced fuel filter, water pump impeller, spark plugs, deep clean on carburetor, new fuel/water separator, and had compression checked (180 psi on each cylinder) I’m really at a loss for what it might be. Engine turns right on and idle nicely. It’s when I give it gas is when it SOMETIMES hesitates. My top speed as of yesterday was 24 mph. Acceptable - but not what it was. My motor is a 2018 and I’ve got 150 ish hours.
Tough one to diagnose when its intermittent. Could be fuel, or maybe heat related. Float could be getting stuck and not filling the bowl, could be a vacuum leak somewhere, maybe the ignition coil is going bad.
Hi, this is perhaps a silly question but where on the motor do you connect your battery charging cables to? I have the same model and just can't find the 12V power supply connector. Many thanks, G.S.
Not sure if you answered this question already.... here goes: does adding electric start to this model give you the ability to charge the start battery?
my 2005 Tohatsu 9.8 vibrates less with slight throttle as well. It has electric start but i prefer to use the pull string. id imagine your motor is probably harder to pull start though. What power tilt in that? does it also work like a jackplate?
Does anyone know why this OB leaks a bit of gas after use when its stored on its back? Its a Yamaha approved position, resting on the two "feet", tiller up. Assuming theres some sort of fuel collector on the return that leaks out a vent line?
@@FloBass Thanks for the response. Its weird. Take it off the boat and store it tiller up, and I get maybe a tablespoon of fuel out from....somewhere...... Works fantastic otherwise. Running a 10" pitch prop on a 15 1/2' Mercury inflatable. Great motor. Cheers.
You and your yamaha got a weak stream, HA! Mercury! mercury! mercury! Just bustin balls lol. Congratulations on the captains license by the way. Pretty cool.
@@FloBass Im seriously debating picking up one of these motors. Im afraid it wont hold a candle to the performance of my old 2000 25hp Johnson. I was seeing 32mph with that motor
Depends on the boat, load, prop, motor height, and trim. I was able to do 33mph banging the rev limiter when this was on my tracker 1436 with just me in it and a couple rods and the lures I was fishing for the day. No jack plate, no power trim. So even with bad motor position, just changing a prop to one with more pitch would have netted more top speed. A buddy of mine has a 2001 two stroke 25hp merc on his gheenoe and we go the same speed. He doesn't have a jack plate though and the motor sits pretty low, so he could go faster if he jacked it up higher.
Correct my friend. There’s a lot of reasons I’m not interested in guiding Ida right now. Only fun fishing for clowns on artificial is all I’ve been doing there lately.
Haha well its actually a serious thing to watch out for here in South Florida. Especially when the water is low and funnels all the fish and gators into the canals. You nail a big one and its literally like hitting a brick wall.
I'm going to have to call you out on that one. Sure, I'll eat my words if you can produce a receipt and shipping label, but you are spewing a bunch of bull. Overtons doesn't even sell Yamaha outboards. They never have. They only sell Zukes and Hondas which with their portable outboards, don't require you to go through an authorized dealer. Some places do sell Yamahas online, but only ship to Yama dealers.
No compression release for starting? Not buying trim and tilt was a major screw up. Now u spent more having to buy after market plus resale is not as good. People prefer oem features not bolt on. Maybe u put your water pump impeller on backwards. Rookie.
Keep the aluminum prop dude..it's a cheap insurance policy stainless if you hit something big you can fuk it up bad!!! I seen it I happen more then once I got the suzuki 25 2021 just as good...
That's a great engine. I purchased mine in 2018 for my 11 ft Whaler short shaft with electric start and steering wheel. I get 30 mph top speed with me (205 lbs) and gear in the boat.
I have the last of the 2 stroke Yamaha 25s bought new in 2006, still have it, had zero issues! I run it on my honwave 3.8m inflatable.
What’s you’re cruising and top speed with the 2 stroke Yamaha on your 3.8?
I have the same motor (20” shaft with electric start). Replaced an old 2 stroke Merc on a 15 ft Mirrocraft Stryker. After two seasons here in Wisconsin, I have no regrets. Starts in any weather, quiet, and sips gas. The vibration at idle does shake everything in the boat but it’s a small price to pay for the bullet proof reliability. My boat is heavy but it will still push 22mph with 2 people and gear. I paid $3,800 in 2019.
Sounds about right. I'm glad to hear its been good to you as well.
The reason it vibrates is because it doesn’t have a counter weight to balance the pistons. Other small 2 cylinder motors have them to balance them. This is how Yamaha lowered the weight on the new lightweight 25 hp. I got that straight form Yamaha when I bought mine.
You sir are a Super Hero for this video. Much Blessing to you.

I believe water got into gas tank. Bogged down shut off a mile from ramp. Would love a tip. Same motor. The carb looks different and that scares me.
Definitely not the same motor if it has a carb. The F25 is fuel injected.

Is it easy to chage the fuel filter? you just screw it out and put in new filter?
What model was the 14’ Jon boat you first put it on? Also, would you consider going down in hp to 20 or 15 to get more features like power tilt and electric start? Thanks
It was a tracker 1436. I wouldn’t drop down in horsepower. The loss in power to push the boat with 3 people in it is not worth it. A boat with a smaller engine struggling to get on plane uses more fuel than a boat with a bigger motor operating on plane.
Also, my motor is offered with electric start and power trim. In hindsight I would have waited and went that route.
Thank you!

yamaha are durable engines but unfortunately on the smaller ones like 20 hp and 25 hp they only have two cylinders and vibrate quite a lot. Since you don't have power trim, it also becomes very heavily steered when you pull as you can't adjust the engine up and you have to struggle to keep the tilt all the time as it pulls on the engine. Replaced my yamaha with a new Mercury 30 hp and what a difference in engine. It runs so incredibly smoothly as it has three cylinders and the tiller has so many adjustments and you have the power trim original and what a low draft in that engine and very easy to control at all revs and you don't have to wrestle with the tiller at higher speeds. But above all no vibrations, it is very irritating as it vibrates constantly in the Yamaha.
Good video!👍
How slow ( MPH) can you idle it down to?
Thanks
I've got almost the same setup with a yamaha 25hp and the CMC 30 and the 25 mounting bracket is actually the same size as the CMC mounting plate, leaving no good spot to bolt them together. Did you figure out a way to bolt the motor to the CMC?
No, I haven't bolted the motor to the CMC. I just clamp it. I haven't had any issues so far. I put some skateboard grip tape on the clamp side of the CMC to give the motor some traction so it doesn't slide around. The only way I can see getting bolts to work is to drill and tap the CMC.
Where can I find the power tilt kit? I have a 2023 25hp.
TH marine. Bass pro also sells them.
Have you ever had HP issues with yours? I’ve been trouble shooting some fuel starvation (at least I think) with mine. It’s been super frustrating
Never had an issue. Is your feed line from the tank to the motor kinked or pinched anywhere?
@@FloBass no. I had a top speed of 28 mph and then it started hesitating getting to plain. It would feel better one run then I’d barely get on plain on the next run. Very inconsistent. I bought new gas line, cleaned the fuel tank out and got new fuel, cleaned the gas tank intake. Replaced fuel filter, water pump impeller, spark plugs, deep clean on carburetor, new fuel/water separator, and had compression checked (180 psi on each cylinder) I’m really at a loss for what it might be. Engine turns right on and idle nicely. It’s when I give it gas is when it SOMETIMES hesitates. My top speed as of yesterday was 24 mph. Acceptable - but not what it was.
My motor is a 2018 and I’ve got 150 ish hours.
Tough one to diagnose when its intermittent. Could be fuel, or maybe heat related. Float could be getting stuck and not filling the bowl, could be a vacuum leak somewhere, maybe the ignition coil is going bad.
I'm GUESSING the fuel economy Must be pretty good on it If your boat is fairly Light ???
Its awesome. I can get about 80 miles out of a 6 gallon tank if there's no wind or strong currents.
@@FloBass 13 m p g cool some big gass guzzler autos don't do this good---lol
Hi, this is perhaps a silly question but where on the motor do you connect your battery charging cables to?
I have the same model and just can't find the 12V power supply connector.
Many thanks,
G.S.
This motor doesn't come with the ability to charge a battery.
@@FloBass
Thank you :)
Did you ever add the electric start?
Negative. Sold the boat before I decided to.
Most of the cooling water comes out of the exhaust. The weep hole is just to confirm that the pump is at least operational.
Thank you good stuff
Not sure if you answered this question already.... here goes: does adding electric start to this model give you the ability to charge the start battery?
No, adding it will not allow you to charge a battery. Most outboard manufacturers make a rectifier kit that will do this.
my 2005 Tohatsu 9.8 vibrates less with slight throttle as well. It has electric start but i prefer to use the pull string. id imagine your motor is probably harder to pull start though. What power tilt in that? does it also work like a jackplate?
Its a CMC-PT35 power trim. Unfortunately no one makes a power trim and jack plate combined.
70 miles on a tank. Is that nautical miles or land miles? I just bought the F20 with electric start and I'm just exploring the range potential.
Land miles.
IS THERE ANY PLACE YOU CAN ORDER ONE ? THER IS NOT A SINGLE BOAT SHOP IN COLORADO THAT HANDLES YAMAHA !
Can this motor help bring back home a 30 ton 70ft cruiser?
Is this a serious question?
Hello. It is correct for water to come out of the idle hole?
Yes that is normal
How do u fix over flow of gas?? Like what's broken ?
I didn't say anything about that in this video, so I have no idea what you're referring to.
Nice engine buddy 👍👍👍...
Hello, what about high vibration on trolling mode? After F15 the vibration on hadle is to high!!!
I think people make too big of a deal about the vibration.
When you had this motor, did it have a small squeal? At idle or slightly in gear. Goes away at higher RPM
Where did you order the power tilt from , I want ed on my new motor 25 short shaft 4 stroke , they do come with it ?
Does anyone know why this OB leaks a bit of gas after use when its stored on its back? Its a Yamaha approved position, resting on the two "feet", tiller up. Assuming theres some sort of fuel collector on the return that leaks out a vent line?
No clue. This doesn’t happen with mine.
@@FloBass Thanks for the response. Its weird. Take it off the boat and store it tiller up, and I get maybe a tablespoon of fuel out from....somewhere...... Works fantastic otherwise. Running a 10" pitch prop on a 15 1/2' Mercury inflatable. Great motor. Cheers.
nice video man when I get my 50 I'll sell you my mercury 30
A Merc? I enjoy reliability, sir...
@@FloBass 🤣 mercury the best on the planet
Please tel me whot and whare you got the motor tilt
Amazon! amzn.to/3PZEISf
Thanks for your help
but heavy engine 60kg or more ?
You and your yamaha got a weak stream, HA! Mercury! mercury! mercury!
Just bustin balls lol. Congratulations on the captains license by the way. Pretty cool.
Yamaha 💪🏻 > Merc
LOL thanks, Anthony!
4200 out the door here in Washington state
Crazy out much inflation has affected the price on these.
What’s your top speed
28-30mph depending on wind.
How much would you sell the 9.9 yamaha?
Sold that motor about 3 years ago.
E um elelente motor como faz pra ver presso
How fast does it push your boat?
By myself I can go about 30mph if I put the weight up front. With another person about 28.
@@FloBass Im seriously debating picking up one of these motors. Im afraid it wont hold a candle to the performance of my old 2000 25hp Johnson. I was seeing 32mph with that motor
Depends on the boat, load, prop, motor height, and trim. I was able to do 33mph banging the rev limiter when this was on my tracker 1436 with just me in it and a couple rods and the lures I was fishing for the day. No jack plate, no power trim. So even with bad motor position, just changing a prop to one with more pitch would have netted more top speed. A buddy of mine has a 2001 two stroke 25hp merc on his gheenoe and we go the same speed. He doesn't have a jack plate though and the motor sits pretty low, so he could go faster if he jacked it up higher.
What is the wot rpm.
Prop size and pitch .
Boat weight.
4 stroke engines wot should be at or very near
the top of the rpm range of the motor.
Thanks
No Ida then eh?
Correct my friend. There’s a lot of reasons I’m not interested in guiding Ida right now. Only fun fishing for clowns on artificial is all I’ve been doing there lately.
Lol “I’ve hit an alligator or two”. You don’t hear that every day.
Haha well its actually a serious thing to watch out for here in South Florida. Especially when the water is low and funnels all the fish and gators into the canals. You nail a big one and its literally like hitting a brick wall.
Woohoo! I'm "like" #200!
Sorry, but I actually DID just order this online. Straight from Overtons. Came right to my door like any other item you’d order online.
I'm going to have to call you out on that one. Sure, I'll eat my words if you can produce a receipt and shipping label, but you are spewing a bunch of bull. Overtons doesn't even sell Yamaha outboards. They never have. They only sell Zukes and Hondas which with their portable outboards, don't require you to go through an authorized dealer. Some places do sell Yamahas online, but only ship to Yama dealers.
@@FloBass I’m dead serious! Go look, there are brand new Suzuki outboards there to purchase. I got a white 25HP shipped to my foot via freight.
@@FloBass Nevermind. I’ll eat my words haha. I read your comment wrong and in my head was thinking Suzuki. You’re right. No Yamaha.
I use a 12 volt motorcycle battery to start Yamaha 25f. It cut down on the weight in my boat.

Capitan license what ta hell what you have go to school to get a capital license. I think that's stupit
It's called a captain's license and is required to operate certain vessels, who wants an incompetent operating a vessel?
No compression release for starting? Not buying trim and tilt was a major screw up. Now u spent more having to buy after market plus resale is not as good. People prefer oem features not bolt on. Maybe u put your water pump impeller on backwards. Rookie.
Keep the aluminum prop dude..it's a cheap insurance policy stainless if you hit something big you can fuk it up bad!!! I seen it I happen more then once I got the suzuki 25 2021 just as good...
