25 Horsepower 4 Stroke Yamaha Jon Boat Max Speed Test

[@kgilliagorilla2761]

I have a 03’ Yamaha 25 four stroke on a Lund 14 SSV tiller.It’s a deep V, very light boat. Just me and gear about 28 mph. I don’t have electric tilt & trim. I had to install a fin on the cavitation plate to get up on plane easily. It also made it ride much “flatter”. No dolphining. On a flat bottom boat I don’t know if it’s necessary. Nice boat you got there. Congratulations on captains license. Cheers from Chicago

[@stephenpersic9474]

I think that your boat doing 30 mph is really great , that's very fast on water and having the well full didn't affect your speed at all , still 30 mph which is awesome I'm sure even with another person you can still get 30mph

[@AlexGarcia-ew2fv]

I have a 14ft jonboat with a 25hp yamaha 2 stroke motor...with 2 people I'm consistently doing 32mph wide open in the Everglades in Miami fla

[@locker1325]

Great video. All the information I wanted without endless commentary. I think 25 hp is a perfect size for this boat. The well was a Great idea for simulating weight.

[@dougweaver8317]

I have a 1542 with a 25HP 4 stroke, added floatation pods to the transom, made a huge difference in performance and no water coming over the top of the transom. Well worth the money.

[@caryralls7488]

Thanks for posting. Been looking at this exact same motor. I've got a 15hp 4S on my 16' Lund and it suuuuuuucks! 22mph top speed just me. Two more guys and drops to 15mph tops.

[@FloBass]

Thats not bad! I was only doing 9-10mph with basically the weight of me and two other people with my 9.9. If the boat gets on plane, you're in good shape. I haven't had the same payload with the 25 yet, but I'm guessing it will do around 28.

[@Treestandtroubadour]

Sounds bout right honestly man

[@rhonytrujillo9700]

I was doing 37 mph with an f15 in a 12w and a 12 pitch prop. The trick is engine height and trim. I made a jack plate for mine and ran my cavitation plate 1.5 inches above the bottom of the boat.

[@zsozsousa1]

did you do the test run? it is better?

[@1minibean]

@@zsozsousa1 yes sir I did. My engine pushed he 12 pitch with ease.....the problem is the Solas prop is heavier than stock, and didn't agree with my engine as it made a terrible noise (videos are up now ). GPS runs complete.

[@zsozsousa1]

1minibean thanks. I just tested a newly bought 1440 jon boat. Top speed was under 10 mph with mercury 2005 15 hp engine. Trying to find the issue that cause the slow speed. I boat has some extra weight due to mods and it was with two people bit it’s still below normal speed, I would say... The prop I have is a polastorm 9 pitch, I thought maybe thats the issue, but I am not sure. Any idea or tip?

[@1minibean]

@@zsozsousa1 sounds low, with the weight you described and the 15 hp, 2 stroke ? Are you planning? Should be around 15 or 18 mph maybe....

[@ve3xtr]

So excited. Just got a Yamaha 25 but haven't used it yet because the boating season is over up here (toronto). Have to wait until April, if I'm lucky. The speed is comparable to my crap Tohatsu 30 EFI with the broken ECU. And its only 7 years old.

[@FloBass]

It's been a great outboard for me. You'll enjoy it when you can get back out onto the water.

[@jimmylanders2693]

i am going to start off with saying good luck with your captain license. i am a 100 ton QMED. generally speaking, you should hit rev limiter unloaded, but never loaded. adjust prop pitch accordingly (+/- 1 pitch) in your case. it seems like your boat could only accommodate 2 or 3 persons max. factor in the weight of the people and gear +(cooler of beer). all of the weight will mostly make its way toward the front which will make planing more difficult. if you did your speed test in fresh water you may want to go to salt on a calm day. you will gain some speed for bragging rights. saltwater is more dense and the boat floats higher. same way when we swim in it (easy to tread water). pitch the prop for how you will use it commercially and keep the prop now for recreational use. stainless props are nearly indestructible and have incredible wear resistance to bumping in to sand bars and such. however, they are heavy and send a shock wave to the gears in the lower unit when shifting gears.

[@FloBass]

Thanks for the info!

[@SoUThCReATiOn]

Flo Excellent video!!!! I have a 10ft Tracker with a 3.5hp 4 stroke Mercury and I run the Mississippi River in mines its just rite for my one man weight limit I might upgrade to a 6hp

[@FloBass]

I watched a couple of your vids. That boat moves pretty well with that motor. Some rough water. I don't think you'd want much more than a 9.9 hp because you wouldn't get to use it unless it was calm. For the distances I need to travel to put clients on fish I gotta travel at least 20 mph. No more than 25.

[@pain_weaver]

You should get twin 50s. 😂😂

[@patriot6426]

My 14x48 aluminium John boat with a 2006 25 Yamaha two stroke runs around 30 or so with me my son and light gear! Love the rig , I can get in super shallow water, we do alot of pan fishing and catfishing! I can't say enough good things about my Yamaha! Good video man!

[@gvyberv]

To solve your water over the transom issue pull the pin and adjust your trim down one level. I had the same issue until i adjusted the trim and problem solved. You may get better perfomance as well. At least I did.

[@FloBass]

I’ve messed with it in each setting. I see no difference. It sits so low in the rear there’s not much that can be done.

[@gvyberv]

@@FloBass that is true i forgot about that. My transom is a few inches longer in height. Look into getting a jack plate which I Highly would recommend. I really want to make sure you get the best out of your boat and outboard flawlessly.

[@1minibean]

I just ran the testing with the 12 pitch prop vs. the stock 11 pitch on the DF25A. 3 mph faster top speed, the engine loves the prop. BUT - I noticed it takes more to get up on plane. The truth is I put the 11 back on because I prefer to have that perfect blend of hole shot and mid range beastly power and ease of on plane times and be satisfied with 27 mph top speed. I used a solas amita prop and I have a chirping or kind of squealing going on which drove me nuts, not sure why. I never had that happen with stock prop. I also noticed my motor mount bolts were loose, this may have been the cause of the noise. (22 hrs. total time on the boat and Motor). I will retest on the next nice day. I posted a video last night of the chirping noise. - Thanks, Jeff

[@FloBass]

Awesome info! I hit a gator yesterday morning and put a dent in my stock aluminum prop. I lost 1mph. I’m going to have to replace it. The thing surfaced 20 feet in front of the boat when I was cruising at half throttle which is 22mph. Nothing I could do. How heavy is your boat?

[@gilgonzalez1507]

Bro just got me a jon boat. I cant wait to get it ready for the water. Thanks for the videos.

[@FloBass]

I appreciate you!

[@1minibean]

I love it.... I have a new 2019 Suzuki DF25A on my new 2019 smokercraft V14 and I am getting the same numbers. With my wife and 75 lbs.daughter and a full cooler for the day I am getting 27-28 every time. I have a stock 10 1/4 - 11 pitch prop. The thing is, I have the same speeds at 3/4 throttle as I do wide open, but there is always a big hit of thrust that snaps my head backwards when I hit the throttle no matter where it's at, but no more speed. I can't seem to figure it out....makes me think it can handle a 12 pitch. There is no limiter hitting, but I have that extra thrust all the way through the range even when the numbers stop. That 3rd cylinder really helps with torque, but our numbers seem to match with your Yamaha. My boat is a bit heavier, I believe it's at 185 lbs dry. I'm afraid to run stainless because there is no give when hitting shit in the water. I live in upstate NY Saratoga Springs and we only have the fresh water up here and it's got lots of tree and rock to look out for. Let me know if you think of it when you get a different prop, I'd love to know what you discover with it. Love the Yamaha, its sweet. I'm at 147 lbs dry with my electric start engine, and manual tilt doesn't bother me either, I just find the sweet spot and leave it there all day. I also have a 15 inch shaft motor and boat transom, it's a menace for many reasons.... Thanks man - Jeff

[@FloBass]

That smokecraft is a nice boat! The 3 cylinders will give you a great holeshot. Always was curious about those Suzuki's. The best thing to do is get a tachometer and note your rpm at full throttle and top speed and talk with a prop shop. You'll also need to know the weight of your boat as well. They'll be able to tell you if a prop with a different pitch will help or not.

[@shawnhagen6871]

Trim that motor up, when you gave the drone footage you could see the front of the boat had layed down on plane. Keep the bow up and you’ll add 3-5 mph. Not to mention it won’t prop wash as bad in reverse. I’m running 20 mph, 2 people, gear, 14-36 war eagle with a 9.9 Yamaha 4stroke. Running a 15hp carb & stainless prop

[@FloBass]

Yeah I wanted to put a 15hp carb on my 9.9, but I knew it wouldn't be enough especially with my baitwell. It already bangs the rev limiter even with another person in the boat along with a full well so I'm not sure if I'll get any more speed out of it, but I'll give it a shot.

[@victorpeirce4753]

*Trim it out as far as possible. All these imbeciles saying put weight up front have zero idea. You want just the prop in the water and the nose slightly raised,not ploughing through the water like it is. You will pick up 10 kmh in top end speed. You lot are clueless about getting the best performance out of a boat.💯%*

[@brrepublic8174]

This is impressive results. And the F25 is a compelling option if you're stuck deciding between a 20 and a 25 tiller, the Yamaha F25 is basically a strong 20 as it is a 2 cylinder design, it has less displacement (432cc) as the 3 cylinder brands (500cc) but more than the 20hp 2 cylinder options (>350cc). It is a true in between and offers the best combo of power and weight savings. I'd like to know what the fuel burn difference is compared to a Tohatsu 25 and see if having less displacement makes a difference (even though the Tohatsu is working less hard).

[@SkypowerwithKarl]

I’d go with the same pitch but a quality stainless one, this will load it just a tad so you don’t tag the limiter when it’s just you and still have enough holes shot when you have two bodies and gear. Keep the old prop and tools onboard, if you’re prepared you’ll never need it luck.

[@michaelhamilton3778]

[@takinitoutdoors450]

Nice video, just to offer some experience, I have the same motor electric start. I run it on a 1548 semi v. Stock Yamaha prop is 9-7/8 dia by 11.25 pitch and would push me and my buddy total weight 525lbs and fishing gear 27-28 I now run a solas stainless 10pitch for pushing heavy loads it’s a slightly larger dia so it pulls harder down low and maneuvers the boat better at low speeds it will push 4 people and fishing gear 24-25 mph. My back up/ go fast prop is a turning point aluminum 9-3/8 by 11 pitch very close to the Yamaha prop at a 1/4 of the cost. If you want to chat sometime drop me a message good luck.

I had a $3,800 lb Sea Ray and the motor would push that boat at 36 same motor on an 1800 lb boat top speed the same 36 it depends on how the gearing is and the prop that you're using. If it's just you and the livewell you could go with a speed problem and get a lot more speed. If you're going to put two more people on the boat keep the torque prop

[@davidmcfarling8319]

If you put hydro foils on your cavitation plate it should get on plain I got a 9.9on a 14 ft v hull and I get 22 mph and also tried trimming up the motor then hydrofoils will allow you to do that which will save on gas and more weight in the bow also love your content man

[@FloBass]

Boat gets up on plane in 2 seconds so I don’t think a hydrofoil is needed. By myself I got 22mph with the 9.9. About 18 with me and the well full. But once you add another person or another 140lbs the 9.9 would only push 9mph. That’s just not sustainable for what I’m trying to do.

I've been looking at 1650's with the seat livewell, but only issue is I bait up with threadfin shad for clients, and they don't last in square wells. You need round edges and a circular flow of water. I'm hoping I can modify a 1650LW model with my well.

I can't imagine hitting a gator.....! My boat is 185 lbs. I ride with my wife and daughter, and 6 gallons of fuel and a small cooler. I'm thinking the squeak was due to loose mounting bolts and not the solas prop. I'll know soon when I retest. 11 pitch is where it's at for my set up.

Just saw it on your description, was going to say sure sounds like it's hitting the Rev limiter. You need a spare prop anyways might as well go up a couple pitches. It will probably go just as good on a longer boat. Happy guiding.

I’m talking with a few prop shops to get a better understanding of the science behind it. I’m sure it would push a 16” just as fast. I’ll upgrade the boat when I run a dozen or so guide trips out of this one.

It's definitely a good speed for what I need it to do with passengers and the well. I wont take the boat faster than 25 when I have passengers. There are a lot of long runs I'll be making when I fish alone, so I will eventually get a prop with more pitch to bring the rpm down to a better operating range at wot. It will get better fuel efficiency dropping down 500 or so rpm too.

I was going to ask about to speed, usually about the 25-26knots flat out from most outboards under 50hp down to about a 15 hp , 26 knots is about 48kph.

[@ncardaci57]

I got a 15 ft alumna craft with 15 hp . Top speed 22 . You need more weight in the front. Still a a perfect combination !!!!

[@FloBass]

I might play with the trim to push the front down, but it gets up on plane and flattens out so easily the bow lift really doesn't hinder the boat in any way.

[@victorpeirce4753]

*You need to trim the motor out as far as possible. You muricans have no idea. With just you in the boat, you only want to have the prop in the water and nose slightly raised.

My 14ft with a mid-80s Johnson 25hp hits 25. Luckily for me I traded a Mercury 7.5 for it got lucky

[@RUS_US]

1:07 ... it should depend on propeller and RPM. Put the yamaha propeller on the another motor with same RPM and check the speed again. Should be same like yamaha. 5:06 ... i.e. if your 10hp is able to give you 6000RPM then with the yamaha propeller it will give to you same speed 8:30 put some have weight on boat fwd to rise the end.

[@RUS_US]

Check this calculator: depending on prop pitch it will give you a speed www.csgnetwork.com/marinepropcalc.html

[@MountainManKm]

so you are saying a 10hp could go as fast as 25hp?

[@FloBass]

With this 1436 and a small amount of tackle I was able to go 22mph with a 9.9hp. Obviously more gear and/or another person you go slower.

[@RUS_US]

@@MountainManKm the Horse power is required to push against the water. If a hull is efficient and does not produce much drag force then you could have enough speed even from less strong motor if it has same propeller pitch and RPM. Because of that yamaha 2.5hp is twice faster vs competitors.

[@MountainManKm]

@@RUS_US I have a 15hp yamaha 2 stroke, I want to cut and weld my own exhuast, widen it, and make it bigger, mill the head just a tad, drill biggers jets and build a cold air intake for the carb, I know also depending on the height that you have the engine on the transom makes a difference and like you said your pitch and rake, I guess I just never thought about it like that. I mean I knew the hull shape mattered and I knew the prop did too, but ur right if the rpm is matched with a good hull and prop it can go just as fast. I still wouldnt believe it would be faster in acceleration.

[@graemedicks3139]

Hello Eric Enjoying your videos thank-you . After watching both this video of the Yamaha 25HP(nice power plant) and the Yamaha 9.9HP, got me throwing a few numbers about; basically cracking 30MPH easily using the 25HP (26Kts/25HP) but staying with MPH, the 9.9HP achieving 22MPH. So 60% less power available represents 27% loss in speed, not bad going, calculating one way , but conversely, a 36% speed gain requires 2.5x power increase - better displays the power required to overcome mostly a combination form& parasitic drag. Not withstanding that a different pitch may achieve more speed. In terms of power / weight and all things that "drag" away performance - How much does your boat weight empty sans engine, your own weight, fuel tank. You mentioned the live-well volume of 26gallons (98L/98Kg) knowing that with the aforementioned performance was still 30MPH, Using the 25HP, be interesting to observe performance degradation with incremental weight gain, adding weight until only 22MPH can be achieved. Curious to see just how much weight 60% less power translates into, knowing the 9.9HP can, with yourself onboard achieve 22MPH Regards, Stay safe

[@FloBass]

Hey Graeme. The 9.9hp motor was just fine when it was only me fishing. Even with the livewell full and me in the boat, I could still get 18mph from the 9.9. As soon as I added another adult passenger the boat would only do 9mph. It could not get on plane. It could only push the water out of the way adding a lot of drag. So far with the 25hp I can get it to do 27 mph with me, the livewell, and another adult passenger.

[@graemedicks3139]

@@FloBass Hey Eric, thank-you for Your reply. That is interesting - How just adding another adult, and that's the end of it, insofar as getting on the plane. Both handy little engines, but the 25HP is a surprise.Take care

[@KungPowEnterFist]

@@graemedicks3139 I have a Mercury 9.9HP (carb) on my Gheenoe Highsider. Solo (200LBS) with gear I can get 21-22MPH. Two riders (400LBS) plus gear I can get 16-17MPH. Requires a prop change, but that is super easy on these small outboards. I've known several people get comparable results on small jons with similar loading and prop change. I am not saying you should get a 10HP outboard. Just saying if set up properly you can plane a boat like this easy and get a decent speed. If I had a boat like the one in this video, its Tohatsu/Mercury/Suzuki 20HP EFI no power trim all the way and three times on Sunday. The weight difference to get that extra 5HP is A LOT. If you simply must get a 25HP, make sure to get with power trim. Tohatsu/Mercury/Suzuki 20HP and below very manageable without PT. Above that, its a back breaker.

[@graemedicks3139]

@@KungPowEnterFist Thank-you for Your reply. Good information and further backed up below, by "Takin' it Outdoors" comment' - the correct propeller is vital here, considering the lesser amount of power available. Diameter as much as pitch. To much pitch, and beyond a certain weight and she will bog down,unable to plane. It boils down to what you want to do with it. Appreciate your thoughts on power trim.

[@mikeries8549]

I've seen where ppl will attach a piece of rubber mat onto their transom to help keep the backwash out. Make it about 3 or 4 inches taller. Not rocket science. I'd love to see my 1640 hit 30 mph. We race to the duck holes on a river.

[@FloBass]

I'm looking at Xpress 1650's. I hope it will still do close to 30 with this motor.

It's super stable.

[@johncuervo3019]

If it's not held together with rivets then he could do a thirty. For 14' this boat looks really narrow. 1436?

I had a 14/48 welded with electric start and w/battery and full tank of gas would do 28mph.

[@MrDavidelliottjr]

Pitch can go up 1 or 2 more inches for more speed if u want

[@FloBass]

Definitely going to experiment. In reality I don’t need all out speed. Especially with clients in the boat. Even at 30 if I hit a gator people are going flying. Safety is #1. But I still want top performance when it’s just me.

[@wrzl1675]

FloBass the more pitch the less low end torque. You’ll windup with the hole shot of a 10 hp and unable to put much if any weight in the boat

[@wmkess]

What pitch? Factory aluminum? I”d imagine you can go up in pitch and prob go to a stainless prop. Also that motor would be best paired with a slightly larger boat imo. Something like a 1648.

[@FloBass]

Definitely need a bigger boat. I have to run at least a dozen guide trips out of this before I can purchase a bigger boat. Or if Xpress wants to hook me up, I guess I can settle for one now... 😆

[@gRosh08]

Looks great from here!

[@cameronclark5899]

Dude that’s a sweet setup

[@curtperry3364]

I put 2 , 12”x12”x12” float pods on the back of my 14ft. Flat. I have the same motor but with elec. start. It really made a big difference in the handling & performance of the boat. It also cut way down on back splash ( water coming over the transom) .

[@FloBass]

It's really not bad. I exaggerated the back splash, but it can still happen. I don't plan on sinking any more money into this 1436. Plans on replacing it have been in the works before I bought the 25.

[@floutdoorstv7914]

I have a 12ft Jon boat (tracker toadpole) with a 15hp 2stroke Yamaha, with me alone I’m getting 25-26mph. I’ve tested some different props available on Amazon and the stock 10 pitch gave me the best speed. I have lined the floor with wood and carpet but I think at most added 50lbs and I weight 220. Is that a good speed or is there anything I can do to give me more speed. I saw a guy with the same engine on a 14ft run 28mph. Engine has stabilizer tabs and I don’t know if it helps or hurts my speed. I’m wondering why my 12 won’t do 30mph. I’m thinking about up jetting my carb to get more fuel. Any thoughts? Any help is greatly appreciated!

I have a little 1972 2 hp Johnson motor on my little 12 foot jon boat and with all the fishing gear which is about 55 pounds plus my dad and I which combined is a little over 280 pounds and will go about 6-8 mph. Thinking about jumping up to a 5 maybe 7 hp motor eventually Update: got a 9.9 hp motor. 2022 Mercury

[@markanton2349]

I see so many guys doing speed test with their boats and motors that are not properly set up. You need a tachometer ("Tiny Tach") to see if you're operating within the proper RPM for maximum performance. This will help you decide if you need a different prop with more or less pitch. You need to raise the motor up on the transom so that the cavitation plate is level with the bottom of the boat or slightly above. If it blows out drop the motor a half an inch at a time till no blow outs. This applies to all sizes of outboards. Every boat that I have ever put together usually needs a different prop than the one that came with it. I own boats 10'-10hp to 34' pair of 300hp Verado's.

[@FloBass]

Ok

[@markanton2349]

@@FloBass I forgot to mention a while back you need to add one or two inches of pitch. That light of a boat and that much horsepower you should be able to hit right at 34 to 35 mph. Drag on the lower unit of a small motor at those speeds becomes critical so raising the cavitation plate up to the bottom of the boat or slightly above would really would help. Got an update?

Yes definitely go with a good stainless prop you will get a little more out of it guessing around 5 to 8 mph more . Ok I just got through watching your 9.9 video and I have watched this one before that one but I will still stick with a stainless prop . I talked my buddy into one he gets 6 miles per hour more and he is using a 14 x 48 Tracker john boat

The 3 cyl 25hp is a very smooth runner.

[@AlexLoVecchio]

I’ve been saving for a new outboard all winter. I think you sold me on this one. It’s very close in price to the 20 Merc efi I was looking at, but way faster. How’s the back of your boat sit with the 25? I have a 9.9 Honda that weighs like ~117lbs so I reckon this would be about the same at ~126lbs. I have a 14’ v with a 52” transom, so slightly wider than your 1436. Concerned about weight cause I’m kinda fat lol

[@FloBass]

With a normal amount of gear I don't see you moving slower than 25mph. Definitely get one with an electric start though. Its only $300 more and worth every penny.

[@tpainter81]

My old 1982 evinrude 25 will push my 1648 24 down river if it’s calm. 22 in waves or up river. That’s with 2 adults and 2 kids

Only 3mph slower than a Nimitz Class Carrier. Weird, eh?

[@FloBass]

LOL well when your boat only weighs as much as 1 of the bunks in crew berthing, it doesn’t seem so weird.

[@musicshuttle]

Am I mistaken or does that engine sound like it has an occasional miss? or is that caused by hitting the rev limiter?

[@FloBass]

If there's no wind, or I'm moving with the current it hits the rev limiter if I keep it at wot. I'm assuming what you're hearing is the audio clipping due to the excessive wind noise at 30mph.

[@musicshuttle]

@@FloBass ok cool, so you're not getting a miss at all, just microphone noise from the wind. Thanks so much for posting these clips, you are inspiring us former I/O guys to go with outboards!

[@cielocresp4424]

very good video a question how big is your boat

[@kipwright148]

30 is plenty. You could have a tilt and trim to get a little more but ehhhhhh. Tilt would benefit ya in the grass more than anything. For what it’s worth I only get 26 in a grizzley 15/48 with 4 stroke 25 merc loaded with gear and me. 15-20 with another person.

[@FloBass]

I don't mind the manual tilt. Its a jon boat after all. I might add electric start to it, but that's the most I want to complicate it.

Too much weight I guess. That flooding could be a real problem. It would be too much money but I've seen people install bolt on pontoons that attach to the rear of the jon to give more flotation.

If this boat was in a saltwater creek with tidal current the 200 + pound live well would have surely had a different effect.
