Yamaha 25 horsepower 4 stroke 2020 review and jon boat max speed

[@knightcustombuilds6988]

2003 25hp Nissan/tohatsu. Over the years ive built it out. It pushes my 1519 Duracraft 38mph. Its a single coil two cylinder two stroke. The weight is fairly low weighing around 115#. Finding that balance between weight and output.

[@ACPro]

Very cool!!!

[@drornavaro]

You can always remove the trim rod (tilt pin) while in shallow waters keeping the tilt lock lever in the down (lock) position. This way the outboard can be raised up and down without getting locked. Just ride slow and watch out from engine rising out of water while in reverse.

[@malibujoe01]

I got an 2018 E tec 25 hp evirude short shaft electric starter. It is attached to a 1448 Tracker grizzlly all welded with myself and one other fat guy it will do 27 to 28mph! That's also with a 55 lbs minn kota bow mounted trolling motor and one very large AGM battery and humminbird helix 7.

[@n0llie]

Got the same motor! I run it pretty shallow too, around sandbars. So I agree the manual tilt is a bit cumbersome. Another thing I’ve noticed is the mounting clamps come loose fairly often. Not sure if this is common with clamp style mounts seeing as how this is my first outboard, but I definitely can not complain!

[@ACPro]

I had to tighten mine up a few times too.

[@omieyouknowme]

Tighten clamps then zip tie them together.

[@davidb8397]

I had a 25 mercury, I used to lock the mounting clamps with a padlock, that will keep them from loosening and will prevent theft

You can remove the mechanism that will disengage the auto shallow water drive. It will allow you to manually set it.

[@TheMightyBluegill]

Does it have any kind of friction adjustment for steering? My Honda has a little lever that you can increase the friction so that it doesn't go where it wants if you take your hand off the tiller for a minute. It's super handy.

yes it does and it is nice to use when trailering you can keep it from swinging

First thing I would do is change fuel filter. If you haven't ran it much change the gas and add seafoam to the tank. Start with the basics.

I worked at a dealer 10 years ago . Got the most complaints on these little Yamaha 4 strokes, customers would shit their pants on performance loss vs weight

Any regrets on the lowe boat? Great set up. Best value for fishing fresh water anywhere on the planet in my opinion. entire boat not to heavy and seems like plenty of room. Been looking a long time and have settled this combination is the the best value. not sure about the boat brand.

[@ACPro]

I actually looked for this boat. It is rivet boat . Not thick ga aluminum. And low cost . But!!!! My friend had one 20 years ago the 1448 big Jon and it made a believer out of me. It has a big advantage over the heavier boats. It is much faster. And the draft is almost nothing. This boat will go in inches of water . It is amazing how shallow it will go and also extremely stable. So this is my reason for getting it. If I was buying a jon boat again. I would buy the same one. That front seat is just the cats meow!!!

Good I ask you a 40hp and 30hp Yamaha how much come out long leg 4tienpos of those new or used. Thanks I'm from Uruguay. If you have any phones we make it graci

[@jamestown12345]

I don't think they sell this version in that market, they do sell the 20hp version but not the 25hp version for some reason(you may be able to order the f25 version from the distributor). If you need a 25hp motor get the Yamaha Enduro 25 which is a lot older technology and uses pre-mixed fuel but it is reliable. Don't get the 25 BMHS (S / C) unless you need the safety lanyard. The f20 may be a better choice than the 25 BMHS (S/C) if you can't order the f25 and you can live with 20 hp. If you're planning on taking it into the ocean and the boat can handle it get the enduro 60 or 75 (also uses premix). For a larger panga get the 75, for a smaller one use the 60. If you only need 25 hp get a 25 enduro that wasn't used commercially.

[@ACPro]

No idea

[@Garh.pandit.415]

Engine book kaise

[@JohnJohn-tf4cr]

Listen..!! This F20 Yamaha as more than 362 cc like was the previous ones till 2020. it's now got 462 cc and the displacement is worth to see , because now you can maximise your propeller to the max with a big pitch. and you have the same motor as the F25 witch is also 462 cc. Amazing stuff again as you can convert your F20 to a F25 by changing the computer Box and the spacer

[@omieyouknowme]

Sorry the 20hp rating is at the prop at 5500rom, the tohatsu 20hp is almost 30lbs lighter. 20hp out of a detuned motor is kind of throwing money away. Rather get a motor maxed for displacement. The ECU for all these little motors is mitsubishi.

[@JohnJohn-tf4cr]

@@omieyouknowme I would say that the volume * V=TT X r2 X h * push of the piston at 462cc is worth the money. If you do compare the other 20 hp at lower cubic engines witch explain the lower weight of the unit .* I do understand that *. Nevertheless, the power generating the output by compression, is a big help, when the capacity of the boat is in average + load again. I say that the pitch of the propeller this time is more respected with a 462 cc by constant energy content. * Piston stroke in feet = Propeller revolutions * at 5500 rpm by extrapolation. And by changing the ECU, which is controlling the amount & timing of fuel intake, Cannot be done without enlarging the air intake, for a proper conversion to achieve 25 hp. Don't even think enlarging the air intake by keeping the same ECU as it would overheat the pistons having to much oxygen.

[@omieyouknowme]

@@JohnJohn-tf4cr I understand that there is no replacement for displacement, the yammie per site says is 432cc btw. I'll verify with service manual. As for prop size, yes you are swinging a slightly larger prop on yammie vs the tohatsu, but the motors are rated at shaft hp at 5500 rpm in the prop. I would love a comparison in the same boat by someone, see if the extra displacement and weight affects anything. Take the yammie vs lighter tohatsu and Suzuki which both weigh under 100lbs in bare short shaft trim.

[@JohnJohn-tf4cr]

@@omieyouknowme Mmmmmmm....ya , The weight of the motor as to be consider, in this matter. Yammie's are heavier to carry for & on, that same Boat in a speed test. Ohhh ya ...Resistance is the name of that game. Lighter Boat = heavy motor = Lighter Boat Yamaha does have the power at 432 cc but any sort of resistance, is questionable. As is the water spreading or the shape of the boat, is never gonna give us an answer. I understand that 432cc as the power indeed, but i do have a SHAFT to consider. hahahahahhhahahahahahha...........!!! As for Connecting Rods on a motorcycle indeed. I do have my F20 / 2021 on a 16 1/2 aluminium boat. Having this 432cc is a good move,. Nevertheless if I want to consider using all of it, Ill have to change the ECU and air diameter intake. Tanks Man. You make my day

[@omieyouknowme]

@@JohnJohn-tf4cr I ran the f25 when it first came out, with just me after the motor warmed up it lost almost 500rpm. Yamaha would not believe me, so I made you tube videos. Took the cowl off and had the extra 500rpm back. They eventually reflashed my ecu I'm curious if run the motor first thing in morning, then at mid day when it's warm, do you lose rpm as well? My solution was I actually cut a hole in front of the intake, 3d printed a ram air snorkel for it. Of course sold the motor right after as I got a screaming deal on a 40hp.

[@cameronmaryjr.4226]

I had one of these motors for about 2-3 months and one day I went to go start it up and it wouldn’t go. I took it to the dealer and after a month they came back to me and said that it was the wiring harness. I got a replacement motor and I’m supposed to get the boat back this week. Hopefully I didn’t get another lemon.
