Great choice, your skiff seems to get up on plane nice. How did you manage to get electric tilt with the tiller for the Yamaha? In the US it seems to only be available with remote option…
Depends in numerous factors including dry weight of boat, trim set and wet weight (including all bags in boat etc..). A 40 hp on a jon boat goes much faster than on a 16 ft boat. Also, it depends whether the boat is rivited or welded. Rivited boats are quite a bit lighter.
It also depends whether it's 2 or 4 stroke. 2 strokes are lighter than 4 strokes and can attain higher speed and rpm. They are also lighter, but less fuel efficient. However, both have evolved quite a bit and are in high demand.
Hey sorry for the late reply. F50 is a 4cyl so more capacity which equals torque although I was really impressed with how well the 3cyl F40 went. It’s a lot lighter as well which will be a consideration if you are going with the tiller version. I like to always go max HP for the boat when possible which is important with the yammies if you plan on running a heavy boat as they don’t have a super strong hole shot. Great reliable engine though.
I've only recently fitted it however first impressions are very good. It runs very quiet and smoothly. Power delivery is typical fourstroke but still quite strong strong. Fuel consumption seemed good but as expected (it used 10-12 litres over 2 hours at varying speeds from idle to full throttle). The tiller design is great - one of the best around.
Simon Hall thank you Simon for informations,i have boat selva tiller line 4,8m 280kg,i still expecting my engine f30 efi tiller. sale person said it comes vith 12G propeller.what you think is this too big for this boat? ,because im going too use it almost time with 2 persons on board,,thank you again Simon.
Yeah I don't think so and it didn't feel or sound like it was spinning that high? I think the limiter is set around the 6,000rpm mark from memory and if it was hitting the limiter it must be a soft one because you couldn't feel it come in if it did.
Robert tophan I'd go with the Yamaha. I've owned the current 40 Merc (was a new motor) and it had some quality issues (paint peeling off) that I attributed to it being made in china. Performance was line ball with the Yamaha 40
What an engine. Sounds lovely.
I think i have found the motor for my 4 m sea sprite . Thanks for the post

Nice Nice and the sound is great.
I'm getting one for my 399 stacer proline. What boat is this on mate? Thanks for the video 👊
Could you tell me diameter and pitch of the propeller? Thanks!
old post I know but does the engine run smooth at idle and midrange .I wonder in the same hp range would the 4cly be smoother .Thanks
very nice!
great video! what speeds are you getting in your boat?
you get about 33 mph. I would say 35 tops

Hello! What kind of screw do you have in this motor ?
Artur
Artur Budziński do you mean propellor? I
@@SimonH2O yes, what's the size? Amazing holeshot and top speed that you have!!
Please, I need to know prop size. Mine has 15 and seems to underperform. Total weight, boat, engine and passengers is 550kg.
Stainless steel or nickel plated
Hello mate,
Any reviews or advice on the Yamaha F50?
Unsure whether to put the F40 or F50 on my new boat. $800 extra for the 50

Are you hapy with engine,and how much is fuel consume? because my plan is to bay same engine like this 30hp?thank you

Will she turn up to 6400 rpms

you can take out one piece and that motor turns up like 6400 and it will flat go
Yum
notice any difference between this and the merc 4 stroke?
Robert tophan the Yamaha was smoother and quiete. Much better tillerr handle also.
Simon Hall was the Yamaha faster as well?
Robert tophan yep by about 9 kph on a bigger boat although the Merc was only a 30 so not unexpected
Simon Hall would you go with this or the merc in 40 HP?
Robert tophan I'd go with the Yamaha. I've owned the current 40 Merc (was a new motor) and it had some quality issues (paint peeling off) that I attributed to it being made in china. Performance was line ball with the Yamaha 40
Can show the lifts
