250 or 300hp Ribeye?

Hi, excuse first ever post if this has been done to death - I am about to buy a Ribeye 785 with either the 250 or 300hp Yamaha. Does anyone have any experience or thoughts re performance, fuel flow, handling etc. Boat will be used for charter operations. Thank you

I'd suggest you search for ribnet opinions and then make clear whether it is just the engines you want feedback on, otherwise could be bit of a bun fight.

Thanks, and Yes I guess I'm really just interested in which engine works best on a 785 - or is there in fact not much difference in the two?

Hi,

I too have just ordered a Ribeye 785 (having had a couple of Ribcraft) but with the 300hp. It's basically a re-tuned 250 so weighs the same and shouldn't affect the handling too much. On part throttle which is what you'll probably use most of the time the fuel consumption should be similar.

What colour are you getting ? I've gone for the all grey.

Test drove the 300 - v impressed - looking secondhand so considering a 250 as I've seen a few about. Wanted the confidence that the 250 is man enough!

I would guess 250 will be enough on a 8 meter rib!!

We had 225 (2 stroke) on a 7.5 meter and it was a good 48 Knot boat all day long. i have no experinence of the hull you are buying but i guess in real terms you are not really going to notice the difference in performance between the 250 and 300hp.

It maybe a bit more efficient but this is always a tough one because if your anything like me, the more horses you have the more you use them!!!

if you are loading the boat up with lots of people or weight then maybe the extra gg's will help but depends on your type of use!

There are only two reasons why a 250 would be preferable to a 300 if the hull is rated to 300hp, weight and cost. If they weigh the same, that only leaves cost. As for performance/economy, the 300 will obviously out perform the 250 in terms of acceleration and grunt, top end would be determined by propping. The 300 may possibly be more economical, as it wont be working as hard most of the time, or the difference between the two wouldn't be worth worrying about.

225hp/7m = 48knts is pretty meaningless. Which 225, which 7m? Every combination will give a different result.

As the OP is looking to buy second-hand, I'd suggest the buying decision includes more variables than just hp.

I thought the OP had already bought one, as his/her profile shows Ribeye 7m+/300Yam

It must be a fairly new one as he older ones were only supplied upto 250 hp
I had a 785 with 225 4st good for 50knts lightly laden but did chine walk at the top end

I did think it must be a heavy boat if the op wanted to put 300 on it for a 785 .... so if a 225 made that hull chine walk (if its the same hull just uprated) and its now got a 300 on it .. with paying punters in it/renting it
