Yamaha 150 4 stroke max revs wot

Hi. Looking at a ribeye 650 sport with a yamaha 150 4 stroke. On a test it only rev'ed to 4100 which was 29kts.

I would have thought it would go a little more. What revs could you expect at WOT and speeds (assuming a clean bottom which this one didn't have)

Any info on fuel consumption at cruising revs (I was assuming 3000 ish) would also be helpful.

Thanks

I've got a Ribeye 600 with Yammy F115 - I get WOT of around 5500-5600 and top speed of around 35-37knots on GPS (dependant upon load). I would imagine your WOT to be around the same (maybe higher) with top speed of around 40-45ish? Don't forget that the prop size/pitch will have an effect too (mine is a 13x17K).

Can't say I've accurately measured consumption but it doesn't seem to drink it!

Just click on the relevant engine and it gives you the WOT range.

Hope this helps.

That sounds way low. Is the hull clean? If it is, I'd say it's way over-propped. Any idea what the prop specs are?

It may also be blocked injectors, an electric/plug fault, fuel system blockage, any number of things really.

Forgot to say - welcome to the forums!

Is the boat kept afloat?

If the bottom is heavily fouled this would be the first thing to get the seller to deal with.

Ribeye's are the best!!!

Hi Sealion, I purchased a 2008 Ribeye 650s with an F150 engine this February and love the boat so good choice of boat

My boat is heavily anti-fouled which is rough as its patchy but with a 19" pitch prop I get 5700 - 5800 RPM and a top speed (according to yam gauges) of 42 - 44 knots so there is definitely an issue with that setup you have just sea trialed.

The 19" pitch prop is the setup recommended by Ribeye / Yamaha.

I did quite a bit of research on these boats so if you need any advice or other questions just pm me

Good Luck

Thanks for all the info. I think the boats got lots of weed on the bottom. After checking out the service history (or lack of) and cost of a retube I decided against that particular boat. Put an offer in on a pascoe sr7 instead.

Thanks again

Hi do you know what the fuel capacity is on a ribeye 6.5m inboard tank. Plus have you been able to fit a reserve engine (outboard). Cheers
