Im 95% sure Im going with a Mariner 60 2-stroke now. I don't want to put any more than 60 on it, but I want the best performance I can possibly can within my budget. It's not like a 60 is going to drink that much fuel anyway even if it is a 2-stroke (compared to a 115 2-stroke anyway!)

Tim

My 4.8 had an etec 50.
Did 32 knots (was swinging a rather large prop) didn't use much fuel
Was a superb boat but would have been superberer (arf) with an etec 60.

Happy shopping

Thanks Robin

Have had a look at e-tecs but I think they're out of my budget.

Tim,
My sailing club has a Raider 4.8 (Same as the Ribcraft 4.8) with a 50HP Mariner 4stroke (not efi), tops out at about 30knots and feels like it needs more power, ideal for a rescue boat though.
Ribcraft have fitted several with 75HP ETECS for skiing although I think they have been sold to employees.
I had a friend with a 4.8 powered by a 60HP Mariner EFI 4stroke, very nice combination, did around 35 knots and extra economical. I have found the EFI 4strokes to be more responsive than the older designs still running carbs such as the Hondas. A 60HP 2 stroke would be lively, how about a Tohatsu 50 TLDI (direct injection, do they do a 60HP variant of this????)

60 two stroke would be perfect!

I agree ... 60hp would be ideal. Last year I had a go in a demo Ribcraft 4.8 with a 75hp. The acceleration was awesome, but perhaps a little over powered for day to day use.

I got a Mariner 60 2-stroke in the end. Took it out for it's first test run yesterday and got 32 knots out of it. I think it needs raising though as there was a lot of spray from the lower leg.

You should be getting substantially more than that. The Uni rib with a 60hp 4 Stroke BigFoot Mariner (big heavy engine) I have managed to get up to 37.5kts, with just me on it.

What sort of revs are you pulling?

Not sure (no rev counter yet) but we certainly weren't hitting full revs.
