10 M Rib with petrol inboards

[the bandit]

I know there are quite a few 10 Metre ribs with outboards or diesel inboards. Does any one know of any 10m ribs with big inboard petrols. I am having one with twin 496 mercruisers rigged at the moment and wondered how it will perform

not usually allowed to be used commercially due to fire risk.

If it is all set up properly than should be ok.

glad I am not paying the fuel bill!!!!

Sorry should of said its going to be used for pleasure and basic races.

Wondering if it will be the only one around with this set up.

I have always wondered why you don't see more like this - the petrol price I assume but big Yank engines should be quite cheap compared to diesel.

Bet it will go like stink!!!

I know the boat and it used to have a twin turbo Seatek in it, unfortunately it never performed to its potential - 496's are about 315hp if I remember correctly, so with 630hp, it won't be ultra quick although I would have thought it should break 70 ok - whether it breaks 80 will depend on the finished weight - what did Geof Hunton say?

The 496 spec is 375, & the 496 HO at 425

Thanks Matt - this senility is a pain in the arse! 750 for a pair of 496's unless they're HO's, assuming that the power is going through Bravo's, and correct C of G and the right props, it's got a chance of doing 80 something MPH I reckon - what do you think Matt?

I voiced my opinions over on Boatmad as regards speeds achievable, however I know it's a bit late but If it were me I would of been tempted to try for a deal with either Evinrude on the new 300, Yam on the 350, or Merc on the coming Verado 350, for a loan of the motors, maintenance and fuel during the race, thereby saving my capital for the race and preparation in return for advertising an outboards ability on such a great adventure secondly as far as Verado is concerned it would make good advertising in the USA for their new engine should you pull off a good result with outboard power

Any info on the Verado 350 yet???
