advice re outboards

Hi have been looking around for a RIB and have seen a Ribtech that I am interested in it has a 135hp 2.5 V6 2 stroke outboard. Is this engine going to be thirsty or what is it likely to cost me to run fuel wise and servicing, thanks

Easier to answer the question knowing the length of the boat.

Compared to cars all outboards are thirsty!
2 strokes are particularly thirsty.

That engine will be burn 50L of fuel per hour if you give it the chance. How thirsty depends on fast you want to go, the load, the boat, the waves, the driver etc.

I can't comment specifically on servicing but IMHO everything marine is expensive, on top of which most marine mechanics are associated with main dealers which keeps prices high. I'm not aware of particular brands being more or less expensive, with the exception of the E-tecs with their 3 yr service interval.

If it's a 135 Optimax, then it will be more economical than the carb version. A 135 Opti on a 6m(ish) RIB will cruise at around 1.2nm/litre. Full pelt would be around 0.7nm/litre.
Annual servicing should cost 150 - 200.

I had one (merc 135 2 str) on a 5.8 that never burned anywhere close to that, was a lightish boat mind you,.. but that sounds a bit heavy to me

Thanks for the replies it is on a Ribtech 585 that is advertised here

any comments gratefully appreciated. This is the sort of set up I am looking for but just a bit unsure about the engine don't want anything that is going to be to expensive to run.
thanks
