Gas mileage for 90 HP Yamaha 2 Stk.

[marbra]

Can someone give me an ideal of what the gas mileage would be for a Avon Seasport 545 with a 90 HP 2 Stroke Yamaha. (1994 boat & engine)

Thanks,
Mark

Mark hi, our club rib uses the 85 hp premix version of this engine on a humber 5.5m We recon on about 1 litre per mile at 18 knots with 4/5 divers and kit. With a bigger prop and less weight I would think the boat would eb capable of 25 knots but the fuel consumption would be similar.

Thanks Pete, that's about what I thought also.

My 90hp Mariner 2 stroke on my 5.4m Searider uses about 0.9 litres per mile - generally only run with 2 up but tend to be doing 25+ knots.

Usually Yamahas are less thirsty than Mercs & Mariners. 1 lit/mile for this boat is more than the average. But if you want to be on the safe side you may do your calulations with this consumption.

One litre per mile for us
