fuel consumption?

Does anyone know what the fuel consumption would be on either 15hp or 25hp 2 stroke engine?

A 25hp will use approx 8.3 litres an hour at wide open throttle.

A 15hp will use approx 5 litres an hour at wide open throttle.


The usual rule of thumb is the HP divided by a third for a carb 2 stroke.
For an opti of four stroke divide the figure by a third again. And its always per hour at wide open throttle.

buggerall...

you can spin around all day, go here go there and back again, fast and slow, donughts, jumps etc etc and it will hardly use a sniff of fuel. I have a 15hp on a 3.4 quicksilver and you are lucky to use half a 25 litre tank a day, hardly worth the worry unless you are trying to calculate how much fuel you need to do a certain distance.

not sure if that helps but they hardly use anything on such a boat

Why is there so much banging on about fuel consumption?! Unless you are a commercial user, boats are a luxury. One must have disposable income to even consider one.They cost to buy and they cost to run. Big engines burn more than small, correspondingly big boats cost more to run than small. Fuel is very expensive in the UK. My point is, in terms of overall cost of ownership and running costs the difference between a slightly more econmical 4 stroke over a 2 stroke is not worth worrying about. The servicing, marina, insurance, depreciation etc will make the fuel cost over the length of ownership pale into insignificance. If your spending money on fuel it means that the boat is being used and you're really getting some value out of it. So, if you're gonna worry about fuel, perhaps you should think of another less expensive pastime. In my opinion!

i was thinking a pair of nice 7.4 v8 inboards but the mrs pointed out they would be "cant see me girls" so perhaps a pair of 275 see me girls would be better. just thinking what i can sell to get a a see me girls, hmmmmm
