Cool. Big fuel consumption?

I've only ever owned a 40hp . But 1to1 sounds ok. It has a 100 l fuel tank.

That would be my guess is efficiency is similar to my old 2 stroke 115 - typically over a tankful mine would be about 1.1 to 1.2 litres per mile when topped up after a typical run.

re 130 yamaha

hi

i had a 6 mts rib with this engine on , i had the boat for 5 years and it never went wrong its a good engine but is heavy on fuel
the boat is now on the isle of man, i found out last year the club has done nothing to the engine for 5 years not even a service and its stilll starts first time and runs ok.................

if u are useing the rib a lot may be a rib with a 4 stroke engine would be better would be about 50% less fuel

i went from this yam 130 to a 100 hp yam 4 stroke what a difference in fuel and as a diver no more 2/stroke fumes when picking up divers

thanks

steve

I would debate that if Cam is spending a lot of time razzing around at WOT. Bottom line is that to get 115HP, you need to burn a certain amount of fuel. At WOT even a 4- stroke will drink. Might be a touch less eficient at turning the results into CO2, but will still need to burn approx the same amount of fuel to get the power at the prop. If lots of rescue / pottering at idle, yes, a nice new EFI 4 - stroke will substantially reduce fuel consumption as they are way more efficient at idle.

Not going to argue with that!



As a general observation, if the rib is going at a good price, why not live with the oil burner for a while until funds are avaialble for an upgrade? - IF you even need to upgrade it...
