I have a 17ft sea devil with the merc 150 four stroke, this engine is very powerful and has 2 stroke like hole shot and acceleration, if the boat will take the weight would be perfect, if weight is an issue I would take a long hard look at the 115hp merc with the gearbox option - can't remember what it's called, strong motor also. Both of these are whisper quiet as well also no oil bottles to contend with.
