Here you are Propeller. This slightly above my normal cruise of 3000 rpm which nets me 50 mph. That is where I get the optimal mileage. Above or below that the mileage drops. Above that , you must keep in mind replacement parts are expensive and I know my pockets aren't bottomless
I do believe the issue is more of getting rid of a certain type of boat , namely the go fasts. Next it will be the cruisers because of their wakes , then the jetskis(at least the 2cycle ones). Next it could be you , so be careful what you wish for...you might just get it
.
As far as me not coming to Winni...not till they ban powerboats. But then again I'm also an accomplished sailor (but don't let that be known on the "Marine Mafia" site).
