Only 7 hours on it. Had a bad spark plug at first, ran rough. Dealer put new plug in, ran good.
But, I'm only getting 4670 rpm and 11mph per gps. I put on a 7 pitch prop, and now get 5170 rpm, but same speed.
I raised it so cavitation plate is even to hull.
My boat is 14' 218# Starcraft semi V. total weight is around 500# with motor.
Is this what's to expect from a 15hp? Very disappointing, if so.
It just seems to not get to full power.
Suggestions, experiences?
