pontoon motor cavitation, HELP!!!!!

KennyA · #1 June 18th, 2006, 03:49 AM

I have a 21 foot pontoon with a 60hp mercury on it. Does it really matter what position the motor is on a pontoon as far as performance? It blows out in one hole, but seems to lose a couple hundred rpms in the next lower hole. I recently put a transducer on the left pontoon, would this cause it to blow out?

Thanks ,

Kenny

It is not cavitating, Kenny. It is ventilating.

Keep it down where that does not happen. The couple hundred rpm you "lose" are only pushing bubbles, anyway.

Ditto what JB said.
