I own a fiesta pontoon, i just put a new motor on it a johnson 50 hp. when i first mounted the motor i bolted it on on its lowest setting. i was a little dissatisfied with it as when i was running wide open a wall of water would shoot up off the transom, when i tilted the motor quite a bit of water drained out. it eventually shorted out something reducing the RPMs to nothing more than a rough half-idle. i then mounted the motor to its highest setting but now am having problems with cavitation, and there's still a little too much water rushing upward for my taste. i'm considering getting a stationary jack plate for it, hoping the 4 inches the motor would be offset from the transom might alieviate that wall of water rushing up into the motor. I need to get this figured out as my passion involves salt-water, and all that salt on a powerhead will kill it before ive even broken it in. would an offset jack plate make sense? Would getting a jack plate with a greater offset be even better? i dont have any experience with jack plates and dont want to throw anymore money away. So if there's anyone in the know how, let me know.
