View Full Version : cavitation or tranny slipping?

I have a PS205 with Perfect Pass speed control. Often when I make a tight right hand turn, it feels like my boat is cavitating. My buddy things that the tranny is slipping yet my fluid level is OK and the tranny seems to perform OK otherwise. I wondered if it may be propellor cavitation or if the speed control is not disengaged maybe it is trying to speed the boat up as it slows down in the turn? Any opinions out there?

Hows the condition of your prop?
Does the boat sound differently when in the right turn?
Is there more vibration when in the right turn?

If not running in RPM mode the speed control will apply more power to try and maintain speed as the boat slows in the corner. Try running in RPM mode instead of MPH mode and see what happens.

Mine does that a little also. As you turn it adds more resistance and the PP increases to keep the speed up or in RPM mode will increase it some due to added loading. I've never considered it a problem.

I have the PP digital Pro and always use the RPM mode, also prop looks fine.

If you prop is good and and you don't have any rudder issues I can't imagine how it could be anything else but PP. You said your transmission works fine otherwise, I can't see how that would be the issue. There is not an increase in vibration or strange noises when turning hard right is there?

It sounds like cavitation, but I don't think it is.
