Prop Help

[Scotty Hendricks]

I have a 1989 Procraft 180 Fish and Ski. The prop has been replaced. It has a stainless. The problem is you cannot start off fast. You have to gradually give it the gas or it will act like a car that is spinning its tires. Then you will have to back of the gas and increase tha gas again slowly. Do I increase or decease pitch. Or where can I find out what size and pitch the stock prop was? Thanks for any help.

Re: Prop Help

The prop hub is either bad or the motor is ventilating. Remove the prop and mark the brass hub and stainess part of the prop with a sharpie. Reinstall and spin it a bit. Now check to see the marks are still lined up. if not, take it to a prop shop for a rehub. If they are lined up, the motor is ventilating due to too much trim or the mounting of the motor is too high.

This is the same motor that came on the boat. Know problems until the prop was changed due to damage on old prop. What exactly is ventilating? Thanks!

Re: Prop Help

Sounds like the hub is bad - try a different prop
