Yesterday when pulling a rider out of the water, the boat would take off as normal and then it would momentarily "rev up" and feel like the shaft is spinning but the prop wasn't. This would last a second or so then return to normal. It did it a few times, and we came home. Today, we had a group with us and it started doing it again, only worse. I went to the dock, pulled the boat and changed the prop. Different prop, same result. Called the dealer, and he said it sounded like cavitation. Sounds reasonable, but with two different props?
Background - it's a 2007 Outback. Memorial Day weekend I dinged our prop. Stock prop is an OJ 13x13, we took it and had it refurbed. I also bought an OJ 13x12 from Skidim, for better holeshot. This is the prop that I had on yesterday that first started "slipping". So today I figured maybe it's just not the right prop and changed it out with the original 13x13, but it did the same thing. Once I told the dealer that it was doing it with two separate props, he said we may need to look at the rudder or shaft. I don't mind taking it in, but I wanted to check with you guys to see if it was something I was overlooking. I've never changed a prop in my life, so part of me is second guessing if I even put the props on correctly. If they aren't "positioned" correctly, can this cause what I'm experiencing? I basically put the key in, slapped the prop on and tightened it until I couldn't tighten anymore.
I need to note that this is the 4th time I've taken the boat out with the new prop, and yesterday was the first time it acted up. The first two times it ran flawless, even weighted down with quite a bit of weight. Since it first did it yesterday though, it has gotten progressively worse until we took it out.
Any ideas are welcome. I plan on taking in to the dealer on Monday just to give it the once over unless something is figured out by you guys. Thanks in advance!
