Just returned from our 1st trip of the season and had a little mishap while putting the boat on the trailer. The prop nicked the trailer and is now slightly bent on all four fins. We don't have a replacement prop and figured now is as a good time to purchase one. What size prop do I need? Where is a good place to purchase one? We plan on getting the one we have now repitched and use it as a backup. Thanks for your help!

The wakeboard prop is a 14.25 x 14" OJ XMP prop, with LH rotation, a 1/8" shaft diameter, and a .090 cup. They are not cheap at about $500-525...

I dinged mine at the end of last year and had it re-done. It was $250 vs $500 + for a new one

If you load the boat straight, it doesn't hit the trailer, but when you load the boat crocked and the front eye misses the boat buddy and your wife keeps going sideways in front of the guide poles, the prop ends up hitting the trailer! She did good to kill the throttle as soon as it hit so the damage is real minimal.

Cal is right on the WB prop. You will notice an immediate difference in pulling power, holeshot, etc. My wife did the same thing to our boat on our second outing so I feel your pain. We had the dinged prop repaired for $100 and have it now as a spare and bought a new WB prop for about $400. I think I have heard some people talk about skidim.com for the best deals on props. I got mine at my Supra dealer in Dallas.

Robert, I've been there before too. It sounds like you might be backing the trailer too far into the water... make sure the top of the wheel wells are showing out of the water! Good luck with the prop.

If the trailer is put in the water at the right depth it's impossible ( no matter who's driving the baot) to hit the prop. I see it all the time, most peopel don't know how far to put a boat trailer in the water. Guys that have been boatting for years...
