Does anyone know if I can take this to my buddy's machine shop and just press the bearing back in or would it have to come out and be replaced?:mad:

Whoa... I had no idea that props could be made that way! I always figured they where cast as one piece. What brand do ya got there?

Yes. ...... but I'd certainly look at the foremath of the issue and the root cause. That said, unless you just have to get on the water tomorrow, I'd be inclined to replace the bearing, but that's just me.

How is that a bearing?

Ok so it's really a bushing... The cause was a power turn and the awesome torque of the 351 and powerslot. The prop is a Mach Master.

If I were in your place I would consider upgrading to an OJ or Acme prop. Try fixing the Mach Monster and keep it for a spare...

An excellent suggestion......even after fixing the prop, I'd worry about the hub slipping again. It would make a great spare and you'd be happy with the improvements you'll see with a new CNC prop.

Yep... I think a new one is in order. Maybe try a 4 blade. Haven't done that yet.

Talk to Eric at oj props before you make a decision.

My friend bought a 4-blade for his boat a few years ago, and really wasn't happy with it - it didn't improve performance noticeably. So, talk to the expert and see what he recommends based on how you use your boat. He may even have a suggestion for how to fix what you've got - EJ OJPROP (http://mastercraft.com/teamtalk/member.php?u=1537).

I used to have an 87 Powerslot that looked indentical to yours (Man I miss that boat). My MC dealer let me try an OJ 4 blade before I bought one and it only took a few minutes to make my decision. My 3 blade did fine, but the 4 blade was a LOT smoother and quicker out of the hole and the speed was a lot easier to hold at any speed. My powerslot was tuff, but it was a little noisey (IMO) and it got worse when I made a tight turn. Most of the noise went away with the 4 blade.

Traded the Prostar in on a Maristar 200 and the first thing I did was put an OJ XMP 4 blade on it. I believe OJ will let you try before you buy? Ask them.

Not sure what that prop is, but I have one for sale in the marketplace for an 84 powerslot:D
