Best type of prop puller

[Skybolt]

I'm sure @Skybolt Orlando will chime in but, if I may comment, unless there is something I don't know about, I don't like them one bit!

I know your a transmission guy and hitting anything against the drive coupling is sheer craziness. But think about the forces that the transmission takes going from forward into reverse. No matter how long you wait the prop is still spinning if your moving, think about those forces. Same goes when your backing into the slip and then through it in forward to stop the boat. That will do way more damage then any 3lb maul hitting the end of a 2"x8' SS shaft.

So here is a question that should make everyone chime in. The prop nuts are two sizes, which one goes on first the small one or the large one?

Also how do you make sure you prop is all the way up on the shaft?

Not worried about the drive coupling (guess that depends on V or straight drive) nearly as much as I am about the 'impact' to the bearings in the drive/trans.

Yep, that's what I was referring to. Just didn't explain it right. Either way if they can take the force of fwd to rev and rev to fwd I think hitting the end of the shaft isn't going to do much. The way the prop Knocker works is by sending vibration through the shaft, not by shocking the shaft/trans and moving it slightly. That would certainly do some damage.

I've watched yard guys pound on prop knockers with major force. This is a shock load that is different from fwd/rev use. On my previous boat, a yard used a prop knocker on my stb prob. Shortly thereafter, I found chips in trans fluid. Coincidence?

Also, the yard guy does not care about your trans. I've heard the yard guys say "we use them all the time", but due to my experience, and some common sense, I won't use them.

Also, I got the Strut Pro cutless bearing tool and for another $40-$50 buck you can get a plate that makes it a prop remover. It has worked great for both tasks. Wish I had brought it sooner.

And the smaller nut goes on first. The reason that you will see the big nut first is that if the nuts are stuck, it is easier to separate if the big nut is first.

I just watched this the other day and it was really interesting-shows the puller in action
