Anything special about removign a bronze 2 blade prop from a bronze shaft I should know about? I'm planning on doing it this weekend using a standard gear puller. Thanks, jv

Don't lose the key....
There is a little rectangular bronze key that fits in the slot on the prop and mates it to the shaft. It fell out and dropped to the bottom of the slip when I pulled my prop. If you're on the hard it's no big deal but in the water it's easy to lose. Any prop shop will have a replacement if you do lose it.

Pulling the prop
Loosen the nut but leave it on the shaft. Put the tension on the puller, then hit the prop bushing from behind with a mallett/hammer. The nut will stop the prop from flying off the shaft.

Derek, Your method works well but I would add
this idea. After applying tension on the puller, strike the head of the bolt on the puller itself. Once the puller has good tension on it a small tap on the puller center bolt will spring the prop off faster and earlier than striking anywhere else. I always use a brass hammer when using any one of my different pullers. Striking anywhere else could damage parts you want to keep. The measure of tension on the puller before rapping is a good strong pull on a 10" box end wrench while holding the prop in your free hand. If it doesn't spring lose then re-tension and rap again. Repeat until it pops loose. If you over tighten the puller bolt trying to free the prop (without striking the center bolt) you will cause the puller center bolt to start to go sideways and ruin the puller and screw up the prop shaft threads. The time spent getting the puller set up equally on all legs is what makes this job easy and doesn't ruin expensive parts. Ray S/V Speedy
