thisisus Well went down after work for another shot at the evil prop. Left it last night with the wheel puller attached and a load on it. Got down and started lightly heating it...kept my hand on the shaft to make sure did not get too hot. After about 3 minutes heating it all over it suddenly popped loose. So the dragon is slayed. On to putting a new prop on and get her in the water. Thanks for all the advice and help. Really appreciate it.

jonb I had the same problem removing my prop in the winter.

I finally needed to use the combination of a suitable prop puller (I needed to modify it so that it didn't damage the prop hub), penetrating oil (PB Blaster in this case), and heat from a propane torch.

I had no luck with any subset of the above and was convinced that it was not coming off. With the above it came right off.

Faster A hydraulic puller is another option for the really stubborn ones, but still works better if you load it up and give the end a smack. Protect against the prop/puller assembly flying off by keeping the nut on the shaft.

Fstbttms Shock and vibration are part of what makes prop pullers work. Most even have a flattened spot on the tool that is a "hammering pad", if you will. They are designed to be beat on. Of course you don't bang on the prop or shaft themselves. I'd wager that I've pulled more props than anybody else on this board, all of them using the technique I've described. Never damaged anything doing it, transmissions included.

It is a rare prop that just comes right off when you apply the puller, as the OP is discovering.

sailingdog No hammering on the prop or shaft... bad idea... definitely may cause damage to the transmission...

k1vsk Contrary to some, I believe it is potentially damaging to use any kind of hammer and definitely don't "bang the hell out of it with a sledge" as that can cause damage to the transmission. I've seen yard jockeys do this often and it has always resulted in some collateral damage to the shaft, bearings or transmission which they don't care about or even acknowledge as it just means more money for them in additional avoidable work.
Heat and the proper puller is all that is needed.

lynger1 Hi just calm down
having had that problem with some other boats
just get small angle grinder with steel cutting blade grind/cut lengthwise with the shaft go just deep that you don't hit the shaft
do the same on other side and just grind/cut to the shaft try to avoid marking shaft
This Will fix it Will take you around 1/2 hour
Done

celenoglu Use a freezer spray, and use a hammer on the nut.

Fstbttms A gear pullers is not the right tool for the job. Use a real prop puller. Tension it up, bang the hell out of it with a small sledge (the puller, not the prop!) and if the prop doesn't come loose, reposition it and try again. Pressure, persistence and patience are the keys. The prop will come off. BTW, using a torch should not be necessary.
