Stuck Prop - 15 spline on 1989 Merc 80

[Greg1262]

OK, no lectures about removing the prop more often. I was doing it yearly, greasing it, etc. then skipped a year, and got what I deserved. Now, any tips for removing the prop? I have already made it unusable by busting off the flared ring on the rear end of the prop, and ground in some notches to attach a two-arm gear puller. I am going to deepen those notches, because the first attempt at using the gear puller failed, merely busting off a small chunk of aluminum from the area near the notch that I created. I have applied a propane torch to the shaft, also with no different result, and flooded the end of the splines with penetrating oil. Any other tricks I haven't tried?

Yiur probably going to have to remove the prop by first pulling the outer prop from the hub and then pulling the hub it's self, some time it will pull without heat, but some we've had to burn the rubber off and spit the hub, nice huh!

So if I burn the rubber hub until the prop can be removed, then can I use a puller effectively to get the hub off?

Greg, Before you try the puller and heat trick, put a long 2X4 between the LU and a prop blade and try to pry it off. If it is not stuck too badly, it may come off. It halps to have someone assist in holding the prop, wood motor etc.

After you get it off, use better (marine) grease on the splines, next time.
