I thought I would remove my prop and put fresh grease on the shaft just for good maintenance.
The prop will not come off. Are there any tricks to removing it?


Thanks

You can soak it overnight with zep/ wd-40/ liquid wrench etc. Try putting the castle nut back on the threads so you do not mess them up and stiking the nut with a brass hammer as you pull on the prop. Careful as gorilla blows will mess up the threads on the prop shaft. Beyond this take it to someone with a prop puller.

Hint: whenever you buy a motor ask the seller if he would mind taking off the prop , its just one indicator of what kind of maintenance the motor has seen.

Easy way to get the prop off: take it off every year and
regrease it. ;-)

Soak it in PB Blaster. Amazing stuff. I just got a lawn tractor starter apart with it that was totally frozen solid packed full of rust. Way better than liquid wrench or wd-40.

Mercury by any chance?

Do as suggested above. Tilt engine and pul on prop as hard as you can with the nut still on but lose. Have a friend wrap the nut with a hammer. This is how you remove steering wheels as well.

Last resort is to heat the prop with a torch but don't stand behind it. I have seen them shoot across garages.

Thanks for all the good information.
yes it is a Mercury, does that make a difference?

Honestly I have seen it many times and it is always an older Merc with an alum prop. My 1981 50hp Merc had one stick(1986?). My bud had a 1978 Merc 50 and almost EVERY year it would stick......hence why I asked.

Mine is a 1994 mercury 200 with a stainless prop. The prop has been on about 6 months with salt water use.

Should not be that stuck if only 6 months. I have seen them "welded" on and usually you heat the prop with a torch which melts the hubs and they come right off and you get it rehubbed. You then cutoff the old hub, etc. Yours however should come off with some PB blaster and a little elbow grease.

Whoa. That sounds unpleasant. I would not have ever imagined.
