Stuck taking Propeller Off! Help!

[StarznBarrz]

I have a 1969 7.5hp Merc. I have the propeller nut and splined washer off (i broke the washer off) but the propeller still isnt lifting off? what should i do? ive pryed on it with my hammer, sprayed the crap out of it with WD-40 and like i said it isnt working! Any Suggestions? I have the manual but it only tells me to do the opposite of installation!!

It's apparently seized onto the prop shaft. My suggestion is to put the motor on the boat with the prop nut a little loose and run the engine. Use a jam nut or one with a nylon insert so it doesn't come off. This may pop it loose.

Then learn to service the prop at reasonable intervals, and grease the prop shaft.

just been reading this in the seloc manual it states "use heat to melt the rubber inside but be careful as the prop tends to pop off" and as stated above grease grease grease its a 10 min job..... good luck

Realize that when you do that, you are committed to buying another prop or having that one rebushed.

I think, before I did that I'd make sure I could get another prop.

Plus, a propane torch probably won't get it hot enough. You'll need MAP at a minimum.

Re: Stuck taking Propeller Off! Help!

you could try putting some break fluid on the spline it penetrates better than most things

Re: Stuck taking Propeller Off! Help!

You could make your own prop puller with chains around the prop blades attached to a two or three-jaw hub puller. Position the puller on the end of the prop shaft. The type puller will depend on the number of blades on the prop. Would also try maximum effort with penetrating fluids like PB Blaster. Never tried brake fluid. Good luck. Let us know how and what you do.

Why not take some time and put putty around the shaft and let wd-40 soak in for a few days. Lightly tap the sides of the prop a few times a day. I had this proplem years ago on an old Johnson and didn't want to spend 280 bucks to buy a new prop. By letting it soak and tapping, it came loose in about 3 days. Key word, don't be in a rush unless you got money to burn.

this is gonna sound funny but i'd heat it up and touch it with a candle, so as to melt it into the spline. theory is wax will vaporize and it gets into places that penetrating fluids cannot get into. Ed
