Prop 'pop' always a surprise!
 
I know the prop is gonna 'pop' off of the tapered shaft with a puller and a little heat, but everytime it does, and I know it's gonna happen..... but it sounds like something just broke real bad:) Keeping the nut on a few turns is key to preventing a big problem!

This time I followed this post and lapped the shaft/prop and it's a noticeble difference even in the feel of the fit when installing the prop. When there is a good surface-to-surface contact - you can feel the difference. Checking mine before lapping I had a pretty high area.

FYI - Prussian Blue by Permatex isn't available in NAPA, Grainer, or any parts store in my area. Even called the machine shops and engine builders and no luck. I used a large Sharpie and it worked great.

You don't have amazon prime?

Anything like that I just get shipping in 2 days for free off amazon.

I don't think you so much need Prussian blue unless you want to see it, you can just lap it regardless and then fit the prop. Prop is softer than shaft.

In general, I avoid Amazon - just a personal thing with me. But you are correct, lap it for 5-10 minutes and it's gonna be a good fit. The sharpie worked great though. Local machine shop recommended that, or spray paint.

alright... help me out here... what is "lapping" or "lap" - my old prop came off easy and new one was snug - I did get some prussian blue...

inquiring minds want to know... :)

A little CCOCD thread on prop fitting - interesting in his statement that the taper, not the nut or key hold the prop in place, hence the need for a puller to remove.

After reading this - how many replacement props have been installed without this process.... ;) thanks for the CC thread direct.

Tens of thousands, easily:) Prolly every inboard prop installed at the factory and 99 out of 100 replacements!

Always cool to cruise through the other forums....FYI, thread author had a really cool shaft alignment video:http://www.youtube.com/watch?v=3_w0LvD6gEc
