Prop Install
Putting a new prop on-Anything I should do other than slide on and tighten nut? Also, I nicked the old prop and was wondering (don't think there is happened while trailering boat) but if there is a shaft issue what should I look for other than vibration?
thx

Might want to apply water proof grease to prop shaft where prop goes, will make next removal of prop a breeze...

It should be obvious, but be sure to use a stainless cotter pin too not a coated steel one or it will rust away on you.
Edit … (damn, Willy just beat me to hitting the post reply button)

If its splined Just slide it on and tighten nut and insert cotter pin, if it has a keyway line up slot on prop and continue installation...

What jmcreight said.......
There is a torque spec, but I just tightened mine relatively tight (no impact or breaker bars, just as tight as I could get it by hand with a box wrench. Note, if you have a tapered shaft, it's reccomended to use a little valve grinding compound between the prop and shaft. Spin the prop a bunch of times to let the compound "smooth" out any imperfections to ensure that it seats 100% on the shaft.

You do NOT want to be putting grease on a tapered shaft. The prop relies on the taper to stay on- hence the valve grinding compound. Test fit the prop without the key first, and make sure you get it all the way back to that point when reinstalling with the key. You dont want to be binding on the keyway.
