Last night I had a little nighttime mishap and ran my 96' Prostar LT-1 (powerslot) into some shallow mud/reeds. There wasn't a big impact since I was idling - I just noticed that the boat quickly slowed down.

Anyhow, I was checking out the prop, which is fine, but what worried me is that the prop has a few mm of free play in it before the prop-shaft moves. Is this normal? I'm not sure if the shaft is splined or keyed. Thanks.

Your shaft is keyed. I would remove the prop and inspect the key and keyway.

Done deal. The prop nut was just loose (motorcycle guy flailing to learn about boats.) That will be my idiot question for the year, or at least today. Thanks for the help.

If it is a nylock nut, you might consider getting a new one. After removing my old nylock nut a time or two, I had the unfortunate experience of having it back off on me. Make sure your cotter pin is in good shape.

I was wondering if that was the case with Nylocks... I just ordered one, I have a rusty old nut on the end of my prop right now... PO was a real tool :-)

If it's rusty, it's not what you want. Someone posted a link to McMaster-Carr where you could get the brass nylock nut for a buck or two.

I believe I've read on the forum here that a cotter pin is not necessary with a new fresh nylock.

But why not use one. Beats diving for a prop if it backs off for whatever reason. My cotter pin was what saved my prop when my nylock backed of on my 205.
