I didn't find any ill will in the comments. I think you will find EJ is somewhat of an expert on all things prop related for our boats. If he says you can render it unrepairable, it is so. I have experienced vibration on props that looked fine to the naked eye until we started measuring them up. I would think that trying to straighten one with a hammer would be tough to get really fixed. If you're achieving results that you're satisfied with, more power to you.

Sorry, I certainly wasn't laughing at you. Like Surfer said, just the mental image was good for a laugh. My apologies, didn't mean to offend you.

I may be a Neanderthal, but I've dinged props on boat lift and rocks and other stuff several times. If the damage is small, there's no problem pounding the bent edges out yourself. I won't be perfect but it will keep your vacation or weekend going.

When I've fixed my own props, I've taken the prop off and straightened the bent edges using a ball peen hammer (round end) and a block of wood on the back side for support. If you can get it to where it looks pretty good it will often work fine with minimal or no extra vibration. Even the Mastercraft owners manual for my '92 205 recommends this treatment. Tap carefully, no big swings, and you aren't going to do any extra damage.

If you put it back on and it vibrates, take it to a propeller repair shop and get it fixed right. You won't pay any extra for the prop repair - there's usually a minimum charge to fix minor damage and get it back to new specs. But if it works fine you've saved the $80-$100 minimum charge (or more).

Note that the advice above only applies to minor damage. If your prop is cracked, torn, or missing bits of metal then the above crude repair job won't fix it.

Maybee you guys are right. Come to think of it. Last time I was whacking my prop in the front yard(no pun intended) this lady walking her dog was looking at me like what the heck is that guy doing.

You didn't just coin a new "whacking my prop" phrase did you?

"And there I was, whacking my prop, when I notice my mother in law has been peering through the fence the whole time..."

Ha!
