Those things can look just fine but if they have any grooving at all it can cause them to fail. I have replaced them thinking I was wasting my time but it ended up solving my problem as did yours. I would throw the part away *if it stoped your over heating why give them to someone who may install it to give them problems. Its always nice when its an easy fix. That Merc pump and set up looks allot like the one on my 1994 150 Johnson.

Way to go RB! I know you probably already know this, but it is wise to replace the impeller every year for salt and every 2 years for fresh water, so I've always heard.

So, didja miss a bolt at first and think it was stuck? I did that my first time. It does help to get all the bolts out before you try to remove it. ;D

You are now the official Wellcraft V20 Mercury impeller subject matter expert. ;) Where are you taking her this weekend?
