I have a mercruiser alpha one impeller OL732338, I am trying to find a rebuild kit. I have never replaced the impellar since I have had the boat about 5 years. I have searched and searched but not sure which kit is the correct one.
Chances are all you will need is the impeller kit and gaskets. Get the OEM kit, it has all the parts you need instead of just most of them like the aftermarket kits. Part number of the kit is on the back page of this file.
