Been away for a bit. Back at the ’58 CD-15 rebuild. Scraping around the Web and happened upon a water pump complete kit rebuild, #0763758, though not in the parts manual or Marine Engine, etc. Any thoughts appreciated. I think there is a caution on metal or plastic impeller housing.
Yes, it is a valid BRP replacement water pump kit. Now this is the smaller impeller with a plastic housing and a metal core liner. Once you switch to this kit, you must use the smaller impeller. Not knowing what your old water pump looks like, I would just install a new impeller kit #379764. I hope this helps!
