Knowledgeable brothers,
With some encouragement from here, I replaced both raw water pump impellers a couple weeks ago. Removed the pumps completely and replaced which, as you all suggested, was THE way to go on this job!
It went well, water is pumping nicely. I noticed some scoring on the front pump cover plates but nothing too bad. My only issue is a very slight drip from one of the cover plates now. I cleaned the surfaces well and used a new gasket along with some aviation permatex (non-hardening sealer).
What do you suggest for a fix? Wrong sealer? I always liked the aviation permatex but maybe this wasn't the best place to use it??
I thought the scoring on the cover plate would not cause a leak as it is inside of the sealing surface. Am I off base on that assumption?
Thanks all!
JD
