Question re replacing seawater pump - Maxum Boat Owners Club

SeaPuppy: I know you have done this before, so I am hoping you can give me some info. I need to replace at least the housing cover for my sea water pump and I am thinking about replacing the whole housing. (It is the same one you had on your 2700).

I was given this part number by Mercury, 862914T10, to replace the whole thing, but I cant tell if it comes with the pulley wheel attached. Do you know? If not, how did you replace yours? Maybe I need a gear puller? thanks

nope..doesn't come with the pulley attached..you need to get a pulley puller and pull it off the shaft..then have it pressed back onto the new one....

it's not that hard with the right tools.....

I need to replace the housing cover becuase it has score marks worn in it which could allow water to travel backwards, but I am not sure I need to replace the entire housing. The other side has some score marks against the back wall but no possibility of water back-travel. Somebody told me the impeller rubbing against the circular score marks could conceivably aerate the water. Any thoughts on that? Since I do not have the equipment necessary to replace the pulley I am hoping I can just get away with replacing the cover side of the housing only.

hmm...never heard of score marks aireating the water ....possible I guess :shock:

take the housing and pulley too an auto machine shop..for about 10 bucks they will press the old one off and then press the new pump onto the pulley....it's not hard and if the right tools are handy quite fun......
