Jabsco raw water pump impeller question..

[Scaaty]

350 280 Volvo Penta. AQ255A. Old Jabsco (incorrect original posting-it's a SHERWOOD) pump with bolt on pulley started dribbling saltwater on the alternator belt, flinging saltwater everywhere after an impeller change (been a month), and think a seal is letting go. Coming out of the slots in the body. I will rebuild it over the winter. I had bought a Jabsco pump on ebay, and similar, but instead of a heavy rubber 12 fin impeller with a keyway, this pump has a slide on set screw pulley, and a lighter/thinner 12 fin impeller, but its a splined shaft for a splined impeller. Anyone know where I can find one, or a part number. I have no idea what motor it came off of, but its a common raw water pump. Thanks in advance, Robby

It sounds like a Johnson pump imp ck sierra catalog, I think Indmar and some othetr ski boat engines used them

Old pumps go for $100 on ebay. Anyway, think is off a Chriscraft. I have been searching, and this site, if for no other reason, is great for identifying parts, as it has line drawings of the impellers... <br /> marineengineparts.com <br />Hey Laddie, do you have a reference to Sierra parts? I can't dig up a catalog on Google. Thought I had something if my bookmarks, but nothing. I can get what I think might be the correct part on the above link, but is $20 just to ship, plus the part, and no refund on pump parts. A Sierra P/N would be perfect,then I would have a liitle more to go on. I just might wait, and give this a "bump" during the week, as seems everybody is out boating. Thanks for the replies so far though.

Go to www.sierramarine.com it will take adode to read bot the sizes and other info are there. If you can't get it give me some sizes and I can look it up. I think once you have the number you can get it here on iboats or NAPA
