I have a Volvo Penta AQ290A and it needs the Jabsco rubber impeller replaced. I have searched everywhere to get a definitive answer on a part number. There are so many to choose from. Anyone know what I should get or where to look?

Look up just above your original post and click on Volvo Penta Parts

Follow the links to your engine and raw water pump.

Thanks for the link. Now we have two part numbers according to Jabsco. One has 12-blades #22120-0001 and the new part number is #18777-0001 but it has 10-blades. Which should I get? Is the 10-blade preferred for some reason?

You get the one for whatever pump you have. One of those impellers is thicker than the other. Only you know what you have, and being as old as it is, it may have been replaced. That is when you have to replace your impeller with what type pump you have.

Wrong. One is not thicker. Both are the same length, diameter and same 5/8" bronze splined shaft. The only difference is the amount of blades. One is 10 and the discontinued 12 blade which you can still find online at most places. So again, what are the pro's and con's between the two?

Well I spoke with Jabsco and their Tech Rep said 12-blade equals more flow. So I ordered the 12-blade.
