Impellor Replacement - 4.3L Merc

bigdog · 01-14-2008, 10:41 PM

I am way overdue in changing my impellor on my Mercruiser 4.3L.
Would like to do this myself in the Spring, when getting the boat ready before
the first launch.

I am fairly mechanical, is this a easy DIY replacement for a back-yard mechanic ?

Not really sure where the impellor is located, but I suspect part of a hose
connection to the engine. I suspect that if I am removing a hose connection, new gaskets should be used when re-assembling.

Any help would be greatly appreciated.

Thanks.
