Engine impellers

[Bottom Line]

There is a lot of discussion about changing impellers. Mine shot craps last year in the genset and I changed it myself. Several of the vanes were broken off, but with some pics that CSR member posted, I backflushed with a garden hose and retrieved the broken pieces. I bought my boat in 2006 and the engines had about 53 hours and had never had the impellers changed. I now have about 155 hours on the engines and just had them changed. I wasn't quite confident enough to try it myself...and really wasn't sure were to start...so I had the marine change them. Here are the pics of my old impellers....still in pretty good shape...no vanes missing...but a few crack developing. Anyway...thougt I would share the pics...showing both sides of the impellers.

Curious whether all 155 hours were freshwater use?

Yes...all freshwater on the same lake. The original owner purchased it new in 2003 (leftover 2002).

It looks like you changed those just in time.....

So this begs the question - how often do you need to change impellers?

"So this begs the question - how often do you need to change impellers?"

and how? Is it documented on here somewhere?
