Impellers
When I winterized the engine I used automotive antifreeze with the anti corrosion additives. My impeller is going on it's 4th year. This spring plan is to do my muriatic acid flush, then run the fresh water, then replace the impeller.
I did the muriatic acid flush in Sept of 2007 just before I launched the boat. That year the boat was in the water one month, then out for the winter. So I have run 2008, 2009, 2010 on the same impeller.
That said, I don't know why I forgot to change it. I have remembered it many times and said "I have to change the impeller" and it was on the spring checklist last spring....There really was no excuse except I forgot to finish the list... forgot impeller and clean battery connections; everything else got done. Both worked fine all year...lucky.
There were 1278 hrs on the engine when I bought the boat and now nearly 1410...hour meter shows 82 hours since 2007.
My "Plan" was to take the advice of many people on here and do it every 2 years.
