Still in my 1st season of owning first big boat. It's in heated storage now.
I wanted to inspect/change impellers for next season so I pulled the whole water pumps off for access. It's the only way you could get at the Stb. side. And that was after removing the fan belt cage. Once you have the pump in hand you can change the impeller although this isn't exactly an easy procedure either (but I did get it).
If I have a failure underway my thought is to have a spare pump ready to throw in. Questions: Is it ok to let the impeller sit in the pump over long periods of time? Do you change your impeller seasonally? Would it be ok to install the impeller now with launch not until mid May? It does seem like these Sherwood impellers are manufactured well but what is the life? My impellers appear good after about 1 season and 225 hours. What do you you lubricate the impeller with at installation? Vaseline? Dish Soap? On your first start after spring launch is it sufficient to just make sure the raw water strainer is full of water or do you have to prime the pump. Looks like there is a plug on these pumps that could be used for priming.
Appreciate the feedback as always.
