Oh, yeah, I always take the rubber impeller out of the
pump
for Winter layover.
Why do you do that? Does it deteriorate if left in?


What's the word , I can't think right now?

It 'sets' or 'takes form' if left sitting. Because the
'paddles' are 'bent'. besides, you should inspect it once a
year. And carry a spare in the boat. Mack Boring has Yanmar
parts. They make a ''spares kit'', there was one in my boat
when I got it.

You should always carry at least two spare impellers. I put one in
two years ago and it failed within ten hours - the vanes spun freely
on the hub. Frankly I don't see why people buy the parts year by
year; why not buy 4 or 5 years worth and always know you have a stash?
