If you have an outboard ( or fro that matter inboard ) engine that has
been in storage for a period of years. In my case a brand new Volvo
marine engine that had set for 2 years. The impeller may have died
of "dry rot". For what they cost it help to have a spare around the
first time you start such an engine.

Nice idea, wish it was mine. The volvo has an analog temperature 
guage but you don't see the problem until you're miles from home
and hot.
