Re: How often to change impeller?
Just had an discussion with a friend who changes impeller every 5 years. (about 500 hours) says never had a problem...
I change every year and will continue to do so, even though I
have to remove water pump to change.
Very bad feeling to have an impeller go and motor overheat, happened a few years ago while coming into harbor alone, between 2 large jetties, with no wind, light opposing current and large ferry bearing down fast. (Port. Jefferson, Long Island)
Oh forgot about the nasty, widespread thunderstorms expected within the hour.
Actually was a new impeller that the vanes parted from the core,
but figure odds are in my favor changing every year.
I always keep a spare aboard.
Not to leave you hanging, if any interest, on how I made out that
afternoon. Would love to tell you about my intrepid seamanship
but the truth is...
As I was attempting to turn boat away from oncoming ferry, thinking as I readied the anchor, would my anchor and short scope keep me off the jetty when the wake of the ferry past within 20-25 ft ... I looked over my shoulder, within hailing distance was a SeaTow captain coming in for the day.(First and only time I have used my membership, but worth it) Like always to be independent, but also like to use all resources available. Within a minute was under tow and was anchored before the weather came, thinking
all in all, that day I had no complaints.
Change your impeller early and often as one never knows.
