YEARS. It will last till you change it again.Impeller should be change every year but not many do. My impellers have been in for 4-5 and I just bought replacements. If you run in a lot of mud and sand then change more often.
I ran my boat for 10 years before I ran it in shallow water 1 time.
This year just about everytime I go out it's low tide and I'm kicking up dirt. Jerry
Thanks. I have had mine in 10 years. Still show water out telltale just fine but I think I should check it this year. I'm thinking, order two (save some shipping etc.) so I have a spare and keep for next time.
