Does everyone replace the impeller every year?
I take it off every winter season and I check whether the cracks, if not put into place until the spring of old and period of the season. I have never yet been broken up about. 200-250 hours a season, or a total of 400-500 hours earlier, this was my boat volvo twins. I can not say the quality seaboard seamax impeller my tug, experience in just a few months.

Of course, I have included a new imeller and seals, and a good puller, quick work.
