I was wondering how often you should replace seawater impellers?

i change mine after 2 seasons or every 100 hours!!!! bill

Yea, ditto here. I look at them every year and change them every other year. I am running one of the blue ones from Globe on one engine so if that one look good this winter I may keep it in for a third year.

Every season or 100 hours max for me.

I learned the hard way. It is cheap compared to what it can cost you.

I carry two spare impellers all times and replace at the beginning of each season.

AMEN!! Every year in spring.....$36.00 for two, why take a chance for less than $40.00???

I change both each spring , just so there is no doubt. Although I have been thinking on going to the "blue" impllers. Since I have been known to snag a plastic bag or two they could save me some grief. Any opinions on this?

I lost both impellers last summer and each time I replaced them with the GRW's. I did this because mine are an incredible pain in the a$$ to get to and I didn't want to have to change them every year. My temps were rock solid at 160-170 all summer, but my engines are just stock 7.4's. I got them from george at boatfix.com and I think they were right around the same price as the standard ones at West or Boatus.

Bill272,
If thats a 272 SR1 your talking about , I share your pain I've finally got mine down to under and hour each

I am impressed!! I got the second one done in around 2 hours, because at that point I knew what I was doing. It sucks when actually rebuilding the pump takes 10-15 minutes. My next boat will have some space in the engine room, because I hate having to stand on my head to do anything.
