You can get 5 yrs easy on these. Marketing say fewer, thats all. I got 20yrs/1800hrs on my first Alpha one, it did not failed, just set and lost some flow..

Does anyone have an opinion on this impeller?

At my marina they have recommended to change after 3 years in fresh and 2 years in salt. I do plan to change mine this year. I changed the impeller in my 75HP Merc outboard last year; not sure how many years it had been because I've owned her for 3. My guess is that it was many more years than 5, the wear plate was shot...
Thank you, Patrick

My FIL's Yamaha is going on 12 years with the OEM impeller.
I will be changing this year........I think.
