Mercruiser inboard impeller change
On a Mercruiser 8.2L MIE inboard, I'm going to replace the impellers. They were replaced a couple of years ago, and I'm looking to replace them now before they fail.
So, here's the question. Replace just the impellers and o ring, or go ahead and get the entire plastic housing kit? The kit includes the 1 piece plastic body, impeller, o ring, wear plate, and new bolts/washers.
The current impellers haven't failed, I'm just doing a bit of preventative maint.
Diff in cost of the whole kit vs. the impeller and o ring kit is around $50 or $60.
What are the thoughts?
