How many hours?

[Who da Ville?]

I normally change out my impeller every winter, and the old one I pull out always looks brand new. I don't work for a living anymore; I just work. So, the price of a new impeller makes a difference in my monthly budget. I figure the best way to determine when to change an impeller is number of hours of service, not years.

So my question: How many hours can I run an impeller before I should change it?

Thanks!

My Yanmar manual says every 500 hours or two years, whichever comes first.

All my boats have the crank mounted pumps, so changing the impeller is simple. I check it every year or whenever I may feel it is needed. I run through a lot of bottom . I change as needed. Carry a spare.

In my opinion it all matters what kind of water you run in. Where I live there is always sand suspended in the water so I try to check it every year and change it out regardless even if it sits that long every 3.

I think this, like all other maintenance issues, will vary with boats and how they are used. I believe that owners should LOOK at the engine and all the parts regularly. Hoses, seacocks, filters, etc. Nothing hard about lifting the hatch before or after each trip. And exercise those seacocks and tighten the hose clamps. You can do it while waiting for the wife to get all her stuff together .

Are you saying the wife is slow to get on the boat?

I'll never understand why we need a bag full of stuff to go for a 1 hour ride. Get it all together and carry on the boat. Ride, get it all together and take it off the boat. "You never know when you will need something". Right.
