    Pull out old impeller with an impeller puller, saves a lot of cussing. Take the old one out coat in Vaseline/silicon spray insert it into a ziploc bag and put it in your glove box with a new seal in case you have a failure on the water. Take the one that was in the glove box and put it on a shelf to show how many you have changed. I will never understand why you would try to save $40 on an impeller that is the heart of a cooling system on a boat that you will expect to run perfectly all summer. I guarantee most of us spend more than that on the first Beer run of the summer. Put a new one in EVERY year and pinch pennies somewhere else.

    I would go by hours versus seasons. I average about 40 hours a season, so I changed mine after season 2.

    If I was running 200 hours per season, I would do it annually.

    Only way I would do this is if you pull it out at the end of the season and re-install at the beginning of the next. I still prefer to put in a new one every season. I have had one rip a fin off because it was left in all winter and run again in the summer (run hours were less than 50 for 2 seasons). After I found that, I replace it every season, seams silly to pull it out only to put a used one back in. $40 impeller can save a $60K to well over $100K boats.

    I inspected the impeller when winterizing and most times they lasted three seasons.i carried a spare impeller as everyone should do anyway. If you had a catastrophic failure of the impeller on the water (very low probability), you need to know that you can still run the boat on plane to get back to your launch site. The impeller does nothing when the hydrostatic pressure is high such as being on plane.

    I use a puller, remove it for winter and use it one more season. After two summers it gets replaced.

    If you guys are removing or inspecting your impeller each season, you really need to install a new crush gasket to prevent any sort of leaks as those are 1 time use gaskets. Just a heads up to keep an eye on it.

    Agreed. When I was a kid we had an impeller disintegrate. It took 2-3 trips before all of the rubber pieces were flushed out. The boat overheated for at least two trips. It is a cheap piece of mind for me. Letís face it. If we can afford these boats, we can afford a $40 impeller.
