How old?
I've always treated them as consumables, A new one every season.
Say what your joking right?They make lifetime impellers and run dry impellers.. none of the shops out here sell them or will install them though. lol
That WAS my schedule as well.I change mine every other year
There was a company a few years ago manufacturing impellers out of silicone IIRC, and made the case that they were OK to run dry and would last forever. Google doesn't seem to bring them up anymore, so maybe they didn't last very long. Biggest problem I saw was that the impeller blades, especially spinning in water, rely upon the stiffness of the blade material to maintain tension and somewhat of a seal against the housing to pump water, as resistance from the water would overcome the centrifugal / centripital (I don't know the difference) force that would normally cause a vane pump to work. Making the impeller out of silicone, which is significantly softer and more flexible than the EPDM or whatever rubber Mercury uses would last forever, but it wouldn't pump water for shit.Say what your joking right?
If that's the blue impellers, they sucked ass.They make lifetime impellers and run dry impellers.. none of the shops out here sell them or will install them though. lol

Same here, 2 days per gear oil change, I do my impellers once a year, they always look like newI change mine in March and again in Aug. Also change the drive oil in every other trip. Those 2.5 cases are a nightmare imo.
Usually when I left it idle and it ain’t spitting. It’s time for a change.Same here, 2 days per gear oil change, I do my impellers once a year, they always look like new
