WD-40 and a paint can opener pops it right out.

First year owning the boat so replaced mine this fall...couldn’t get the impeller slipped out so unbolted the entire pump (3 Allen bolts on engine pulley and 1 on the “holder”)

I also found removing the entire pump easier and allows more room to get a grease gun on the rudder zerk fitting. I use 303 to free the impeller, coat it in Vaseline and put it in a zip lock for the winter.

I've used both Vaseline and silicone grease and didn't see any difference in impeller life. Main benefit of removing the impeller from the pump is to relax the fins.

Remove impeller, coat with a thin film of Vaseline and store in an airtight bag is part of the winter layup procedure in the Indmar manual that came with my boat.
