Does anyone have a 7 blade w/p impeller in there zilla? On page 4-12 of the quadracer manuel they show a 7 blade impeller but when I try ordering one from the dealer they say it is not available. Yet there is one on page 4-12. Does anyone know where to get one of these? I think I could get better circulation with one of these!!!!

 

Three Zilla's in my group, 1987, 1988, and mine 1989.
None of them have a seven blade water pump impellar...

 

just a note- better or faster circulation of the coolant doesn't mean better cooling. take the thermostat out of a car and they will overheat in hot weather or hard driving situations.... it's there to slow the flow down & regulate the temperature of your motor by allowing time for the coolant that's in the radiator to cool before it goes back into the engine. most quads don't have a thermostat or anything that slows flow down much... if you look into the radiator while it's running, it'll be flowing plenty fast.
