Water pump drive shaft collar

[Chick]

Does anyone have a cheap and easy way to remove the water pump drive shaft collar and nylon bushing, on top of the water pump impeller? Whoever designed this one, had a real brain trust going on. Thanks!

This is on a 2003 115 hp 4 stroke.

Warm it with a propane torch and knock it right into the garbage can. Replace both parts with new, from Yamaha.

Do not loose the spring washers.

Will do. Thanks! if this collar is loose, will it cause a rattle in the lower unit?

Negative. It just holds the impeller down against the wear plate.
