Re: Evinrude impeller replace 1985 15hp
Great link. You can switch gears to whatever works best. The only comment I would add is to be very careful that the water tube goes back dead center of the water tube grommet on top of the water pump. If it doesn't it will cause an overheat and you'll have to do it over. Best of luck. Rick.
P.S. an 85 isn't an old Evinrude. It's just broke in.
