Re: Water pump gas oil mix1980 50 Evinrude
bdirect <br /><br />It's really no big deal to change out the pump, if you have the manual. Basically you drop the lower unit and replace it. But the procedure is where the manual comes in handy. Nothings gonna pop out at ya. I feel that all boaters should know how to do it themselves, as it's part of maintenence every 2 years. You can get a generic manual at the bottom left of this page that covers many models in your HP range(I like the Seloc for beginners) or a "motor specific" factory manual(Recommended) from the link below. And if you have problems when you get into it, we are always here to help you through it. The oil ratio is a 50:1 mixture.1 pint of TCW-3 outboard oil per 6 gallons of gas.<br /><br />
