1974 Johnson 50hp?

[Texas Prowler]

Well I'm gonna order a lower unit kit. I have left the outboard sitting in water for a week now and have a tiny drizzle of water coming from the fill hole. The oil is thick as corn syrup and brown so oil and seal replacement is due. I'll probably change the oil twice to flush out the old stuff...water impeller comes in tomorrow. I guess i could start taking the lower unit apart now.

Should i run dextron through first to flush out the old oil then go with the new?

Well no more water then could fit onyou index fingernail. Also the pressure test held. Looking at the lower unit the bolts holding out to the mid section look brand new.

My '74 Johnson 50 uses Champion UL-77V plugs. They are a surface gap type plug.

Well guys I put in a new water impeller kit and changed the LU gear oil. All went great! The old impeller really didn't look bad. I fired the motor up after swapping both and it stayed warm to the touch after the t stat opened up. I'm ready for the water...
