We've had our 1983 5 hp Suzuki 2-stroke for 4 seasons now. I didn't know about annual gear-oil service til this year, so I changed it just before a big sailing trip this summer... and the gear oil was in near-perfect condition... almost indistinguishable from the new stuff.My 1992 Johnson 8HP was only used once (1 hour) this summer in salt water.
I plan to flush and fog the engine for the winter. Based on the one hour of use, do I need to still change the gear oil?
Gear oil change is not hard. If you want to know how to do it, if you don't have a manual, send me a message. Most outboards have the same gear oil setup.Never done it before, but I will learn.
