Re: Correct gear oil for mid 1950’s Johnson

Well I’ll be darned, I just looked in an old OMC Accessories catalog (1978) and sure enough, that is what it says. But that isn’t what I remember. I would have thought for sure that we used HiVis in everything except Electric Shift at the dealership where I worked back in those days. But there certainly wouldn’t be anything wrong with using Premium Blend either. After all, that is the only thing OMC made, before introduction of HiVis. But maybe my forgetter works better than my rememberer.

Anyhoo, we all know there is no difference in non-electric gearcases that spanned the period before and after 1972. HiVis was introduced when they started coming out with high horsepower motors and the heavy load they put on gears. To me, that makes it better, and what I would use.

Or, you can do what the manufacturer says.
