Re: 1967 chrysler 3.5 hp model 3701 outboard
The gearcase has two screws at the side. Upper is level and the lower is fill/drain. Use EP 80/90 gearoil. Fill from lower and up.
Normaly Chrysler OB use mixture 50:1 but this 3,5Hp has a watercoold leg and an aircoold powerhead. Because of this and that the pistonbearing is a bronzebushing instead of rollerbearing the mixture should be about 20:1.
