Re: Leg Oil
The service manual for my '69 55 hp "Triumph" with push button shift indicates 37.2 oz (a little over a quart) capacity for my lower unit. I just purchased some of the same lube this morning. While the label does not specificall say "Type C," the label on the front reads "For extended electric shift gearcase life," and the back label reads, "Recommended for electric shift lower gearcases used on Evinrude/Johnson Outboards 1962 - 1972.
The (Bombardier) Evinrude/Johnson part number is 775609, and is a one quart unit (946 ml.)
