Antique Outboard Friends,
As an addendum to this project, I was curious about the water circulation pattern on these engines. The bulk of the cooling water enters on the throttle side, circulates through the power head and exits on the shifter side. I did notice a small, machined passage, shown on the attached photo. This would allow a small amount of the return water to exit into what I’ll call “shaft alley”.
Can anyone tell me the purpose of this feature, as it applies to the water circulation scheme? I’m continuously impressed by the smart design features of these ’50’s vintage engineers in their products. Slide rule guys knew their craft.
