"Hey all,

does anyone know how the water circulates in 60ESL70D Johnson?

Is it kind of a "closed loop" with a small pee-hole in the lower gear case? So that once the cooling lines are full the same water (minus just relieved off the pee-hole) circulates through the engine?

I'm just trying to understand what I see. I'm a novice at this.

Thank you."
