FRESH WATER COOLING SYSTEM
The cooling system is in two parts. The fresh water, closed loop
system, and the raw water, open end system. The closed loop
system uses a combination of fresh water and anti-freeze for the
cooling medium. Beginning at the outlet of the Heat Exchanger
(16/1), the coolant flows through the hose (16/17) into the rear,
upper left corner of the Generator Housing (14/15).

Input Side – Fresh Water Pump
Bypass Tee
After circulating through the Generator Housing, it flows from
the lower front, right side of the Generator Housing,
through the Oil Cooler (2/8) in the base of the engine, to the
input side of the Fresh Water Pump (front pump 15/9).
The pump pushes the coolant across the front of the engine to
the Bypass Tee (15/17) connection on the cylinder. A portion of
the mixture goes into the cylinder cooling passages, up through
the cylinder ports (7/25) and into the cylinder head cooling
chamber.
