ENGINE COOLING WATER
Opening or closing the cooling water system
of the engine driving the Sail-Drive is done
by the cooling water cock fixed on the upper
case of the Sail-Drive. Be sure to open the
cock (Figure 5, (1)) and confirm that the
cooling water has suction by cranking the
engine before starting the vessel. The
cooling water passes through the Sail-Drive
case, cools the engine by the cooling water
pump, and is then discharged.
