WARNING
The rubber seal alarm lamp warns of
seawater entering the vessel. The
watertight structure of the Sail-Drive is
dual type. Even if the rubber diaphragm
A (4, Figure 6) is damaged and seawater
enters, the rubber diaphragm B (3,
Figure 6) prevents it from entering the
vessel. The rubber seal switch between
the rubber diaphragms (3, Figure 6) and
(4, Figure 6) sounds the warning buzzer
and lights the rubber seal lamp on the
instrument panel. If this happens, stop
the engine and under sail, quickly
return to the nearest port for repairs.
