hydraulic lock and bend the connecting-rod.

Starter Handle
Heat the glowplug by connecting the battery leads.
Make sure that the direction of rotation of the
electric starter is correct, namely, clockwise.
If necessary, reverse leads on battery to provide
clockwise rotation.
Hang the starter belt over the flywheel and starter
and depress the starter switch for one or two
seconds. Repeat if necessary. When the engine
fires, withdraw the starter immediately.

PRECAUTIONS
When starting the engine,
the hull is off the water and
the engine is run with no
load, and with even below
half throttle engine r.p.m.
come high. Prolonged
running with this condition may result in the
seizure of the connecting rod and crank pin.
Never run the engine with high r.p.m. (never open
the throttle beyond the starting setting) with no
load (i.e. the hull is off the water).
