NOTICE
Always return the engine throttle lever to the
extreme low speed position before shifting.
NEVER shift the unit while engine speed is
above 00 rpm.
E - 4 UNDERWATER EQUIPMENT
(Inboards)
Avoid running aground or striking a
(submerged) object. Serious damage to the
engine(s) or inboard underwater gear can
result and the boat can take on water. In the
event of such an occurrence, proceed at low
speed to the nearest service facility and have
an immediate inspection made of the prop
shafts and struts before further use of the craft.
Keep all life saving devices at hand while
driving to a dock area. If the boat cannot be
immediately removed from the water,
thoroughly inspect the bilge area for leaks
so that the boat does not sink while moored.
