CAUTION
Do not operate the watercraft with water in the en-
gine.
Do not try to start the engine until it is completely
empty of water; internal engine parts could be se-
verely and immediately damaged. If water gets into
the engine, follow this procedure immediately! If
water is left in the engine more than a few hours,
it will destroy the crankshaft bearings and damage
other internal engine parts.
If the watercraft becomes swamped, water may enter the
engine through the throttle body. Water may also enter the
fuel tank.
The following procedures explain the necessary steps
you must provide.
Read the summary of the procedure first and then their
detailed procedures carefully.
