Operating in Freezing Temperatures
When using your outboard or having your outboard moored in freez-
ing or near freezing temperature, keep the outboard tilted down at all
times so the gear case is submerged. This prevents trapped water
in gear case from freezing and causing possible damage to the water
pump and other components.
If there is a chance of ice forming on the water, the outboard should
be removed and drained completely of water. If ice should form at the
water level inside the outboard drive shaft housing, it will block water
flow to the engine causing possible damage.
Operating In Salt Water or Polluted Water
We recommend that you flush the internal water passages of your
outboard with fresh water after each use in salt or polluted water. This
will prevent a buildup of deposits from clogging the water passages.
Refer to “Flushing The Cooling System” procedure in the Mainte-
nance Section.
If you keep your boat moored in the water, always lift the outboard
so the gear case is completely out of water (except in freezing tem-
perature) when not in use.
