Operating at Off-Idle Speeds
Unlike other OptiMax engines, this outboard is designed to
discharge water though the idle exhaust boot (located at the aft
end of the bottom cowl) when operating at speeds above idle. The
volume of discharged water increases with boat speed as a result
of the engine cooling system.
Operating In Freezing Temperatures
When using your outboard or having your outboard moored in
freezing or near freezing temperatures, keep the outboard tilted
down at all times so the gearcase is submerged. This prevents
trapped water in gearcase 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 driveshaft 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 Maintenance - Flushing The Cooling
System.
