his advantage. Unequal thrust is an aspect shared by all single engine
propeller-driven watercraft. A clockwise rotation propeller tends to cause
the boat, steering in the straight ahead position, to drift to starboard when
going forward, and to port when going backward. At high speed, this effect
is usually unnoticed, but at slow speed, especially during backing, it can
be powerful. For this reason, many veteran boaters approach the dock
with the port side of the boat toward the dock, if possible.
Twin-engine craft with counterrotating engines operate with less propeller
torque induced drifting, using the concept of counterrotation. One engine
propeller turns clockwise while the other turns counterclockwise. This
helps maintain an even keel by eliminating the tendency of your dual-
powered boat to veer.
SALT WATER
If boat is moored in salt water for long periods, tilt the engine out of the
water (except during freezing temperatures). After removing the boat from
the water, lower the engine to the run (down) position until the cooling
system has drained thoroughly. Hose the entire hull down with fresh water
and wipe dry.
Today’s engines are built for operation in either fresh or salt water. Fresh
water internal flushing is not normally required; however, it may be
desirable after use in salt, polluted, or brackish water. Your dealer will
assist you in securing the appropriate engine flushing device.
FREEZING TEMPERATURES
When the boat will be operated and left in the water and temperatures
drop below freezing, the engine must remain in the tilted down
(submerged) position at all times to prevent water in the engine from
freezing. When the boat is removed from the water, drain the engine
completely.
