Stopping
Twin-engine craft with counter-rotating engines operate with less pro-
peller torque induced drifting, using the concept of counterrotation.
One engine propeller turns clockwise while the other turns counter-
clockwise. This helps maintain an even keel by eliminating the ten-
dency of your dual-powered boat to veer.
Stopping (checking headway) is a technique that must be developed.
Since a boat has no brakes, reverse thrust is used to slow and stop
the boat. The momentum of the boat will vary according to the load
as well as the speed. Make it a practice to slow to idle (no-wake)
speed before shifting into reverse.
Twin-Engine Maneuvering
One thing to keep in mind when
maneuvering with twin-engine
powered boats at low speeds, is
that turns are made by thrusts of
power from the engines and pro-
peller, not by turning the outdrive
unit; this means at lower speeds,
steering your boat becomes a
combination of propeller direction,
engine thrusts, and steering wheel
maneuvers.
To make sharp and close quarter
turns, observe the following:
●
Before attempting to make close turns at low speed, bring the
throttles to idle so you can shift into reverse without damaging
the engine.
●
Reverse the direction of the engine on the side you want to turn.
For example, if you want to turn starboard, shift the starboard
engine into reverse. The forward speed of the port engine, along
with the reverse rotation of the starboard engine, will pivot your
boat into a starboard turn.
●
Practice using the throttles to control the boat. You should try
these maneuvers in open water before attempting them near
docks or other boats.
●
Use quick “bursts” of throttle to control the boat. Keep in mind
that once the boat starts to move, momentum will carry through.
It is best to learn maneuvering skills in open water away from traffic.
Adequate practice is the only way to develop your boating skills.
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.
