The engine on your boat is a stern drive propulsion
system also known as an inboard-outboard engine.
This type of propulsion system has the engine inside
the boat secured to the hull’s stringers at the rear
end of the hull. The stern drive unit, also called the
outdrive because it hangs below the hull, is part of
the propulsion system that attaches to the outside
of the hull or transom. The stern drive unit pivots to
steer the boat.

The shift/throttle control unit for the engine activates
by the shifting mechanism and the throttle. The
control must be in the neutral position to start your
engine. Moving the lever forward fi rst engages the
forward gear. Further forward movement increases
engine speed and propeller RPM, moving the boat
faster. To shift to reverse, bring the control lever
back to the neutral position, then move it further
back to engage the reverse gear. Further rearward
movement of the lever increases engine speed and
propeller RPM, moving the boat faster in reverse.
Shift/throttle controls are equipped with a “throttle
only” mechanism which allows the shift mechanism
to be disengaged from the throttle. This allows
the throttle to be advanced without shifting the
transmission when starting. It may be necessary
to use the “throttle only” button in order to pump
fuel into the engine for ease in starting.
The “throttle only” mechanism may differ from one
style shift/throttle unit to another. Refer to your Gear
Shift & Throttle Manual for proper operation of this
feature.
The throttle control adjusts the RPM of the engine
and thus, the rotational speed of the propeller.
Regulating the RPM of the engine controls the
speed of the boat.
Forward motion creates forward moving water called
a “following” wake. If the boat is moving forward and
the shift/throttle is moved quickly from forward to
reverse, the boat will stop rapidly and then move
backward. The following wake continues to move
forward and can rise above the transom and fl ood
the boat.
Do not shift into reverse too quickly. Wait for the
following wake to dissipate.
