SECTION 2 • GENERAL BOAT ARRANGEMENT

290 Sundancer

9. DESCRIPTION OF MAJOR CONTROLS

A. GEAR SHIFT AND THROTTLE CONTROL

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.

Cockpit can ﬁ ll with water if boat is moving forward,

when it is put into reverse.

Before shifting into reverse, shift to neutral, wait for

boat to stop moving forward, then shift into reverse.

! CAUTION

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.

B. POWER TRIM UNIT AND GAUGE

The power trim allows the operator to raise and

lower the stern drive unit while underway to provide

the ideal boat angle (in relation to the water surface)

for a given load and water condition.

Trimming UP rotates the stern drive and propeller

away from the transom. Trimming DOWN rotates the

stern drive and propeller closer to the transom.

When the stern drive is trimmed DOWN, the bow

of the boat is being forces down. If the trim is in the

full DOWN position when accelerating from idle

to plane, the boat will plane faster with less bow

rise. Once on plane, the stern drive unit can be

trimmed UP slightly. This will raise the bow of the

boat slightly and increase speed. You will need to

try small differences in the stern drive position to

determine the trim position you prefer under various

conditions.
