Note: Deep vee boats have a tendency to

“hunt” (wander from side to side) at slow

speeds with the steering wheel held straight

ahead. This is a normal occurrence and can be

minimized by anticipating boat movement and

giving a slight turn of the steering wheel in the

opposite direction.

Note: If the steering system needs repair, your

dealer has the correct tools. Do not try to ser-

vice the system yourself.

STEERING SYSTEM

The steering system on your boat does not have

a rudder position indicator. To find the rudders’

center position:

1. Turn the wheel to port until it stops.

2. Now turn the wheel to starboard until it

stops, counting the number of revolutions

as you turn.

3. Divide the number of revolutions by two.

4. Turn the wheel to port that number of revo-

lutions to center the rudders.

MECHANICAL STEERING SYSTEM

If your boat is equipped with a mechanical

steering system, periodic lubrication is required

to insure a smooth operating system.

The mechanical system consists of a push–pull

cable. This cable should be checked for proper

lubrication and alignment. There should be no

binding or looseness. Cable and attachments

should be checked for wear, rust, or corrosion,

and be properly lubricated. Check the anchor

post at the aft end of the cable to be sure it is

secure and free from rust and corrosion.

HYDRAULIC STEERING SYSTEM

Your boat may have a hydraulic steering system.

This system has four basic elements: helm

pump, reservoir, relief valve, and cylinder. The

steering wheel is mounted to the shaft of the

helm pump. Turning the steering wheel pumps

hydraulic fluid to the steering cylinder. Extra

hydraulic fluid and pressure head maintained by

the reservoir prevents air from entering the sys-

tem. An air pressure gauge on the reservoir

shows that the reservoir is charged to the

proper pressure. To keep dirt from entering the

system, hydraulic fluid in the reservoir passes

through a filter as it is flows out of the reser-

voir. A relief valve protects both the mechanical

portion of the rudder (in case the rudder strikes

a hard object) and the hydraulic system.

This is a manual hydraulic system, not a power

steering system. The effort required to turn the

wheel will increase as the system is called on

to exert more force on the rudder. At no time,

should anyone expect this system to turn as

easily as a car’s power steering.

Check the level of hydraulic fluid in the reservoir

regularly and replenish if necessary. The fill cap

behind the wheel has a gauge indicating the

fluid level. All other maintenance should be per-

formed by your dealer.

STERN DRIVE THROTTLE/

SHIFT CONTROLS

The information in this section deals with the

controls on boats equipped with stern drives.

The controls vary depending on the number of

engines your boat has. Be sure to consult the

engine and controls manuals for information

specific to the controls on your boat.

SINGLE LEVER ENGINE CONTROL

A single lever engine control operates as both a

gear shifter and a throttle for a single engine

(Figure 9.1). To shift, move the lever into the

first 15° of travel. Advance the lever beyond 15°
