Controls and Instruments
Operating Your Tender
This boat uses a water-jet propulsion system and has unique characteristics in steering. The
throttle produces thrust from the jet pump, the directional control is provided by opening the
throttle and turning the wheel in the direction of your turn. High thrust will turn the boat sharply;
low thrust will produce less turning force. There is no rudder, so while underway there is no
steering without thrust.
CAUTION.
Maneuverability is severely restricted with reduced throttle or while
decelerating.
After running tender at high speeds it is important to allow engine to idle for a minimum of one
minute before switching off to allow turbo to cool.
If weed or debris gets caught in the jet unit during use cavitation can occur causing a decrease
in forward thrust. If there is any sign of debris or weeds etc. blocking the jet, remove the boat
from the water. Switch off battery isolator and remove all debris from around the jet unit.
DO NOT make repeated attempts to crank a blocked or jammed jet pump as trans-
mission damage may result. In case of difficulty consult your Williams authorized dealer.
WARNING.
When moving throttle/reverse control from forward to reverse, delay in
actuator movement will be observed.
Reverse system
The forward and reverse operation is powered by an electric
actuator located within the engine tray. This item requires
no servicing, but cables should be inspected and greased
according to the periodic maintenance table.
Manual Override of Reverse System
In the event of reverse servo failure, a manual override facility is
in place allowing forward drive of tender. This is by means of a
lockable pin which can be removed from its normal operating
position and secured in the forward bracket, as shown.
Towing
CAUTION.
Risk of engine flooding exists. Seacock
must be in CLOSED position when your tender is being
towed and OPEN position when tender is being used. Failure
to observe correct position could result in engine damage.
Refer to General Arrangement for seacock location.
Mooring
CAUTION.
Do not leave the Dieseljet moored for extended periods as this may result in
an accumulation of marine growth and a loss of performance.
Beaching
CAUTION.
DO NOT operate in less than 0.95m/3ft of water as debris may enter the
jet unit. DO NOT drive Dieseljet onto beach. Stop engine before beaching to prevent
blockage to pump/engine cooling system.
After beaching move boat into deeper water and rock from side to side several times to
remove sand from intake area – failure to do so can cause excessive wear to jet unit.
Trim
CAUTION.
Do not overload the boat beyond plated capacity. At all speeds be aware of
trim and keep weight evenly distributed.
Remove securing pin,
manually pull cable forward,
secure in forward bracket
