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 start a blocked or jammed tender as transmission
damage may result. In case of difficulty consult your Williams authorized dealer.
Recovery
CAUTION. Do not attempt to lift or recover the tender by the transom. Any stern-up
angle will cause water to enter the engine from
exhaust system and will result in serious engine damage.
Manual Override of Reverse System
In the event that the reverse servo fails a manual override
facility is in place allowing forward drive of the 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.
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.
General
CAUTION. Operate the boat with due care and at a speed appropriate to the sea
conditions. Be aware of local laws and restrictions. Always carry out a visual check of
the boat and its components prior to use. Adhere to the maintenance/service schedule.
Remove securing pin,
manually pull cable forward,
secure in forward bracket
