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.
If weed or debris gets caught in the jet unit during use cavitation can occur causing a decrease
in forward thrust. If this condition is allowed to continue the engine may overheat resulting in
serious damage. 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 your tender if it has been blocked or jammed by debris or
rope as engine damage may occur. In case of difficulty consult your Williams authorized
dealer. (A full list of authorized dealers/engineers is available at williamsjettenders.com)
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.
Towing Valve
CAUTION.
Risk of engine flooding exists. Towing valve fitted.
Valve must be in CLOSED position when your tender is being
towed and OPEN position when your tender is being used. Failure to
observe correct valve position will result in serious engine damage.
Mooring
CAUTION.
Do not leave the Sportjet 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 0.95 m/3 ft of water as debris may enter
the jet unit. DO NOT drive Sportjet onto beach. Stop engine before beaching as
damage to pump/engine cooling may occur.
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 could cause damage to jet unit.
Trim
CAUTION.
Do not overload the boat. 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 schedule.
WARNING.
For the safety of passengers, do not use rear facing seats above
15mph.

New Engine Break-in Period
Consult your BRP engine operator's manual.
A break-in period of 10 hours is required before continuous operation at full throttle. To achieve
a good break-in, a maximum of
3
/
throttle should be observed, however, brief acceleration and
4
speed variations contribute to a good break-in. Williams suggest that after the first 10 hours of
operation, the engine be checked by an authorized BRP/JPS ROTAX marine engine dealer.
The break-in period is very important and must not be neglected.
Fuelling
As part of its pre-delivery inspection your new Sportjet has been fully tested and
drained of fuel.
•
Ensure ignition is in OFF position.
•
Remove seat cushion to expose filler cap.
•
Re-fuel in a ventilated area.
•
Do not overfill the tank; be careful not to spill fuel.
•
Tighten fuel cap securely after re-fuelling.
•
Open engine hatch and inspect bilges after re-fuelling.
•
The filler cap has an integral breather.
Do NOT hose around the fuel filler area as water may enter the fuel tank.
Minimum Octane Rating
CAUTION.
Do not use fuel from fuel pumps labeled E85. Use of fuel labeled E15 is
prohibited by US EPA Regulations.
