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
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
Do not leave the Dieseljet moored for extended periods as this may result in

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.

New Engine Break-in Period
The way your engine is operated during the first 50 hours of use will play a very significant role
in determining its ultimate performance and lifespan. The engine must be operated at suitable
speeds and power settings during the break-in period. Refer to Yanmar engine manuals for
information on running the engine during the first 50 hours of operation.
Fuelling
As part of its pre-delivery inspection your new Dieseljet has been fully tested and drained
of fuel. When refuelling use only Diesel fuel.
• Do not refuel with engine running.
• Remove Forward seat cushion to expose fuel filler cap (445 only).
• 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 directly hose around the fuel filler area as water
may enter the fuel tank.
Note: Boats fitted with the Yanmar 4JH4 engine are fitted with a fuel primer/pump.
This may require pumping at first use or when left for extended periods.

Before Use

Tube pressure will fluctuate with temperature. Inflate tubes in sequence to 250mB/3.6psi, starting
at the rear valves. Failure to observe this will compromise the sea-keeping ability and water tight
integrity of the boat. Inflation valves are fitted with quarter-turn locks to enable rapid deflation.
• Close inflation valves; inflate tubes evenly, starting at rear/right, rear/left, then forward valves.
• Check bilge for fuel or water contamination.
• Check engine cover latches are secure.
• Check seacock is open before use.
