Safety Check; After Use - Williams DieselJet 445 Owner's Handbook Manual

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 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 directly hose around the fuel filler area as
water may enter the fuel tank.
Note: If engine is fitted with fuel primer/pump it 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 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.
•
Set valves to shut and 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.

Safety Check!

WARNING. ALWAYS attach yourself to the safety lanyard when engine is running.
Before setting off as a precautionary measure always test lanyard for its functionality by
pulling away from its seating – engine should always stop.
WARNING. NEVER operate the boat when bathers are using the boarding ladder, risk of
serious injury exists from reverse deflector.
WARNING. NEVER investigate engine bay with engine running or ignition on.

• Ensure all passengers are correctly seated.
1 Turn on battery isolator.
2 Run bilge blower for 4 minutes.
3 Secure any loose ropes that could get sucked into jet unit.

Warning Lamps/Alarms
CAUTION. Risk of engine damage. In the event that a warning lamp or buzzer activates
during use, STOP engine immediately, investigate cause and refer to engine manual.
Contact your authorized Williams Dealer.

After Use

To prolong life it is very important to wash entire boat with fresh water after use and prior
to storage, especially the jet pump area. Failure to carry out fresh water washing will
significantly reduce the life of underwater components. Check anodes routinely.
•
Wash jet pump
•
Check bilge of boat and dry any residual water
• Rinse footwells with fresh water
• Isolate battery
