Important Checks Prior to Initial Use

1. Generally, a new engine has the oil and anti-freeze
removed after the works test. Fill the engine with the
correct oil and antifreeze (see sections on Engine oil and
Cooling). Check gearbox oil level - see gearbox 'Owners
Hand Book'.
2. Ensure the engine is free to turn without obstructions.
3. Ensure battery is fully charged and connected with the
battery isolator in the 'ON' position.
4. Ensure "Morse" speed and gearbox cables are fitted
correctly and that cable travel lengths are correct. Gear
selection lever - all mechanical gearboxes: care must be
taken to ensure that the remote control cable is adjusted
so that the selector lever on the gearbox moves full travel
and is brought "hard up" against its end stop in both
directions. Failure to achieve the correct adjustment will
reduce efficiency of the clutch and may cause slippage at
low revs. Warranty will not be accepted on gearboxes
returned in the warranty period for failure due to incorrect
adjustment.
5. Open the sea water cock - carefully checking there are no
water leaks.
6. Bleeding the fuel system for initial start up.
a) The fuel system must have all the trapped air carefully
'bled' out; starting at the fuel tank and progressively
working through to: the fuel/water trap, the fuel filter,
to the fuel injection pump.
b) Open the fuel tank stop tap/valve and then bleed the
fuel/water separator of air as shown in manufacturer's
literature.
c) Fuel should now arrive at the fuel lift pump.
d) Open the fuel bleed screw on top of the fuel filter by
1 to 2 turns, (see photo 18).

e) Move the hand priming lever on fuel lift pump up and
down (see photo 17) until fuel with "no bubbles"
comes out of the fuel filter bleed screw (see photo
18). The hand priming lever normally has about 90°
travel; but the camshaft lobe may block this travel
requiring you to rotate the engine to obtain full
travel.
f) Shut/tighten the bleed screw.
g) Open the bleed screw on the fuel injection pump and
again 'bleed' through to the injection pump. Continue
to hand prime for 30 seconds to push fuel and any
remaining air through the fuel pump. Clean all areas
thoroughly of fuel with tissue paper.
7. Ensure engine is out of gear and set to
see "single lever control" instructions/manual.
8. Start engine (see normal starting). Note the engine may
have to be turned over with the starter for a few seconds
before it fires. Do not run the starter for more than 20
seconds. If the engine has not started after 20 seconds
there is probably still air in the fuel system; disengage the
starter and continue to hand prime the engine with the
fuel lift pump lever for a further 30 seconds, then repeat.
If engine does not start after 3 attempts then allow 5
minutes for the starter to cool down before repeating 6 (c)
to 8. Note: The starter motor windings can be burnt out
with continuous cranking.
Warning Caution - To avoid personal injury:
• Do not try to start the engine until you know how
to stop the engine.
• Do not bleed a hot engine as this could cause fuel
to spill onto a hot exhaust manifold creating a danger
of fire.
• Do not mix petrol / gasoline or alcohol with diesel fuel.
This mixture can cause an explosion.
• Do not get diesel fuel or oil on the flexible mounts
- they will deteriorate rapidly if soaked in these.
• All fuel must be removed from skin to prevent
infection.
