Emergency procedures
If the engine stops
1. Check that the fuel supply valve (if fitted) is in the open position.
2. Check the fuel pre-filter (if fitted) and the fuel filters for water. If a warning light for water in the fuel is
fitted, and it is illuminated, water has entered the pre-filter. Water must be removed before the engine is
operated. Drain any water found and fit new filters.
3. Check the amount of fuel in the tank. If the engine has run until the tank is empty, there may be dirt or air
in the fuel pipes. Change the fuel filter, see section 4. Fill the tank. Eliminate air from the system, see section
4.
4. Start the engine again. If the engine still will not start, check that the cables and contacts of the stop
solenoid are in good condition.
If there is a reduction in engine speed or a loss of power
1. Check that the propeller is free of debris.
2. Check that the induction system is not restricted and that the engine compartment has a good supply of
air.
3. Check that the fuel pre-filter or the fuel filter elements are not restricted or contaminated by water. If a
warning light for water in the fuel is fitted, and it is illuminated, water has entered the pre-filter. Water must be
removed before the engine is operated. Drain any water found and fit new filters.
If the warning lamp / audible warning for high coolant temperature operates
Warning! Do not remove the filler cap while the engine is still hot and the system is under pressure, because
dangerous hot coolant can be discharged.
1. Reduce the engine speed to idle. Stop the engine if there is a leakage of steam or coolant from the
engine.
2. Check that the coolant level is correct after the engine has cooled.
3. Check the seacock and strainer to ensure that there is not a restriction to the supply of water to the
cooling system.
4. Check the raw water pump operation. Check the impeller.
Note: Coolant leakage can be stopped temporarily with adhesive tape, hose and hose clips.
If a high-pressure fuel pipe is broken or has a crack
Warning! Ensure that fuel does not spray onto the skin. Stop the engine if there is a leakage of high-pressure
fuel.
1. Stop the engine.
2. Remove the broken pipe from the engine.
3. Connect the end of the pipe that is not broken to the fuel injection pump. Put the broken end of the pipe
into a suitable container.
4. Operate the engine at a reduced speed on the remainder of the cylinders. Empty the container at regular
intervals.
If leakage occurs from a low pressure fuel pipe
Temporarily stop the leak with a hose and hose clips.
If leakage of lubricating oil occurs:
1. Stop the engine immediately and try to find the cause.
2. If the main flow can be reduced, put a suitable container under the leakage point.
3. Fill the engine with new lubricating oil at the same rate as the loss of oil and frequently check the
lubricating oil pressure.
