Verify that battery connections are tight
2. ENGINE TURNS OVER BUT DOES NOT START
- Check fuel level

- Check fuel line for air lock
- Verify that fuel pump solenoid is not stuck
3. ENGINE THROTTLES UP, BUT STALLS AFTER FEW SECONDS

Check that pressure regulator / unloader switches to by-pass mode
4. ENGINE SPEEDS UP, BUT WATER DOES NOT GO OUT THE ZERO-

Ensure that the power unit is not located too far above the water level,
exceeding the capacity of the feed pump

Check that feed pump inlet water strainer is clear
-
Check for leaks in the water lines
-
Check for an air-lock in the water inlet lines

Pump mechanical failure
Pump drive belt failure

Check that pressure pump inlet and discharge valves are not stuck open
(common problem if not flushed after use with sea water)
