Boat Diesel – Routine use

Most engines need warming up. Running them for 10 minutes or so will also charge the batteries. Then you can start your routine checks:
1. Oil pressure: check that the oil pressure light is off, the buzzer is silent or the gauge is reading the recommended pressure.
2. Check the cooling water temperature gauge: if it is higher than usual check the cooling water supply to the engine. See Chapter 4 for possible causes.
3. Listen to the noise of the engine running. If you hear anything unusual reduce engine speed, put the gearbox in neutral and investigate. Debris around the propeller is a prime suspect especially if the noise stops when neutral is selected.

If you’re running the engine continuously, make a visual engine check with the aid of a torch every 7-10 hours, taking care to keep clear of all moving parts.
