In the Tropics? Keep your engine running cool

Tropical conditions are challenging to marine engines. Engines require both air and water for cooling, both of which act efficiently in removing heat. However, in the tropics, the warmer air and water temperatures reduce the efficiency of your cooling system. So, what can be done?

Marinediesel takes the first step in rating your engines for the operating climate. This is one of the benefits of using Marinediesel’s VGT Series: our NIRA ECU allows such changes in rating, avoiding the sometimes large loss in horsepower often shown by the engines made by our competitors.

What can you do?

  1. Check the raw water intake and make certain that the seacock is opening / closing properly.
  2. Make certain coolant levels are topped up.
  3. Check your strainers for debris or blockages.
  4. Check your exhaust system to make certain there are no blockages.
  5. Make certain the air filter is clean and there are no blockages.
  6. Keep your fuel tank topped up. Warm weather increases condensation in the tank and thus, the likelihood of introducing water in the fuel.
  7. Make certain that the louvers venting into the engine compartment are not blocked and that there is adequate ventilation. If not, a blower may be required in extreme conditions.

All of this sounds like basic maintenance procedures, and much of it is detailed in your engine manual. It just pays in the long run to pay extra attention to these items if the vessel will be operated in harsh conditions.
