Marine Diesel Engine Overheating Under Load

Marine Diesel Engine Overheating Under Load. Overload is a leading way to shorten the life of a diesel marine engine. Dialing down the rpm’s may allow the engine to recover and run well at a more leisurely pace.

When the temperature goes above 200, start getting worried. Running engine under load over the long haul negates the very real concern of abusing a diesel. Overheating from excessive load will show up only at higher throttle settings.

The previous owner had told us that the kubota engine, adapted for marine use, would overheat above 1,800 rpm in the summer. Running at too high a speed.

Marine diesels should run at 180 degrees fahrenheit. However, you can make some specific arrangements to add load to the engine that will help the engine and utilise the load for productive purposes.

I am suspecting it is combustion related and could be a fuel injection problem or a timing problem. Overheating may occur when a marine diesel engine is run at high revs for an extended period, which puts systems under more strain than they normally encounter, exposing latent weaknesses.

Overheating can also be caused by a worn or damaged water pump impeller. Test this by letting the engine warm up, then running the engine at full throttle while in neutral.

We are asking for a lot from the main engine but the load profiles show we’re not over loading it. Test this by letting the engine warm up, then running the engine at full throttle while in neutral.

If you can’t, make changes. The starboard engine works fine, but at 2000 rpm the port engine overheats.

Coolant Leaks Are The Primary Cause Of Overheating In Diesel Engines And Can Be Easily Identified, As You Will Notice Either A Low Coolant Level Or An Excessive Amount Of Bubbles In The Coolant.

It is particularly a problem with 4×4 and light vehicle diesels. Check your manual to find out where the bleed point is. It's a matter of how the engine has been run (and maintained) in an overall sense that determines it's longevity.

And, For Sure, Ensure You Can Always Exceed Rated Rpm At Full Throttle In Gear.

When the temperature goes above 200, start getting worried. If you can’t, make changes. Several factors can cause overloading:

A Typical Marine Engine’s Raw Water Circuit.

This can be a result of engine components, such. Overheating may occur when a marine diesel engine is run at high revs for an extended period, which puts systems under more strain than they normally encounter, exposing latent weaknesses. Once the temperature hits 200f, i slow down to prevent damage and everything returns to normal.

Overloaded weight on the boat; If you can get a load profile, it’s worth asking for it. Running engine under load over the long haul negates the very real concern of abusing a diesel.
