How to Detect If Your Fuel Pump Has Gone Bad

How to Detect If Your Fuel Pump Has Gone Bad

February 27, 2020

Your boat's fuel pump moves fuel to a cylinder to generate energy in the engine. When this part breaks or begins to fail, it can cause problems with running or starting your boat. Learn how to identify a failing diesel fuel pump so you can replace it. Causes of a Failing Fuel Pump of a Diesel Engine A broken fuel pump can have causes like: - Too much water getting in your diesel fuel, making its way to your cylinder and overwhelming the filter - Algae or fungi growing in your fuel tank - Dirt, water or microbes in your fuel tank getting churned…

Oil Pump Failure and What Causes It

Oil Pump Failure and What Causes It

February 24, 2020

In the early days, oil was delivered to an engine's components much differently than it is today. The first engines were lubricated with drip feed systems, which dropped oil into all its moving components, and on ships, there were workers known as "oilers" who filled up pots of oil above the moving parts. Since the beginning of the 20th century, however, internal combustion engines began using a force-feed system, in which oil is pumped around, or forced, to the engine's many parts. Engines today use a completely forced-feed lubrication system, and a critical component of this system is called an…

Engine Valves — What Do They Do and How to Correct Failure

Engine Valves — What Do They Do and How to Correct Failure

February 24, 2020

Valves are crucial pieces within the valvetrain, combustion chamber and cylinder systems of any engine. When you understand the symptoms of bad valve seals, it can mean the difference between making the correct repairs and further damaging your diesel engine. In this guide, we'll discuss what a valve’s function is, how it affects your entire marine boat engine, how to analyze engine valve failures and how you can correct the faults to keep you moving on the water.   What Is the Engine Valve? Engine valves play a critical role in the performance of all internal combustion engines. They regulate, control…

What Causes a Diesel Engine to Lose Power

What Causes a Diesel Engine to Lose Power

February 20, 2020

Diesel engines are known for their long-lasting abilities over long journeys, whether for industrial or marine-based engines. But even a diesel engine may sometimes experience a power issue. You may find your diesel engine losing power when it's hot or when it's under load, for example. If your diesel engine experiences a sudden loss of power, there are several different things that could be causing the problem. 1. Clogged Fuel Filter The fuel filter removes impurities from the gas so that they don't find their way into the engine. If the fuel filter is clogged, then it won't be able…

Efficiency in Diesel Engines

Efficiency in Diesel Engines

February 13, 2020

Is your diesel engine as efficient as it can be? The word “efficiency” has many connotations, and its meaning in terms of marine diesel engines can be tricky for some boat owners. Having a solid understanding of diesel engine efficiency will help you stay safe while extending your boat’s functional longevity. What Is Efficiency in Diesel Engines? Efficiency refers to the level of effectiveness of your boat engine’s filtration system. If your filtration is highly efficient, the filter can remove incredibly small particles from the fuel. A less efficient system may allow more particles and contaminants to escape, which can…

Reaching the Cloud Point

Reaching the Cloud Point

February 6, 2020

When you operate a boat, it’s important to keep a close watch on conditions and factors that could compromise its efficiency, safety or service life. Just as many components can have an impact on the functions of your marine diesel engine, the cold weather can take its toll as well. Colder areas of the world make diesel engines especially susceptible to these effects. If you live in a region where the temperatures drop significantly, there’s a critical condition you’ll need to keep in mind — the cloud point. What Is the Cloud Point of Diesel Fuel? The cloud point of diesel…
