Troubleshooting at Sea 101: Diagnosing and Fixing Engine Problems

Have you ever broken down at sea? There’s nothing worse than the realization that something is wrong with your boat. Especially when everything was functioning fine! Unfortunately, this scenario is not that uncommon. Luckily, majority of the times it’s a problem you can fix onboard with the right know-how and a good set of tools. Even though you can’t fix every problem at sea, you can increase your chances of getting out of a pickle by knowing what to look for. With diesel engines, it is important to know that the engine mainly needs two elements. It needs both air and clean fuel in order to run. So if you are missing one in the equation, you’re going to have problems.

There are steps

Do NOT do this when the engine is hot, otherwise you could get burned. The coolant level should be within a couple inches of the filler point.

If low coolant is the problem, fill it back up to the appropriate level. If you do not have any coolant, top off with fresh water. However, once you get home drain and refill the system with coolant. Also, the coolant had to go somewhere, so check the hoses for any punctures or kinks that are preventing flow.

If your engine thermostat is high and you are experiencing a drop in engine RPM’s, check your prop shaft. Traps can get tangled and wrapped around the prop, creating excess friction.

A bad thermostat can restrict the flow of coolant even once the engine is warm. If you have a spare on board, replace it with the new one. Otherwise, the engine will run without the thermostat so remove it if it’s the culprit. Just make sure you put in a new thermostat as soon as you get home.

If your problem is due to a malfunctioning sensor, a bad head gasket, or has something to do with the heat exchanger and you are a novice mechanic, do not venture any further. Get ahold of a professional.

    As air flows to the after cooler, it will pass through a check valve that is designed to prevent any backflow, ensuring that air continues to compress and fill your tank. Backflow will damage your equipment and cause a major failure of the air compressor. Many compressor especially reciprocating compressors are fitted with pulsation dampeners, and vibrations caused by the air compressor when it uses suction and opens discharge valves. Pulsations can reverberate through the piping system, and these vibrations will make it difficult for your tools and machinery to measure air pressure and use it…

    Temperature of the water: temperature of the water can be harmful for the pipes. If the temperature is high, it can be a factor for corrosion on the wall of the pipelines. Velocity of the water: immoderate flow of water in pipelines or instant twists in pipes can cause destruction of pipes and corrosion. Recommendations: Follow prevention methods and be careful always to remain away from the problems, so that we do not have to take the help of cure, as prevention is much better than the alleviation. Rust can be the major factor for the blockage of pipelines, so they must be well-cleaned in order to make them function properly.…

    This causes a dramatic increase in hydrocarbon (HC) emissions. A car that experiences this kind of problem may not pass an enhanced emissions test. Accelerated wear may also happen if debris or rust gets past the inlet filter sock. In some cases a pump will fail if contaminants enter and jam it, causing over heating for the motor and burning it out. In another case, a weak fuel pump or one that cannot generate adequate pressure can disturb the calibration of the fuel system.…

    The boat, despite many bugs that needed to be worked out, preformed to the team’s expectations and in the result preformed well. There are many aspects to how the boat performed as well as it did and why some of the problems that were encountered were present. These aspects include the physics concepts of buoyancy and efficiency; the design choice to have the propeller bellow water and a narrower, longer body; and testing and debugging the vessel to work optimally. The vessel operated well due to the physics concepts of buoyancy and efficiency. Buoyancy works because the boat is less dense than the water causing the water to push it up causing it to float; the less density of the boat the nearer to the surface the vessel floats.…

    The circuit should only be changed when it is visibly soiled or malfunctioning. The use of passive humidifiers or heat-moisture exchangers (HME) decrease ventilator circuit colonization but have not significantly reduced the incidence of VAP. Decontaminating the mouth has become a routine to prevent VAP. Aspiration in the lower respiratory tract is treated with Chlorhexidine mouth wash or gel. Doing this reduces the odds of ventilator-associated pneumonia by…

    Early notification can help decrease the damage and life loss in the normal house fire. Flow path technology accelerates the fire when the outside air is fueling the fire causing fire spread in fuel enriched atmospheres(Madrzykowski, 2016). Flow paths of fire is determined by which way the fire wants to go and finding the quickest ventilation to add fuel from the outside air(Madrzykowski, 2016). Engaging and disrupting the atmosphere at the ceiling greatly effects the fire causing elevated temperatures to decrease. Eliminating the toxic gases and causing a disruption causes extinguishment of the fire.…
