5 Reasons Why You Need Marine Mechanic When Boats Break Down



If you own a boat, chances are it has a diesel-powered engine and will require a marine mechanic to repair it. Owning a boat is one of the life’s greatest pleasures. Whether you have a motorboat or a yacht, you will know the peace of spending time on the water, connecting with nature and escaping from the worries of life on the land.  The following are some of the most common things that could go wrong with boats and repaired by a marine mechanic.


Problem #1: The boat won’t start. The most common reasons for this are a dead battery or a problem with the ignition system. Sometimes the ignition switch becomes loose and the key isn’t able to engage. Tightening the switch will fix the problem. If the battery is getting drained too often, use a meter to observe when it’s using too much power.

Problem #2: The boat sputters and dies. Assuming you haven’t run out of fuel, the problem is most likely a clogged filter. A simple fix is to take out the filter and clean it or replace it with a new one. If you have an inboard/outboard drive, it’s necessary to vent the engine box before you try to restart the engine. Another problem could be corroded spark plugs, which will need to be replaced.

Problem #3: The boat dies suddenly. If no one touched the kill switch and there is still fuel in the tank, the most likely explanation is a problem in the electrical system, like a tripped circuit breaker or a blown fuse. Two other common explanations are loose connections and corrosion near the battery terminals.

Problem #4: The alternator is not getting a charge according to your voltage meter. Most often the cause of this problem is a broken drive belt. It’s important to check the condition of the belt often to catch an expiration before the belt brakes and leaves you without an alternator or water pump.

Problem #5: The engine is overheating. Unlike a car, a boat has no radiator but rather depends on the water underneath it to cool the engine. If the engine isn’t cooling, it’s likely that the water isn’t getting to it because of a clog in the water intake. A loose or leaking hose could also be the source of the problem. A diesel mechanic will be able to accurately diagnose and fix any kind of engine problem.
