Just so people know why a Marine engine is so different than an industrial or an on the road engine. This is an intake valve out of a 22-year-old Yanmar Diesel that is being overhauled in our shop. As you can see, there is severe pitting in the valve. All the valves in the engine are like this. This valve would not have lasted much longer before the stem broke off and it destroyed the entire engine. People wonder why overhauls occur? Well it’s more often in marine engines. This is just part of the reason; the salt air is very corrosive and causes excessive premature wear on all parts of the engines. The other reason is extended run time at a much higher RPM depending on the vessel type, or excessive load on other types. Always keep up on your maintenance and have more in depth inspections done as they become older in age. Thanks, Carter

Stuck injector on a Detroit 12V71TA, sticking injectors on some 2 cycle Detroits can destroy an engine with a run away condition. If you have a Detroit diesel in your boat, that is a two-stroke and it has been sitting for a long period of time AKA many years. Please make sure to have somebody that knows Detroit’s look at it before trying to start the engine. It could save you a lot of money and a lot of problems.
