Differences Between Oil-Lubricated and Water-Lubricated Stern Tube Bearings
July 5th, 2019Without wishing to state the obvious, water-lubricated stern tubes use H2O as a shaft lubrication fluid. For oil-lubricated solutions, a greasy fluid provides a slippery shaft greasing feature. These are the clear-cut differences, as plainly assigned by their technical labels. So far so good, the principal difference is right there, right in the fluid medium. […]
Marine Heavy Fuel Oil Impurities and the Effects They Can Cause to Yanmar Diesel Engines
June 19th, 2019Beautifully engineered diesel engines don’t react well when they sip on contaminated fuel sources. Sure, if the marine engine in question is a Yanmar model, it’ll probably keep right on operating, with its powerful engine stroke delivering abundant quantities of propulsion thrust, but at what cost? What kind of damage takes place inside a high-performance […]
Understanding Stern Tube System in Marine Vessel Operations
June 4th, 2019Stern tube systems are classified as powertrain intermediaries in a marine vessel’s propulsion mechanism. First comes the propeller, then there’s the sealed stern tube assembly, which links the propeller shaft to a ship’s main engine. In effect, there’s a hole in the hull for a ship’s drive shaft to reach into the surrounding water. The […]
Mitsubishi Selfjectors: What are Centrifugal Disc Separators For?
May 21st, 2019Mitsubishi Selfjectors are used on boats to purify contaminated oil streams. Think about it, the fact that fluid contaminants cause component failures. Granted, engineers on large seagoing vessels stock up on genuine replacement parts when they’re docked. They have maintenance matters on their minds. Small boat owners tend to be just as prudent. After all, […]
Compliance Level in Diesel Engine Emissions: What Makes Yanmar Stand Out?
May 1st, 2019Yanmar’s executive branch can feel the global pulse accelerating. Their directors know that they have a duty to uphold the internationally sanctioned emissions laws that are being launched right now. As a world protecting response to a recognized environmental malady, they know they have the power, the influence to make significant changes. Many large seagoing […]
