Systems and methods for containing and delivering protective materials to raw water passageways within liquid-cooled marine engines

A marine vehicle having a raw water liquid-cooled engine, said vehicle comprising:

• a raw water passageway for conveying raw water into association with a liquid-cooled engine that is carried upon the marine vehicle to absorb heat generated during operation of the liquid-cooled engine;
• and
• a protective system coupled in fluid communication with said raw water passageway of the liquid-cooled engine at a location along the raw water passageway downstream of a raw water intake port of the fluid-cooled engine, said protective system capable of delivering a protective material to the raw water passageway and said protective system further comprising a reservoir that contains a protective material and a dispenser that controls release of the reservoired protective material.
