What is marine fouling?
Fouling is a kind of unwanted buildup (usually animal/vegetable derived) occurring on the boats bottom and lower unit. Fouling creates additional drag which reduces boat performance. In fresh water fouling results from dirt, vegetable matter, algae or slime, chemicals, minerals, and other pollutants. In salt water, barnacles, moss, and other marine growth often produce a dramatic build-up of material quickly. So its important to keep the hull as clean as possible in all water conditions to maximize boat performance. Special hull treatments, such as anti-fouling paint, will reduce the rate of bottom fouling. However, because lower units (outboard and stern drive) are made primarily of aluminum, be sure to select an anti-fouling paint having a copper-free, organo-tin base. The BIS Tri Butyl Tin Adipate (TBTA) base paint will not set up a galvanic corrosion “cell” as it is completely compatible with aluminum and avoids any electrolysis problems connected with many other paints.
