Bottom Paint Outboard

We moor Channel Surfing in brackish water, (salt and freshwater) at the mouth of a river. ​

​

Bottom paint needs to be re-done every 2-4 years, depending. Having a covered slip keep sunlight off the waterline and helps prevent growth enabling the paint to last longer. 

​​

We bottom paint the transom bracket and nose cone of the Yamaha with Trilux 33. Do not use a copper based anti-fouling paint on the outboard.

Also note, the outboard, being aluminum, is not compatible with a copper based anti-fouling paint. Use Trilux 33 on the outboard and leave a 1 inch gap around the transom bracket to separate the two dissimlar anti-fouling paints.

Aluminium and copper in an electrolyte such as salt-water will cause galvanic corrosion to occur. Seahawk Cukote on the fiberglass hull, Trilux 33 on the aluminum transom bracket and Yamaha F300 nose cone.
