Propspeed is a foul release coating that is designed to prevent marine growth from bonding to metal surfaces below the water line. The Propspeed system is made up of a two component Etching Primer, which bonds to the substrate and a Clear Top Coat, which provides an ultra-smooth outer layer. It is Propspeed’s unique combination of tenacious adhesion with a primer system, and the repellent of marine growth with the clear coat that makes Propspeed the leader in running gear coatings today.


The application of Propspeed gives boat owners two simple advantages. More speed. Less fuel. Propspeed will effectively protect running gear from marine growth for 1 to 2 years, requiring no maintenance. Any marine growth that does attach can be easily wiped away with a soft, wet cloth. Propspeed is different because it is slick, not toxic, and it really works!


The Propspeed system is best used on propellers, shafts, struts, rudders, trim tabs, keel coolers, bow and stern thrusters, and other underwater metal or running gear. Specify Propspeed for your next haul out!

Technical and Sales Support




Propspeed contains no copper, tin or any other toxic substances harmful to marine life. 


Should last at least a year, but many customers report two years service life, depending on the marine environment in which the boat is moored in, and how often it is used.


No maintenance needed.


Reduces the time spent cleaning, and costs by increasing speed and reducing fuel consumption.
