Mussel Buster Propeller Protection™ is an innovative, unique, environmentally friendly, marine biofouling resistant coating system for propellers, rudders, and drive shafts. Only Matrix Coatings Corp. can apply Mussel Buster Propeller Protection™ coatings.

Mussel Buster Propeller Protection™ routinely experiences 2 years of protection, equaling the more effective bottom paints.  Since 2008, we have received dozens of reports of 3 & 4 years of life. The life of the coating will vary to some degree, dependent on the unique variables of each installation.

Along that line, some boats that typical cruise at 30+ knots, experience cavitation erosion through the coating to the base metal. Cavitation erosion is not a failure; see “Cavitation Erosion.” Our experience shows that barnacles and tube coral do not foul these areas because of the cavitation erosion. Cavitation has many differing causes and combinations of causes, but Mussel Buster Propeller Protection™ has a superior bond to the substrate, as a result it does not catastrophically fail because of cavitation erosion.

As a result of its unique technology, Mussel Buster Propeller Protection™ is not sold over the counter as a do it yourself application.  Mussel Buster Propeller Protection™ is a high performance coating that requires it be applied by skilled professionals in a controlled environment with specialty processing equipment. Matrix Coatings Corp. is an ISO 9001:2008 registered company that formulated Mussel Buster Propeller Protection™ and engineered the application process. The REAL SECRET to the superior performance of Mussel Buster Propeller Protection™ is how it is supplied, no DIY coating can match its performance.

Benefits of Mussel Buster Propeller Protection™:

1)   “Saves you money, because the wheels are always clean”-Tom Uer, 65’ Hatteras, “Jade,” Palm Beach, Florida
2)    Reduces frictional resistance of the propeller through the water by approximately five to seven percent”-Power & Motor Yacht Magazine, December, 2005 “PMY Tries Mussel Buster”*
3)    Reduces fuel consumption
4)    Environmentally friendly and EPA aquatic toxicity compliant
5)    Significantly reduces cleaning time
6)    Reduces engine loads, increases shaft RPM
7)    Eliminates electrolysis erosion from props and rudders
8)   Reduces general boat electrolysis by encapsulating major metal surfaces exposed to seawater
9)   Makes cleaning bow thrusters A snap

*Mussel Buster Propeller Protection™ has proven to reduce the load on your engines because the finish is so smooth it reduces the frictional resistance of propellers through the water.  This trait has been proven many times, over twelve years.  In December 2005, Power & Motor Yacht Magazine confirmed it in an article chronicling a summer long test on a 41’ Luhrs convertible.  During this head to head comparison of two propellers, one polished and one polished then coated with Mussel Buster Propeller Protection™, they experienced five to seven percent less engine load on the engine with the Mussel Buster Propeller Protection™ coated propeller. This was confirmed by their Cummins electronic load readouts.


The term cavitation implies to cavities, holes and bubbles, so cavitation is really about the formation of bubbles and their collapse.  Bubbles form whenever liquid boils, and boiling points have a direct relationship to pressure.  Depending on which side of the propeller we are talking about, the pressure can be higher or lower.   Cavitation bubbles can form on either the low-pressure side (suction side) or the high-pressure side (discharge side).  These bubbles can form on the suction side as low as 180°F to as high as 300°F on the discharge side.  These bubbles can have varying degrees of effects, such as: reduction in thrust, noise that can be heard when the propellers are spinning a high rpm and damage that can be seen on the propellers after even short amounts of run time.  The reason Mussel Buster Propeller Protection™ experiences this cavitation burn through is the formation of these cavitation bubbles and temperatures approaching, and possibly exceeding, 300° Fahrenheit.  Mussel Buster Propeller Coating is fused at 450° Fahrenheit, and this means that at elevated temperature the coating material loses some of its hardness.  The loss of hardness allows the cavitation bubbles to have varying destructive effects on the coating.  So, propellers with temperatures down to 180° Fahrenheit would have much less erosion, probably none, compared to a propeller that sees 300° Fahrenheit or more.  The relativity of all this is that a boat like a 31’ Rampage, with a 25 knot cruising speed, will never experience 300° Fahrenheit, but a boat like a 65’ Viking, with a 30+ knot cruising speed, definitely does experience these elevated temperatures.  The only way to make a heavy boat go fast is to throw horsepower at it.  One side effect of horsepower is heat, plain and simple.  So we are talking about 400-horsepower vs. 2000-horsepower with similar gear reductions.  This range of performance has been well documented over eight years of testing.  The good news for boat owners is that even though some boats experience the cavitation erosion, this only occurs where the cavitation is most severe.  In the areas of cavitation burn through, if the cavitation is so severe that it erodes the Mussel Buster Propeller Coating, no fouling has been seen.  Meaning, cavitation is severe enough to keep that area clean.  If it can take off Mussel Buster®, no barnacle, tube coral or mussel is going to survive there either.  Also, it has been well documented that even though a boat might experience cavitation erosion, the reduction in engine load is still maintained at approximately five to seven percent.
