Propspeed Application FAQs
What Is PropSpeed and How Does It Work?
PropSpeed is a two-part foul-release coating that creates an ultra-slick surface on your propellers, shafts, and other underwater metals. Marine growth can't grip it, so it slides off when the boat moves. It contains no biocides, copper, or tin. The coating lasts 12 to 24 months when properly applied by a trained applicator.

How Long Does PropSpeed Last on a Boat?
ypically 12 to 24 months, depending on how often the boat runs, water conditions, and application quality.
Boats that get used regularly see longer coating life because water movement keeps the surface clean. The coating degrades gradually. When it stops feeling slick to a diver's glove, it's time to schedule a haul-out for reapplication.

Is PropSpeed Better Than Antifouling Paint for Props?
They serve different purposes. Antifouling paint works on hulls but gets stripped off spinning propellers and adds unwanted thickness to precision blade surfaces.
PropSpeed bonds chemically to metal, holds up under rotational forces, and keeps the blade profile smooth. The two work best together: antifouling paint on the hull, PropSpeed on the running gear.

Does PropSpeed Actually Save Fuel?
Yes. A coated prop delivers more thrust with less drag, which means lower fuel burn at the same cruising speed. Boat owners consistently report savings of around ten percent on fuel and speed gains of up to three knots.
The savings come from reduced drag across the entire running gear, not just the propeller. Boats that run regularly see the biggest benefit. For a full explanation of how the savings work and when to expect them, read our full guide: Does PropSpeed Actually Save Fuel?
Can PropSpeed Be Applied While the Boat Is in the Water?
No. The metal surfaces must be dry, stripped, sanded, and primed with precise timing between coats. A haul-out is required.
The most efficient approach is to schedule PropSpeed application alongside your regular bottom paint job so both get done in a single yard visit. Between applications, the coating needs only a gentle wipe during routine dive visits.
