The principle that enables the shaft mounted “SPURS” to cut so effectively is the “screw action” created as the propeller turns, winding lines, nets or weeds directly into “SPURS” blades, for an instant cut eliminating entanglement and damage to the running gear.
Our propeller mounted systems are meant for medium to large vessels. they instantly cut lines and nets before they become entangled. this prevents aft seal rupture, resulting oil pollution and other costly damage to your vessel. Spurs® manufactures cutter systems for fixed & variable pitch propeller and thruster systems.
Until now, spurs® has been well known for our line, net and weed cutters. due to popular demand, we have developed the spurs® spacers. the spacers are installed between the transmission and shaft flanges to extend the shaft. the spacers are cold-rolled steel and nickel plated, tolerance .001 for all dimensions, and one inch thick (standard). special orders can be made for thickness or size.
The PSS Shaft Seal is a mechanical seal that uses a self-aligning carbon-graphite stator to ensure a 100% watertight seal with proven reliability. This seal will eliminate shaft wear and minimize corrosion.
