A shaft driven cutter that will instantly cut any rope, weed or debris picked up by the propellor. Made from 316 stainless steel, & with no moving parts, the razor sharp blade is quick & easy to install. The slide-on version simply slides onto the shaft after the propeller has been removed and is secured with a set screw that locates into a small drill dimple made in the shaft. Manufactured in one piece with a width of only 12mm (0.47'), it is designed for installations where the gap between the propeller and the shaft bearing is small. A gap of 18mm (0.7') is sufficient; this includes 6mm (1/4') of space for water to circulate to the shaft bearing.
