The new L70JM series features our latest advanced swept blade shape technology. A combination of blade shape, airfoil technology, and laminate structure work together to increase propeller performance. The JM series blade also mounts using our latest V series hub models. These hubs offer many features like easier pitch setting and accuracy, ability to assemble the entire unit off of the boat and finally an anti-theft deterrent option.

Sensenich’s “JM” Series propeller is designed to have the best characteristics of hunt style propeller along with reduced sound. This propeller system will produce a tremendous amount of low end push and will be available on all direct drive automotive and aircraft engines.

The 3 Blade 67-70" JM Series has quickly become a favorite of 240 - 300+ HP direct drive applications that are looking for the most available thrust.

All Sensenich composite ground adjustable blades are manufactured using an internal pressure, closed mold system. Aerospace grade epoxy preimpregnated carbon fiber and fiberglass a cured at an elevated temperature to give the optimum strength at the minimum weight. A co-cured stainless metal leading edge is bonded on flush with the airfoil. The stylish aluminum hubs are CNC manufactured from aerospace grade aluminum and offer easy pitch adjustment of the blades.
