PRM Gearbox
PRM Gearbox
HayNav offers marine gearboxes that are simple, lightweight, mechanically operated for usage in pleasure craft. As the cone clutches are mechanically operated, they require no adjustment. Neither does it require an oil cooler as they have heat dissipating heavy duty aluminum gearcases.
The marine gearboxes are purposely built to operate with standard rotation engines i.e. providing a clockwise rotation of the gearbox input shaft when viewed on input.
