Description
The PRM90 mechanical gearbox is designed for recreational boats that need a reliable, durable and lightweight marine gearbox.
The gearbox's cone clutches, both front and rear, are mechanical and do not need to be adjusted. When driving forward, the output shaft rotates clockwise which requires a right hand propeller when driving forward.
The gearbox reduction ratio is 2.00:1 for both forward and reverse clutching.
The strong and lightweight aluminium gearbox housing is ribbed for strength and heat dissipation and therefore the gearbox does not require a separate oil cooler.
The output shaft can rotate freely with the gear in the free position. The marine gearbox is therefore also well suited for sailing boats, as there is no need to prevent the free rotation of the shaft (with the gearbox in the free position) when sailing.
Performance in recreational use is max. 50 hp and a maximum engine speed of 5000 rpm.
