Simple mechanical operation, lightweight, compact & rugged
The PRM90 gearbox is designed for use in pleasure craft where a simple lightweight transmission is required.
The cone clutches for both ahead and astern are mechanically operated and require no adjustment.
The gearbox is purpose built to operate with standard rotation engines i.e. providing a clockwise rotation of the gearbox input shaft when viewed on input. In forward drive the output shaft rotates opposite to input shaft therefore requiring a right hand propeller.
The reduction ratios offered are 2.04:1 and 2.50:1 with a common astern ratio of 2.5:1
The heavy duty aluminium gearcase is externally ribbed for strength and heat dissipation and therefore requires no oil cooler.
Direction actuation is by a lever with positive detent positions for ahead, neutral and astern. It is suitable for use with proprietary remote control operating systems which must be of the single lever dual action type, i.e. MORSE MT3 or SL3 which operates the engine throttle in conjunction with the gear lever.För större modeller eller mer information angående detta backslag - kontakta oss!
