Description
PRM150 hydraulic Drop-Center marine gearbox for pleasure boats and light professional use via 2.82:1 reduction gearbox.
Power output
- For recreational use: 2.10 hp/100 rpm (1.57 kW/100 rpm) For example, at a maximum engine speed of 3200 rpm, the gearbox is suitable for an engine with a maximum power output of approximately 67 hp/ 50 kW.
- Maximum engine speed 4500 rpm (5000 rpm momentarily)
Gearbox design and operation
The gearbox's symmetrical drive shafting and friction caps both front and rear allow the gearbox to be used in forward driving with both right and left hand propellers. This makes the gearbox ideal for twin-engine installations.
The hydraulically operated gearbox uses engine oil instead of hydraulic oil and therefore responds quickly and smoothly to changes in direction. The aluminium shell of the gearbox is designed to be lightweight but robust. The gearbox is reliable and durable, but in the event of a hydraulic failure, the gearbox has a mechanical locking facility, allowing the gearbox to be driven to port in an emergency.
Weight (dry) 21 kg (does not include SAE adapter plate for engine mounting or drive plate).
Mounting to engine and output bracket
The SAE plate is selected according to the engine mounting and the drive plate according to the mounting plate/flywheel mounting on an engine-specific basis. The gearbox output flange size is 4".
