Optional ‘Soft Shift’ for PRM Transmission

Suitable for PRM 260, 280 & 500 Models

PRM transmission are renouned for their quality and reliability, however in some applications and/or circumstances they can be slighlty abrupt and noisey when gear changes are made and a transmission ‘jolt’ maybe experienced. The Beta Marine ‘Soft Shift’ option slows down the gear engagement time which provides a smooth and silent transition between forward, neutral and reverse. Soft Shift for PRM Guidelines PDF.
