TECHNICAL DESCRIPTION 
 

REVERSE GEAR 

The Volvo Penta reverse gear, type Mono Shift, has a reduction ratio of 1.9 1: 1. The 
reduction gear is integrally built with the reverse gear. The power transmission from 
the engine to the reverse gear is via a rubber flange. 
 
For operating "Forward" and "Reverse" the Volvo Penta patented cone clutch 'is 
used, which ensures smooth and quiet engagement. Very small forces are required to 
operate the reverse gear. 

 

Reverse Gear type Mono Shift (MSB).
