Close coupled V-drive
The engine and reverse gear form one unit. The axial
forces from the propeller are absorbed by an axial
bearing in the reverse gear.
Design concepts of propulsion systems
There are different types of engines, reverse gears and drive systems, depending on the available space and oth-
er requirements during the installation.
Follow the manufacturer’s instructions when installing components and equipment not supplied by Volvo Penta.
Reverse gear, various types
Drop centre, parallel
The engine’s crankshaft and the reverse gear’s output
shaft are parallel. The output shaft is on a lower level
than the crankshaft.
The engine and reverse gear form one unit. The com-
pressive forces from the propeller are absorbed by an
axial bearing in the reverse gear.
Drop centre, down angle
The engine’s crankshaft and the reverse gear’s output
shaft are on different levels. The angle of the propeller
shaft deviates from the angle of the crankshaft.
The engine and reverse gear form one unit. The com-
pressive forces from the propeller are absorbed by an
axial bearing in the reverse gear.
