To select a steering system in our range, first determine the maximum horse power developed by the outboard motor(s) and the rotational direction of the propellers on installations with several motors.
- Selection of Steering System for twin motor installations working in the same rotational direction: add the power of both motors (see example below).
- Selection of Steering System for twin motor installations working in counter-rotation: take into account the power of one motor only + 20% (see example below).
| Mounting exemples | Maximum power |
| For the installation of one single motor 1 x 115 H.P = | 115 HP |
| For twin motor installation 2 x 115 H.P. (same rotational direction) = | 230 HP |
| For twin motor installation 2 x 115 H.P. (in counter rotation) : 115 + 20% = | 138 HP |
For twin motor installations when the calculated maximum power exceeds the maximum power the steering system is given for (ex.: 2 x 200 H.P. in same rotational direction = 400 H.P.), it will be necessary to install a cylinder on each motor with a parallel hydraulic circuit (see Types of assemblies).
Note: For 4-blade propellers or more and for motor equipped with twin propellers or with long or extra-long shafts, please contact us.
