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 CV|
|For twin motor installation 2 x 115 H.P. (same rotational direction) =||230 CV|
|For twin motor installation 2 x 115 H.P. (in counter rotation) : 115 + 20% =||138 CV|
Now select in our range the hydraulic steering which complies with the maximum power of the motor(s) (see examples below):
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 motors equipped with long or extra-long shaft, contact us.
