Step by step - Thruster installation
The thruster must be mounted in the direction shown on
Fig. 1/1b
, both if mounted in bow and stern (the hatch must
open torwards the direction of travel).
If the unit is to be used as a bow thruster, find the position furthest forward where the unit will fit - allowing for 10cm
space around all sides of the unit for moulding, but not so far forward that the propeller will not go deep enough in the
water. Mounting the unit further forward will give less depth for the propeller, but better leverage effect for turning the
boat in crosswinds. Used as a stern thruster, the unit should be placed as far aft as possible.
Check the space requirements inside for the height, and propeller depth under the waterline.
Find the most forward position where thruster unit will fit, so center of the deployed thruster tunnel is at minimum
250mm
under the waterline.
Place unit where intended, take necessary measurements to check that the complete unit with motor, relay
cover and actuator(s) fit in the designated space for installation and service access. It is highly recccomend
-
ed that the area is dry at all times, and the thruster do NOT get exposed to water.
1. When correct position of thruster is decided, use the
SRF flange to mark inside hatch cutting lines as thruster
positioning refrence. Mark centerlines on SRF flange
and hull.

IMPORTANT!
If hull is made of sandwich materials, ensure to remove
sandwich materials and prepare moulding area for GRP
moulding process. This is the installer/boatbuilder full
responsibility.
