Positioning the stern thruster
For best performance, the thruster must be installed as deep on the stern as possible and the thrusters water flow must not obstruct any objects.
The thruster should be installed as deep under the waterline as possible for two reasons:
1. So it does not suck air from the surface which will reduce performance and increase noise levels.
2. To receive maximum effi ciency and thrust.
The thruster must be installed to ensure the propulsion water flow must not be obstructed by other objects. Objects that obstruct the water flow will
greatly reduce the thrust output.
Position
The thruster can be installed in multiple locations on the boat transom. Installing the thruster slightly off centre will not affect the overall effectiveness
of the thruster. Installing the thruster off centre may be required to avoid any obstructions externally or internally on the vessel.
Ensure that the external stern thruster assembly does not disturb the water flow under the hull. At higher speeds, if the thruster is installed to low can
cause damage to the thruster, additional drag and unwanted water splashing.
Alignment
The thruster can be installed at a slight angle if required for the water flow to avoid obstructions. These obstructions can include propellers systems,
trim tabs or the hull. The average force the thruster propels water is 5-7 meters per sec, therefore angled installations must be as deep as possible
under the water to minimise spray breaking beyond the water surface.
(NB: install the thruster at an angle only if no other suitable location can be
found.)
