27 BOW THRUSTER BT160Kgf
ENG
5.1 TROUBLE SHOOTING
Problem Solution
1) The electromotor runs, but there is no thrust
If the shearpin between the motor and driveshaft inside the boat is
broken
Replace shearpin and check the motor installation to ensure
correct connection of the shearpin before re-fitting the electromotor
Is the propeller in the tunnel fastened c orrect l y on the prop-shaft
(drivepin present)
Re-fasten or replace the propeller and/or drivepin.
With the motor removed, turn the driveshaft from inside the boat to
feel if the gears are engaging and turning the prop-shaft.
In case of a failure inside the gear house, we adv ice to get a
replacement gear house instead of attempting to repear the
internal gear and bearing system.
2) The thruster has an unexpected low performance.
Check the voltage at the thruster while you are trying to run it. - If less than 21Vdc at the thruster the voltage is to low for the
thruster to operate correctly.
- The battery is flat.
- The battery capacity is reduced because of very low
temperatures
- Bad electrical connection(s) due to e.g. corrosion.
Check that all the brush-springs sits correctly on the brushes in the
electromotor.
- If one or more brushes are loose/has no tens ion from the brush-
spring, the performance will be low.
Weed or fishing line has become caught in the propeller. - Clean all surfaces.
3) The electric motor does not start at all or runs only in one
direction.
Check that the voltage of the electromotor are correct for your
installation by t heir labels.
- If wrong, contact your dealer or distributor.
Check that the battery main switch is “ON”. - Switch on battery main switch.
Check if main fuse has burn out. - Check electrical cables, connections and then substitute the fuse.
Check the voltage at the thruster while you are trying to run it.
Keep main engine(s) running to have continuous charge to the
batteries.
- If less than 21V at the thruster the voltage is to low for the
thruster to operate correctly. In a 24V boat the thruster will operate
down to approx. 12V, but the performance will be very bad. Find
and correct the reason for this low voltage which will probably be
one or more of these points:
- main battery cable sizes and connections
- battery size and condition
- fuse and main power switch performance.
If the main solenoids on the thruster are not even trying to engage
(clicking) they are probably not getting a "run" signal from the
control system. Try to run the thruster without the panel by directly
connecting the red and the blue or the red and the white wires in
the control cable contact coming from the thruster
- If the thruster runs in both directions, try the same in the
connector that goes int o the back of the control panel. If it also
works in this position, check the contact and wires on the back of
the panel. If the panel does not turn on, measure the voltage
between the red (+) and the black (-) in the contact going into the
thruster. If the voltage is good, chances are that the panel is not
working.
If the thruster does not run at all, or only in one direction in the
above tests, check the internal wiring on the thruster motor,
solenoids to be in accordance with the wiring diagram.
- If wire connections are correct and the electric motor doesn’t run,
probably the solenoid is broken and needs replacing.
4) The bow thruster loses oil
Check if an oil leak is noticed inside the vess el. - First check the hose and its connections.
- Check the oil seal on the input shaft of the tail piece.
Check if no oil is seen inside the vessel. - Check the propeller shaft oil seal in the cover of the tail piece.
