Stern Thruster Mounting

When selecting the location to mount the stern thruster, the centre
line of the 'RimDrive' must be at least 250 mm below the waterline for
the best possible result.
Ensure sufficient free space around the 'RimDrive' within the boat, see
Overall Dimensions.
Also see Overall Dimensions for the dimensions of the hole in the hull.
The connection box must be mounted above the maximum bilge wa-
ter level.
Min. 250 mm
(10")
That section of the hull (stern)
where the 'RimDrive' is to be mount-
ed must be completely flat. If the
stern isn't flat, a shim can be used.
Min. 250 mm
(10")
If the stern height is insufficient for mounting the stern thruster, this
can be solved by placing an angled section. Do keep in mind that the
section for mounting the 'RimDrive' must be strong enough to cope
with the upthrust of the water under normal cruising conditions. It is
preferred to not have the 'RimDrive' protrude below the bilge.

Protection of the bow thruster against corrosion

To prevent corrosion problems, do not use copper based anti-fouling
on the RimDrive.
If copper based anti-fouling is applied to protect the hull make sure
that the RimDrive is fully sealed during application.

We do not recommend mounting
onto the bilge, as this will greatly
impede the forward movement of
the boat.
Due to the upthrust of the water
against the 'RimDrive' the stress on
the bilge of the boat, at the location
where the 'RimDrive' is mounted,
will be enormous.
Mount the 'RimDrive' with a perma-
nently flexible sealant, e.g. Sikaflex®-
291i
Remove the plastic set screws 'S' and
fit the stern thruster tunnels on to
the Rimdrive.

The centre line of the tunnel of a standard stern thruster installation
must be at least 1x the diameter of the tunnel below the waterline for
an optimum result.
The use of a extension kit for stern thrusters makes it possible for the
tunnel tube to be less than 1x the diameter of the tunnel below the
waterline.
The sucking in of air is prevented by this.
The upgrade kit is available as an option.

Cathodic protection is a 'must' for the protection of all metal parts
under water.
