Installation recommendations
To achieve the optimum performance, position the thrust tunnel as
far forward as possible.
In case of a planning vessel the
tunnel should, if possible, be so
situated that when the vessel is
planing it is above the water level
thus causing no resistance.
If a tunnel for a stern thruster is used then position this thrust tunnel
as close as possible near the stern of the boat.
3 .1 Positioning of the thruster tunnel
Several installation examples.
A stern thruster in a tunnel.
If, in addition to controlling the movement of the bow, the stern of
the vessel is required to move sideways, then a second ‘RimDrive’
may be installed at the stern.
When choosing the location for the thrust tunnel, take the following
into account for optimum performance:
- The distance A shown in the drawing must be at least 0.5 x D. (D is
the tunnel diameter).
- The shortest length of the tunnel (distance B) should be minimal
2 x D (500 mm, 20”).
Make the tube no longer than strictly necessary.
The ‘RimDrive’ can be installed in various positions from horizontal to
vertically upwards.
The connection box must always be positioned above the maximum
level of the bilge water.ester resin (Norpol Pl 2857).
The propeller should preferably be situated on the centre line of the
vessel, but it must always be accessible from the outside to replace
the anode if required.
In order to enable the installation the free space around the ‘RimDrive’
must be at least 10 cm (4”); size C.
