1)
GENERAL INSTALLATION GUIDLINES
Decide on the best location for the SUPER POWER (See drawing: “Positioning & Measurements” at
back of manual).
The tunnel must be as low as possible and as far forward as possible.
The propellers must not protrude beyond the hull line.
The ideal position of the tunnel is such that there is at least the depth of one tunnel diameter from
the water line to the top of the fitted tunnel.
Decreased performance of the SUPER POWER due to inadequate immersion depth can be
compensated by fitting the tunnel as far forward as possible (increasing lever arm movement).
The SUPER POWER hydraulic thrusters can be fitted vertically, horizontally or tilting.
IMPORTANT: When using tunnels of different thickness (example: metallic tunnel) it is imperative
that the area between the drive leg/gasket and the motor support, matches the
thickness as indicated in the table on the drawing “Positioning & Measurements” at
back of manual and that the motor support is stable.
If you have less than 8 mm thickness, you will require an extra hard rubber gasket
between the motor support and the tunnel.
2)
TUNNEL
When the final tunnel position is determined (and all dimensions have been checked), mark the
centre of the tunnel’s position and drill a Ø 10 mm hole. Make up a metal compass from 8 mm rod.
Fit compass into the Ø 10 mm holes and trace the form of the tunnel on to the hull (elliptical).
After cutting out the elliptic hole, disc the interior surface of the hull, by approx. 10 to 15 cm
around the holes.
The outside surface of the tunnel is then ready to be fibre-glassed.
Do not
stratify over
this zone
Fit the tunnel and mark the areas to be fibre-glassed. Sand these areas inside and out.
In certain installations it is preferable to drill the position of the thruster support before the
installation of the tunnel.
Refit the tunnel. Apply reinforced fibreglass filler to all areas, taking care that you fill the gap
between hull and tunnel. Stratify with a minimum of 8 coats of material and ISOPHTALIQUE
RESINE alternating with mat and roving.
In inaccessible areas (i.e. under the tunnel), it is possible to simply apply reinforced filler.
