1. Mark the tunnel centreline and the boat’s centreline.
(NB: Install the gear leg and propeller as shown above for the thrust direction to
correspond with the control panel. Position gear leg with the P-mark facing port and the S-mark facing starboard.)
2. Use the gasket or template (recommended) to mark the hole centres and double-check the measurements. The centre hole MUST be placed using
the boat centreline as shown above.
(NB: All holes must be in-line with the tunnels’ centreline for correct installation, clearance between
the propeller and the tunnel is minimal.)
3. Smooth the surface of the tunnel. A rough surface will cause possible failure/movement of the gear leg. The motor bracket must rest steadily on the
tunnel.
4. Drill the main centre hole followed by the two screw-holes.
5. Place the gear leg (without the propeller) with the gasket on inside the tunnel. Place the propeller on the gear leg to ensure it is centred and rotates
freely with the same clearance from each blade to the tunnel wall. Place top motor bracket to measure the drive shaft has come through the motor
bracket at the correct height. Remove the gear leg and propeller for fi nal installation.
6. Apply appropriate sealant to both sides of the gasket and place on the gear leg. Place the gear leg in the tunnel (without the propeller).
7. Install the top motor bracket and gear leg gently together. Use appropriate sealant to ensure that no leakages occur.
(NB: See your sealant data
sheet for the correct application process.)
8. Fasten the gear leg and the motor bracket with the bolts provided. Fasten to torque as shown above.

1. Centre the drive pin and Insert the propeller onto the shaft spine. Rotate the propeller until the drive pin aligns with the internal slot in the propeller.
2. Insert the washer to the end of the shaft spline. Tighten with the propeller lock-nut.
3. Insert the anode to the end of the propeller and tighten the anode holding screw. Apply a thread glue (Loctite 243 or similar) to ensure that the
anode holding screw does not unscrew itself from during the rotation of the propeller.
4. Apply anti-fouling to the gear leg and propeller. Do not apply anti-fouling to any rubber elements of the gear leg or anodes.
IMPORTANT
For twin counter-rotating gear legs, propellers are marked with P (Port) and S (starboard) and must be installed appropriately.
