Gear Leg & Motor Bracket Installation
!
Please refer to the graphic for special considerations relating to your model
!
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.
