Stern thruster installation has extra considerations and precautions and thruster installation procedures.
IMPORTANT
Avoid all casting where the motor-bracket is to be placed, as this will cause misfi t and possible failure to the gear house.
Tunnel installation
EN
With tunnel installed and cast.
1. Round the edges with a radius of 10% of the tunnel diameter.
2. For steel/ aluminium hulls make a slope with a length of 10-15% of the tunnel diameter.
(NB: If this is not possible, round the tunnel end as much as possible.)
3. Additionally cast two layers on the outside of the tunnel/ hull in a 10cm area
4. Follow the same method if making the de ector/ spoiler.
You must apply gel coat to areas you have grounded/ moulded to make waterproof. These areas allow water access
to the hull which is typically not waterproof without these applications outside. (NB: All original Side-Power tunnels are fully waterproof when
delivered except in the areas where you have cut and bonded it to the hull.)
