- Drill the remaining positions and fasten the other screws.
- Tighten screws and nuts in a cross pattern to the torques above, then repeat on the other side. Check the fixings periodically.
- The cowls are designed only for Quick stern tunnels. Do not use them as a step or support to get on and off the boat.
- Work in good light with suitable PPE; fitting and later inspections or repairs by qualified personnel only.
