Installation Guide

Before beginning the installation, ensure you have the necessary marine tools and safety equipment. The work should be done in a clean, well-lit, and ventilated area. Verify the vessel is secure and the sail drive system is completely drained.

1. Preparation: Disconnect the sail drive unit from the engine and ensure all hydraulic pressure is released.
2. Removal: Carefully remove the old rubber bellow, noting the orientation and placement of the sealing surfaces.
3. Cleaning: Thoroughly clean all mating surfaces on the hull and sail drive. Inspect for any damage, corrosion, or wear.
4. Installation: Position the new rubber bellow, ensuring it is correctly aligned with all sealing surfaces.
5. Securing: Apply the appropriate marine-grade sealant as specified by the manufacturer and secure the bellow and drive unit.
6. Testing: Once the sealant has cured, perform pressure testing to verify a proper, watertight seal has been achieved before launching the vessel.

Note: We strongly recommend professional installation by a certified marine technician. Proper installation is critical for the safety and integrity of your vessel.
