- Locate and position four foundation spacers (P/N 11241) onto hull structure.
- For dissimilar metal foundations, locate and position four isolation gaskets (P/N 11145) (Fig. 13 & 14) onto foundation beams and apply a small bead of marine sealant (SILI-THANE 803 or equivalent) between both mating surfaces of each isolation gasket where it contacts the beam and the Seakeeper.
- Lower Seakeeper into position onto foundation beams and align over drilled holes.
- Install Mounting Bolts:
- For Blind-Hole installations (P/N 90400 – Seakeeper 6 Bolt-In Kit), install the Seakeeper supplied M12-1.75 fasteners to maintain a minimum thread engagement of 0.71 in. (18 mm). Apply a moderate coat of nickel-based anti-seize (e.g., SAF-T-EZE nickel grade anti-seize, SBT-4N or equivalent) to the threads of each bolt and include a small bead of marine grade sealant (e.g., SILI-THANE 803 or equivalent) under each bolt head and washer before installation. See Figure 15.
- For Through-Bolt installations (P/N 90660 – Seakeeper 6 Through-Bolt Kit), install the Seakeeper supplied M12-1.75 fasteners to maintain a minimum of 2 threads protruding past nut. Apply a moderate coat of nickel-based anti-seize (e.g., SAF-T-EZE nickel grade anti-seize, SBT-4N or equivalent) to the threads of each bolt and include a small bead of marine grade sealant (e.g., SILI-THANE 803 or equivalent) under each bolt head and washer before installation. See Figure 16.
- Torque all fasteners to 95 ft-lbs (129 N-m).
- New bolts, matching the Seakeeper specification, must be used for each installation and reinstallation that meet the requirements listed above.
- Proceed to electrical and cooling portion of the installation.
