Seakeeper 9 Installation Manual (90222-10); S/N 9-212-3388 to 9-234-4899
2.4.5 Installation of Seakeeper
- Lower Seakeeper into position onto the hull foundation beams and align over drilled holes. Apply a small bead of marine sealant (e.g., SILI-THANE 803 or equivalent) between mating surfaces of Seakeeper frame and hull structure to prevent moisture wicking into bolt holes.
- For dissimilar metal foundations, locate and position the 4 isolation gaskets (P/N 10860) onto foundation beams and apply a small bead of marine sealant (e.g., SILI-THANE 803 or equivalent) between both mating surfaces of each isolation gasket where it contacts the beam and Seakeeper.
- Install Mounting Bolts, as shown in Figure:
- For Blind-Hole installations (P/N 90642 – Seakeeper 9 Bolt-In Installation Kit), install the Seakeeper supplied Grade 10.9, M14-2.0 x 85 mm fasteners or alternative Grade 10.9, M14-2.0 bolts to maintain a minimum thread engagement of 0.90 in. (23 mm). Apply a moderate coat of nickel-based anti-seize (e.g., SAF-T-EZE nickel-based 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.
- For Through-Bolt Installations (P/N 90643 – Seakeeper 9 Through-Bolt Installation Kit), install the Seakeeper supplied Grade 10.9, M14-2.0 x 100 mm fasteners or alternative Grade 10.9, M14-2.0 bolts 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-based 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.
- Torque all fasteners to 100 ft-lbs (136 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.
