2.3.3 Installation of Seakeeper

  1. For dissimilar metal foundations, locate and position four isolation gaskets (P/N 14306) (Fig. 15) 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.
  2. Lower Seakeeper into position onto foundation beams and align over drilled holes.
  3. Install Mounting Bolts:
    1. For Blind-Hole installations (P/N 90911 – Seakeeper 7.5 Blind-Hole Installation Kit), install the Seakeeper supplied M16-2.0 fasteners to maintain a minimum thread engagement of 0.95 in. (24 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 14.
    2. For Through-Bolt installations (P/N 90912 – Seakeeper 7.5 Through-Bolt Installation Kit), install the Seakeeper supplied M16-2.0 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 15.
  4. Proceed to electrical and cooling portion of the installation.
