Seakeeper 14 Installation Manual (90873-1)

2.4.4 Installation of Seakeeper

  1. 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.
    1. 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.
  2. Install Mounting Bolts, as shown in Figure 10 below:
    1. For Blind-Hole installations (P/N 90870 – Seakeeper 14 Blind-Hole Installation Kit), install the Seakeeper supplied Grade 10.9, M16-2.0 x 95 mm fasteners or alternative Grade 10.9, M16-2.0 bolts to maintain a minimum thread engagement of 0.94 in. (24 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.
    2. For Through-Bolt Installations (P/N 90871 – Seakeeper 14 Through-Bolt Installation Kit), install the Seakeeper supplied Grade 10.9, M16-2.0 x 120 mm fasteners or alternative Grade 10.9, M16-2.0 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.
  3. Torque all fasteners to 155 ft-lbs (210 N-m).
    1. New bolts, matching the Seakeeper specification, must be used for each installation and reinstallation that meet the requirements listed above.
  4. Proceed to electrical and cooling portion of the installation.
