Page 3 This document is intended to give details and guidance to a boat builder or equipment installer to install the Seakeeper 3. The Seakeeper 3 is capable of producing loads up to 8.60KN (1,934 lbs.) at each of the four mounts and careful consideration should be given to foundation design to insure it is capable of transferring these loads into the hull.
Page 4 While handling / installing the Seakeeper assembly, do not allow electrical fittings that exit bottom of the Seakeeper enclosure to come in contact with any surface or object as this could damage the fittings and potentially affect the vacuum integrity of the enclosure.

Page 6 90378 4 of 15 Section 1: MECHANICAL INSTALLATION FIGURE 3 – BEAMS CLEARANCE CONSIDERATIONS Refer to Figure 3 for recommended clearances to transverse or longitudinal beams. Clearances aft of the Seakeeper are shown to provide access for regular scheduled maintenance.
Page 7 Seakeeper noise has been measured under steady state conditions (no wave load) in Seakeeper's lab and in our test boat. The steady state noise is typically in the range of 64-66 dBC un-weighted. As the frequencies emitting the highest sound pressures are low (like other marine machinery), it is recommended that the Seakeeper be installed in a machinery space that is already treated with soundproofing.
Page 8 2) Remove covers, electrical components, display, cables, and misc. items and set aside. 3) Remove packing materials that secure Seakeeper assembly inside the crate. 4) Attach a spreader bar (Seakeeper #80283) to the two lifting eyes located on the top of the Seakeeper enclosure.
Page 9 Longitudinal Bolt-In Installation 1.4.1 Check and Preparation of Hull Structure The Seakeeper 3 can be affixed to the hull structure using two methods 1) Longitudinal Beam Bolt-In installation or 2) Transverse Beam Bolt-In installation. Neither option affects the operation of the Seakeeper. However, one option might ease the installation process or allow for a larger service envelope.
Page 10 8 of 15 Section 1: MECHANICAL INSTALLATION FIGURE 5 – EXPLODED VIEW OF INSTALLATION FIXTURE CAUTION: Tight clearances from cable guide bands to hull structure. See above figure for dimensions and reference Seakeeper drawing NO. 90374 for complete Seakeeper 3 envelope.
Page 11 1.4.2 Transfer of Holes to Boat Structure 1) Lower assembled fixture onto hull structure. The four areas where the feet of the Seakeeper will rest should be coplanar to within .06” (1.5 mm). See Figure 10. 3) Align fixture in desired location and transfer holes from fixture plate to the hull structure.
Page 12 Apply a small bead (approximately 4 mm wide) of sealant (silicone or caulk) between both mating surfaces of each isolation gasket where it contacts the beam and the Seakeeper. This will prevent water from wicking between the parts and setting up corrosion. Check isolation gasket alignment by test fitting bolts without any obstructions.

Neither option affects the operation of the Seakeeper. However, one option might ease the installation process or allow for a larger service envelope.

This will prevent water from wicking between the parts and setting up corrosion. Check isolation gasket alignment by test fitting bolts without any obstructions.
Page 17 5) Remove the Seakeeper unit using a spreader bar. 1.6.2 Disposal DO NOT disassemble the Seakeeper to a greater degree than necessary for removal from the boat. DO NOT dispose of a Seakeeper unit in a landfill. The unit must be shipped back to Seakeeper.

Refer to Table 1 or glycol manufacturer’s literature for freezing points. It is required that ethylene glycol with corrosion inhibitors be used.
Page 34 Connect seawater discharge (upper hose barb) to overboard drain. Use the same practices as other below waterline seawater plumbing. In addition to initial operation at dock, new Seakeeper installations should be checked for minimum 2 GPM (7.6 LPM) flow while vessel is at speed and when backing down. If no other method of confirming flow is available, discharge line may be temporarily diverted to a bucket.
Page 35 2) Supply 12 VDC 100A to Motor Drive Box at customer supplied electrical disconnect. 3) If seawater pump for the Seakeeper is not supplied though cable from Motor Drive Box, turn on the boat’s DC dedicated circuit breaker that supplies power to the seawater pump.
