This document is intended to give details and guidance to a boat builder or equipment installer to install the Seakeeper 26. The Seakeeper can produce loads up to 35.89 KN (8,070 lbs.) at each of the four mounts and careful consideration should be given to foundation design to ensure it can transfer these loads into the hull.
Page 4 2 of 21 Section 1: MECHANICAL INSTALLATION Precautions • The Seakeeper must only be lifted from the supplied lifting eyes (See Section 1.4). • The Seakeeper flywheel is supported by precision bearings. Make certain while unpacking and lifting the Seakeeper assembly to NOT drop or impart mechanical shock as damage to bearings could result.

Page 6 Seakeeper noise has been measured under steady state conditions (no wave load) in Seakeeper's lab. The steady state noise is typically in the range of 70-75 dB 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 7 5 of 21 Section 1: MECHANICAL INSTALLATION Selection of Installation Method The Seakeeper 26 can be affixed to the hull structure using two methods shown below: 1) Bolt-In Installation 2) Bond-In (Saddle) Installation OPTION 1 - DIRECT FASTENING OF SEAKEEPER FOUNDATION TO SHIPS STRUCTURE Option 1 would be applied when a metal structure is available for attachment.

4) Remove top and angled face cover panels to access lifting eyes. 5) Attach spreader bar to the two lifting eyes located on the top of the Seakeeper enclosure. Stay clear of any other parts on the Seakeeper. See Figure 3 below.
Page 9 Method. Important dimensional and load information is given in this drawing that will impact the design details of the structure that will receive the Seakeeper. It is assumed that a proper structural analysis has been performed for the hull structure to which the Seakeeper will be fastened to ensure proper strength margins for the loads the Seakeeper will create during operation.

Page 13 Refer to Seakeeper Drawing No. 90272, Seakeeper 26/20HD Saddle Installation Details. Important dimensional and load information is given in this drawing that will impact the design details of the structure that will receive the Seakeeper as well as selection of the adhesive to bond the Seakeeper into the hull.
Page 14 90265 12 of 21 Section 1: MECHANICAL INSTALLATION Note: Do NOT use the installation fixture to establish Seakeeper envelope dimensions. Refer to Drawing No. 90272 for envelope dimensions. A 3-D model of the Seakeeper is available on the Seakeeper website (www.seakeeper.com) to aid in designing the Seakeeper foundation and the space around the Seakeeper.

Page 17 Product: Document #: Rev: Page: INSTALLATION MANUAL SEAKEEPER 26 / 20HD 90265 15 of 21 Section 1: MECHANICAL INSTALLATION 1.6.2 Fiberglass Hull Preparation 1) Position installation fixture (Fig 9) on hull girders noting recommended clearances for maintenance from Figure 2. Check that the screws fastening the saddles to the installation fixture are tight (Fig 6).
Page 18 8) Re-position installation fixture on girders and double-check that the adhesive gap is within the adhesive manufacturer’s maximum recommended thickness. (Note gap will be larger due to absence of gel-coat.) Seakeeper recommends a maximum gap of 3 mm if using Plexus MA590.

Page 20 .080” (2 mm) on top surface of hull as shown in Figure 13. 3) Thoroughly clean with alcohol or acetone the inside surfaces of Seakeeper foundation saddles to remove any contaminates as shown in Figure 13. Use new paper towels for cleaning, not shop rags.
Page 21 Section 1: MECHANICAL INSTALLATION 1.6.4 Bonding Saddles to Hull Note: If using Plexus MA590 adhesive, the Seakeeper saddles should be installed when PC- 120 is confirmed dry. 1) Assemble Plexus cartridge into either the manual or pneumatic gun as shown. Remove cap on cartridge and attach mixing tip.

Page 23 Allow adhesive to cure per manufacturer’s recommendations. Follow adhesive guidelines for curing time versus temperature. 12) Bonding of Seakeeper saddles onto the hull is now complete. Remove installation fixture. 1.6.5 Installation of Seakeeper 1) Rig the Seakeeper for lifting and lower it into position onto top surface of four saddles.
Page 24 INSTRUCTIONS Product: All Document #: 90213 Process: Plexus PC‐ 120 Application Instructions Rev.: 2 Process Description: Instructions for use of surface conditioner Page 1 of 4 What is Plexus PC‐120?  Plexus PC‐120 is a dual function primer/conditioner designed to clean surface contamination and leave a thin coating of primer on specific metal surfaces.  Although designed specifically for cleaning and priming of Aluminum and Stainless Steel, PC‐120 can be used to clean other surfaces in special situations. Contact Plexus Technical Service for recommendations on any surface other than Aluminum or Stainless Steel. Plexus PC‐120 works by:  Cleaning the surface of contamination using Isopropyl Alcohol to “lift” machine oils and other contamination.  Depositing a thin Phosphate based coating to retard corrosion.  Leaving a light “pink” color to assist in determining what areas have, and have not, been treated with PC‐120. How should PC‐120 be used?  PC‐120 can be brushed, wiped or sprayed onto the surface being primed. ...
Page 25 INSTRUCTIONS Page 2 of 4 Product: ALL Document #: 90213 Process: Plexus PC‐ 120 Application Instructions Rev.: 2 1) Using too much PC‐120  Only a very thin coat should be left on the metal. You should be able to see a slight “pink” cast as illustrated below. Too Much PC‐120 Correct Amount 2) Not removing oils once primed Wipe the surface with a dry rag  The solvents in PC‐120 will clean and “lift” most machining oils, but if the metal isn’t wiped clean of these oils then they will be deposited right back onto the metal surface when the solvent in PC‐120 evaporates! ...
Page 26 INSTRUCTIONS Page 3 of 4 Product: ALL Document #: 90213 Process: Plexus PC‐ 120 Application Instructions Rev.: 2 3) Not abrading corroded surfaces  As good as PC‐120 is, it can’t help bonding performance if applied to a surface that is already corroded!  Any surface that shows signs of corrosion should be cleaned by sanding or wire brushing to remove any scale or corrosion.  After removal of corrosion then treat the surface with PC‐120 as you normally would. 4) Using PC‐120 past it’s shelf life  When stored under normal conditions PC‐120 has a shelf life of 12 months in an unopened, original container.  PC‐120 bottles are marked with a lot number that is a simple 8 digit code that gives you the date of manufacture. o “807241” for example is 2008, 07 month (July), 24th day (the “1” refers to the first batch of PC‐120 made that day). Use the lot number to make sure the material is still within shelf life.  Since it contains isopropyl alcohol, PC‐120 should be tightly capped when not in use to stop evaporation. ...
Page 27 INSTRUCTIONS Page 4 of 4 Product: ALL Document #: 90213 Process: Plexus PC‐ 120 Application Instructions Rev.: 2 Remember these points! To avoid problems with Plexus PC‐120:  Don’t use too much PC‐120. Only a thin layer is needed.  Use a clean rag to wipe PC‐120 off before it completely dries to remove surface contaminants it has cleaned. Good quality paper towels are a better choice to minimize introduction of contaminates to surface.  Any sign of corrosion already on the surface should be removed by abrading BEFORE priming.  Check the lot number for the date to make sure the PC‐120 is less than a year old. Questions  Please contact Plexus Technical Service at 1‐800‐851‐6692 or info@itwplexus.com ...

• Installer is responsible for supplying a dedicated seawater pump and associated plumbing. Seawater connections on the Seakeeper heat exchanger mate with ¾ inch (19 mm) hose. • There is no need to disconnect hose from glycol pump except to replace the pump. In this case, provision will need to be made to catch draining glycol as plumbing is disconnected.

Page 44 Refer to Figure 1. In addition to initial operation at dock, new Seakeeper installations should be checked for minimum 4 GPM (16 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.

The Installation and Start-Up Checklists in this section provide an overview of the primary steps covered in the installation manual and should be referenced throughout the installation process. Upon completing the installation, the installer should commission each Seakeeper unit with the Seakeeper Commissioning Form (90437). The Commissioning Checklist (SWI-105) provides a checklist of items to inspect and verify during the commissioning process and serves as a supplement to the Commissioning Form.
