Noise/Soundproofing/Ventilation Gyro noise has been measured under steady state conditions (no wave load) in Seakeeper's test facility. The steady state noise is typically in the range of 72‐74 dB unweighted. As the frequencies emitting the highest sound pressures are low (like other marine machinery), it is recommended that the gyro be installed in a cage in a ...

Product: Document #: Rev: Page: INSTALLATION MANUAL MODEL 26000 GYRO 90183 2 5 of 23 Section 1: MECHANICAL INSTALLATION 1.3 Selection of Installation Method The Model 26000 gyro can be affixed to the hull structure using two methods 1) Use saddle installation or 2) bolt‐ in installation. See figures below. Option 1 would be most commonly used on a hull constructed of glass reinforced plastic (GRP) or fiberglass. For this option, four 16 inch (406 mm) long by 8 inch( (203 mm) deep saddles are bonded to properly spaced and prepared structural members that are an integral part of the hull structure. Seakeeper recommends using a structural adhesive with a lap shear strength of 2000 psi (13.8 MPa) or greater. Careful consideration should be ...

exercised by the installer while selecting the appropriate adhesive. Compatibility with the gyro’s cast aluminum A356‐ T6 saddles, hull structure and pot life are three important factors to consider. Option 2 would be applied on a hull or gyro support structure constructed of steel or aluminum. The four isolation mounts would fasten directly to hull structure using 32x M16 or 5/8 inch fasteners. Depending on access around the boat’s structure blind threaded holes or thru‐bolting can be utilized. 1.4 Unpacking Crate 1) Reference Seakeeper Drawing No. 90155, Model 26000 Gyro Hardware Scope of Supply for items that ship with the gyro. 2) Reference Seakeeper Document No. 90203, Model 26000 Crate Unpacking Instructions for information on disassembling crate. 3) Remove angles used for installation fixtures – take care not to damage as any distortion of angles could result in foundation alignment problems. 4) Remove saddles (if applicable) electrical components, cables, and misc. items contained in boxes and set aside. 5) Remove 16 x lag bolts that fasten gyro to crate base. ...

/ installer to lay‐up and adjust the foundation dimensions to create a low‐clearance fit between the gyro foundation saddles and the hull structure. Shear strength of the adhesive will be maximized if the cured thickness between the vessel structure and gyro saddles is at the thinner end of the adhesive manufacturer’s recommended range. Therefore, the fixture should be used to confirm that the overall dimensions of the foundations are square and level and that the adhesive gap is within Seakeeper’s maximum recommended thickness of .13” or 3mm. Note: Do NOT use the installation fixture to establish gyro envelope dimensions. Refer to Drawing No. 90137 for envelope dimensions. A 3‐D model of the gyro is available on the Seakeeper website (www.seakeeper.com) ...

INSTRUCTIONS Product: All Document #: 90213 Process: Plexus PC‐ 120 Application Instructions Rev.: 1 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. ...

INSTRUCTIONS Page 2 of 4 Product: ALL Document #: 90213 Process: Plexus PC‐ 120 Application Instructions Rev.: 1 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 31
INSTRUCTIONS Page 3 of 4 Product: ALL Document #: 90213 Process: Plexus PC‐ 120 Application Instructions Rev.: 1 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. ...

INSTRUCTIONS Page 4 of 4 Product: ALL Document #: 90213 Process: Plexus PC‐ 120 Application Instructions Rev.: 1 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 ...
