2.3 Bolt-In Installation

2.3.1 Preparation of Boat Structure

The Seakeeper Drawing No. 90590, Seakeeper 2 Generic Installation Guide shows various structural arrangements to support the installation of the Seakeeper. The Generic Installation Guide offers above and below deck installation arrangements with fiber-reinforced plastic (FRP) and aluminum structures, which should provide solutions for most vessels. The Seakeeper 2 is affixed to the hull structure via four bolts in the
Seakeeper 2 frame. Depending on the structure to which the Seakeeper is fastened, blind threaded holes or through-bolting can be utilized.

Refer to Seakeeper Drawing No. 90487, Seakeeper 2 Bolt in 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. 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.

The hull structure supporting the Seakeeper should be installed so the Seakeeper is parallel to the waterline in the transverse direction and within 1 degree longitudinally.

In addition, the four areas on top of the structure on which the Seakeeper 2 frame and isolation gaskets will rest, need to be co-planar within .06 in. (1.5 mm) to minimize potential distortion of Seakeeper support frame when installed. The isolation gaskets are only used when the Seakeeper 2 is mounted to a dissimilar metal structure.

Seakeeper offers an optional installation template kit, P/N 90473, which contains four plates that mimic the mating surfaces of the four feet located on the Seakeeper ’s foundation. These plates have 4 holes located at the same centers as the mounting holes on the Seakeeper 3.The fixture locates the hole patterns at the proper spacing both in the forward-aft direction and the port-starboard direction. See Figure 4 below. Once assembled, the fixture can be used to check clearances and alignment of the hull structure.

Note: Do NOT use the installation fixture to establish the Seakeeper envelope dimensions. Refer to Drawing No. 90487 – Seakeeper 2 Bolt-In Installation Details, for envelope dimensions. A 3-D model of the Seakeeper is available on the Seakeeper Dealer Access website (www.seakeeper.com) to aid in designing the Seakeeper foundation and the space around the Seakeeper

NOTE: MAKE SURE NO OBSTRUCTIONS FROM THE HULL STRUCTURE CAN BE SEEN WITHINTHE INSIDE OF THE INSTALLATION TEMPLATE KIT (INSIDE THE MARKED RED LINES) AS SEEN IN FIGURE 5. REFERENCE SEAKEEPER DRAWING NO. 90487 – SEAKEEPER 2 BOLT-ININSTALLATION DETAILS

CAUTION: Tight clearances from cable guide bands to hull structure. See above Figure 5 for dimensions and reference Seakeeper Drawing No. 90487 – Seakeeper 2 Bolt-In Installation Details, for complete Seakeeper 2 envelope.

2.3.2 Transfer of Holes to Boat Structure

1. Lower assembled fixture onto hull structure.
2. The four areas where the feet of the Seakeeper will rest should be coplanar to within .06 in. (1.5 mm). See Figure 6.
3. Align fixture in desired location and transfer holes from fixture plate to the hull structure using provided transfer punch. Note that holes in fixture plate are ø0.60 in. (15.138 mm).
4. Remove fixture and drill and tap M14X2.0 Helicoil threaded insert holes in hull structure at marked locations to mate with holes in the Seakeeper foundation. Take special care to drill perpendicular to mounting surface. A drill guide is recommended. Remove any impeding obstructions.

2.3.3 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 4 isolation gaskets onto foundation beams and apply a small bead of marine sealant (e.g., SILI-THANE 803or equivalent) between both mating surfaces of each isolation gasket where it contacts the beam and the Seakeeper (See Figure 7).

2. Install mounting bolts:
   
   1. For Blind Hole Installations, install the Seakeeper supplied Grade 10.9, M14-2.0 x90 mm fasteners or alternative Grade 10.9, M14-2.0 bolts to maintain a minimum thread engagement of 0.83 in (21 mm). If Seakeeper supplied bolts do not achieve the minimum thread engagement because of the lamination thickness or structure, longer bolts of the same specification (M14-2.0, Grade10.9) should be sourced. If tapping directly into a metal frame shorter bolts maybe required. Apply a moderate coat of marine 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 8 below.
   2. For Through-Bolt installation install the Seakeeper optional Thru-Bolt Kit (P/N 90636) Grade 10.9, M14-2.0 x 100 mm fasteners with a minimum of 2 threads passing through the nut If Seakeeper supplied bolts do not pass entirely through the Extra Wide / Heavy Hex Nut because of the frame thickness, longer bolts of the same specification (M14-2.0, Grade 10.9) should be sourced. Apply a moderate coat of marine anti-seize (e.g., SAF-T-EZE nickel grade anti-seize, SBT-4Nor 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 9 below.

4.1 Cooling Installation Introduction

Reference Documents & Drawings

• 90469 – Seakeeper 2 Hardware Scope of Supply
• 90490 – Seakeeper 2 Cooling Water Schematic
• 90470 – Seakeeper 2 Cable Block Diagram

• TB–90191 – Seawater Cooling Pump Recommendations
• 30331 – Seakeeper DC Seawater Pump Assembly

The Seakeeper 2 is shipped with the cooling circuit filled and ready for use. The Seakeeper 2 requires connection to a raw water pump, referred to as the seawater pump, to cool the closed loop cooling circuit on the unit.  The required seawater flow through the Seakeeper 2 heat exchanger is between 2 – 6 GPM (7.6 – 22.7 LPM), under all vessel operating conditions. Prior to operation, confirmation of glycol level is required.

Seakeeper offers a compatible self-priming DC Seawater Pump (P/N 30331) that is prewired for the Seakeeper 2 Installation and covered under the standard Seakeeper warranty. See Drawing No. 30331, SeaFlo Seawater Pump Assembly for details and the Seakeeper Options and Accessories Price List for pricing information.

4.2 Installation Considerations

1. The installer is responsible for supplying a dedicated seawater pump and associated plumbing. An optional seawater pump can be purchased through Seakeeper, P/N 30331.
2. Seawater connections on the Seakeeper heat exchanger mate with ¾ in. (19 mm) hose.
3. The seawater pump is powered via the “SW Pump 12 VDC Out” connection on the Seakeeper 2 wire harness, as outlined in Electrical Installation Section.
4. The seawater pump operates on 12 VDC with a max overcurrent protection rating of 15 A.
5. A dedicated through-hull fitting should be installed for each Seakeeper unit onboard the vessel to ensure sufficient seawater flow to each unit.
6. It is recommended that the seawater pump is located below the waterline, as close to the baseline of the vessel as practically possible, to maintain positive inlet pressure on the pump in all operating conditions.
7. A self-priming seawater pump may be required to maintain water flow in all underway conditions. Cavitation can occur at the seawater inlet and potentially cause an air-lock condition restricting seawater flow to the heat exchanger.
8. Maximum allowed seawater pressure in heat exchanger is 20 psi (1.4 bar)
9. Seawater flow requirement through heat exchanger is 2 GPM (7.6 LPM) minimum and 6 GPM (22.7 LPM) maximum under all operating conditions of the boat. When sizing seawater pump, installer should factor in losses for raw water plumbing. In addition to initial operation at dock, new Seakeeper installations should be checked to be within the flow requirements while vessel is at speed. Flows higher than 6 GPM (22.7 LPM) could affect heat exchanger life.

4.3 Connecting Seawater to Heat Exchanger

Refer to Figure 25 for typical seawater plumbing arrangement.

1. Connect seawater pump to Seakeeper dedicated through-hull fitting. A strainer and seacock valve should generally be installed between the seawater inlet and the pump.
2. Connect seawater from installer supplied pump to lower 3/4 in. (19 mm) hose barb on heat exchanger. Use the same practices as other below waterline seawater plumbing.
3. Connect seawater discharge to overboard drain. Use the same practices as other below waterline seawater plumbing.
4. Required flow rate is 2 GPM (7.6 LPM) minimum and 6 GPM (22.7 LPM) maximum.
5. 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.
   
   1. If no other method of confirming flow is available, discharge line may be temporarily diverted to a bucket. Flow is calculated from time to fill a known volume.
   2. Flowrates in excess of 6 GPM (22.7 LPM) could affect heat exchanger life.
6. Inspect raw water plumbing after sea trial for any signs of leakage.

4.4 Seakeeper Optional DC Seawater Pump

1. Seakeeper offers a self-priming DC Seawater pump as an optional addition, P/N 30331 – DC Seawater Pump Assembly, shown in Figure 26.
2. The Seakeeper Seawater Pump is a 24 VDC pump operated at 12 VDC for the Seakeeper 2 and maintains a seawater flow of approximately 2.5 GPM (9.5 LPM) at 12 VDC.
3. The pump assembly is pre-wired for connection to Seakeeper 2 Cable 5 and includes a seawater strainer and various fittings. The pump specifications are as follows:

NOTE: Use only SeaFlo-provided threaded fittings for DC Seawater Pump 30331.

4.5 Adding Coolant

1. The Seakeeper 2 cooling system is filled to proper level when shipped. If level has dropped, check for evidence of leaks at all connections before adding fluid as described below. If coolant is at the correct level, skip to Step 5.
2. The minimum and maximum glycol fill levels are shown in Figure 27.

3. Mix 50% ethylene glycol with 50% distilled water in a clean container. Refer to Table 1 or glycol manufacturer’s literature for freezing points.
   
   1. It is required that ethylene glycol with corrosion inhibitors be used. Most commercially available glycol has these additives standard.

4. Remove reservoir cap and pour mixture in until level reaches top face of the reservoir enclosure, as shown in Figure 27.
   
   1. Filling reservoir above this level will not cause any damage but coolant may be expelled from the vented cap due to normal thermal expansion of coolant.
5. Once the Seakeeper 2 and DC seawater pump are connected to 12 VDC power:
   
   1. Check the Seakeeper Display interface for any ALARMS.
   2. Cycle the Seakeeper 2 power, and press the POWER ON button.
   3. The flywheel will start to spin, and the glycol pump will start.
   4. Recheck glycol level with fluid circulating in coolant circuit to ensure the correct fill level is maintained.
6. After several minutes of running, press POWER OFF button.
7. The cooling system is self-purging. If small amounts of air are in the system, they should be dislodged during the first sea trial. Recheck level after sea trial and add fluid if required.
   
   NOTE: It is not uncommon to see some air in the coolant system. It is normal and will not affect operation.
