I have a brand new 2025 saver 45 SE with a sea keeper 6 which is leaking, which I believe is hydraulic fluid. It leaks a little more and rougher conditions than calm. Should I have the saber dealer check it out?

Page 3 Seakeeper’s web site at www.seakeeper.com. The Seakeeper web site also contains videos of Seakeeper operation and videos of several different boats operating in waves with the Seakeeper on and off. It is recommended that the reader play these videos prior to reading the remainder of this manual.
Page 4 (termed precession rate) play an important role in its operation. These parameters are illustrated in Figure 2. At zero degree gimbal angle, the Seakeeper is vertical; it can precess a maximum of +/- 60 degrees about this position. The amount of torque that the Seakeeper exerts on a boat’s hull to counter the wave induced roll is directly proportional to the precession...
Page 5 There is a large torque about the gimbal axis when the Seakeeper is precessing. Seakeeper cover panels are provided to prevent personnel or equipment from contacting the Seakeeper while it is in operation. These covers should not be stood on, or have anything placed on top.
Page 6 This foundation transfers the loads that the Seakeeper produces to the hull structure. An active hydraulic brake mechanism is located on the Seakeeper assembly to regulate the Seakeeper’s precession motions about the gimbal shaft. It includes two hydraulic cylinders and a hydraulic manifold.
Page 7 1.2 Display The display shown below is the user interface to the Seakeeper 6 and should be mounted at the primary helm station. It is used to start, operate, monitor and shutdown the Seakeeper. Sensors, alarms and shutdowns are provided to allow unattended operation.
Page 8 Electronic Control Module (ECM). The glycol/water mix that cools the Seakeeper is also circulated through a cold plate inside the Drive Box to remove heat from high- power electronic components.
Page 9 Locking solenoids are installed in the circuit to lock the Seakeeper so it cannot precess during ‘lock’ mode or if there is a leak in the circuit or a mechanical problem with the Seakeeper.
Page 10 The brake manifold to remove heat from the brake hydraulic circuit  The Seakeeper enclosure water jackets to remove heat from the flywheel bearings The heated fluid then passes through a thermostat before bypassing or flowing through a heat exchanger that has sea water on the cold side. The circuit also contains a coolant reservoir for coolant expansion and to make filling easy.
Page 11 This section describes operation of the Seakeeper 6 system. Display Screens: Overview 1) When 12 VDC power is applied to the Seakeeper, the display will power up and initialize. The splash screen will be displayed. 2) After the display has initialized, the home screen will be displayed.

The button will change from grey (Stabilize Off) to blue (Stabilize On) Home screen view. These buttons toggle home screen between the Roll Angle Gauge and the Roll Angle Graph as shown below.
Page 13 OPERATION MANUAL SEAKEEPER 6 90403 3 of 6 Section 2: SYSTEM OPERATION The menu bar is used to navigate between pages. From left to right, the available pages are home, settings, information, service and alarm history. The selected page is highlighted in blue on the menu bar.
Page 14 Change the speed of the Seakeeper between normal operation and low power operation. The selected speed is colored blue. When power is cycled (or Seakeeper turned Off), this speed will default back to the normal operating speed. Speed selection buttons shown below are examples and may not match operating speed of installed Seakeeper.
Page 15 Celsius and degrees Fahrenheit. The selected units are colored blue. 6) The information page displays the Seakeeper model, Seakeeper serial number, Seakeeper software versions, RUN hours, and SEA hours, and other information 7) The service page displays operating information from the Seakeeper.
Page 16 3) Turn on the boat’s AC circuit breaker that supplies power to the Motor Drive Box. 4) In most cases, the seawater pump will be wired to turn on when the Seakeeper or Motor Drive Box is turned on. However, in some cases the seawater pump is on a separate AC or DC circuit breaker and it is necessary to turn it on.
Page 17 Seakeeper is available for maximum stabilization. Stabilization To stabilize the boat after Seakeeper is on and above the minimum operating speed: 1) Press the stabilize button. The button will turn blue indicating that the Seakeeper is stabilizing the roll motion.
Page 18 If it is necessary to stop Seakeeper motion for any reason press the stabilize button. The stabilize button will turn grey indicating that the Seakeeper is locked. Never attempt to work on the Seakeeper until the flywheel has stopped spinning.
Page 19 This maximizes life by allowing the Seakeeper to start the coast down cycle before cooling is shutoff. Once the vessel is secured, the AC and DC breakers can be switched OFF. The Seakeeper will continue to spool down to zero rpm. No cooling is required during this time.
Page 20 The Display will indicate 0 RPM when the flywheel has stopped. Note: The seawater pump may run for up to 5 minutes after the Seakeeper is switched off and is coasting (with AC power applied). ...
Page 21 90403 11 of 11 Section 2: SYSTEM OPERATION Speed Adjustment 1) Press the menu button then select the settings screen. 2) Select the desired RPM button to adjust the Seakeeper’s speed. The selected RPM button will turn blue.
Page 22 12 Volts DC powers the Seakeeper Control Box for all the control electronics.  110 - 230 Volts AC powers the Motor Drive Box to drive the motor inside the Seakeeper. These are supplied on Cables 1 and 2 which are shown on Seakeeper drawing 90396, Cable Block Diagram.
Page 23 230 VAC Fluctuation, Spike or Momentary Failure If the AC voltage to the Motor Drive Box is outside Seakeeper’s specified range (110 – 230 VAC), the Motor Drive Box will briefly shut down for protection. The Motor Drive Box will continue operation when the voltage returns to the specified range.

Page 32 Cover Subsystems. Installation Location The Seakeeper is a torque device and does not have to be installed in a specific hull location or on the centerline. However, the Seakeeper should not be installed forward of the longitudinal center of gravity in a planing vessel.
Page 33 A Display with integrated Keypad is used to start, operate, monitor, and shutdown the Seakeeper. Performance Seakeeper reduction of boat roll is a function of the boat’s displacement, transverse metacentric height (GM ) and hull damping as well as the operating conditions (speed and heading with respect to waves) and sea state.
