Seakeeper 40 Operation Manual (90716-1)
5.0 Maintenance
5.1 Maintenance Introduction

Due to remote start capabilities of MFDs, ENSURE power removed from Seakeeper and flywheel at zero RPM at display/MFD app before removing covers.
Hydraulic Hand Pump Kit is required for servicing the brake. Pressure should NOT be relieved unless this tool is available.
The Seakeeper system is designed to require as little maintenance as possible. However, since the system is comprised of mechanical and electrical components that operate in a marine environment, some periodic inspections and maintenance are required. Seakeeper recommends a regular inspection interval and Scheduled Maintenance to keep the Seakeeper running trouble-free.
If the Seakeeper is installed in a wet space, efforts should be made to keep the Seakeeper free of salt residue from either condensation or direct exposure to salt spray. If exposed, a regular wipe down with mild soap and water with a rinse will help limit corrosion and keep the Seakeeper assembly in good cosmetic condition. Refer to How to Care for Your Seakeeper article for details.
If any components of the Seakeeper or its sub-systems will be exposed to environmental temperatures where winterization is necessary for storage, reference How Do I Winterize My Seakeeper article.
The Seakeeper comes standard with sealant and thread locker on applicable fasteners. When reinstalling all fasteners use thread locker and sealant unless otherwise specified.

5.2 Scheduled Maintenance Table
This page contains the scheduled maintenance table organized by systems: Mechanical, Hydraulic, Cooling, and Electrical. Perform the Recommended Maintenance after the indicated number of Running [RUN] hours or Years since the last maintenance, whichever occurs first. Scheduled maintenance is not covered under warranty.
Seakeepers are designed for use in a marine environment and to withstand occasional water spray or splash. Prolonged exposure to seawater, however, can cause premature wear and damage to the unit; therefore, it is important to apply a gentle fresh water rinse following exposure to seawater.
The service intervals are based on ‘average’ use, including operating in various Sea conditions, such as zero or low-speed usage in/around marinas and anchorages vs. different speeds while underway in light of heavy sea conditions. If the customer’s normal operating conditions include extended SEA operation, more frequent service should be considered, especially Hydraulic Brake and Cooling service.
- Certain maintenance should be performed by a Seakeeper trained factory technician or trained technician within the Seakeeper Dealer network. Find a local Dealer on our website at www.seakeeper.com/find-us/.
- A Seakeeper technician or Dealer is required to perform a brake service and to replace brake bushings or other brake components. This requires a complete flush, bleed, purge and pressurization of the closed hydraulic system.
- Scheduled Maintenance and the replacement of ‘wear’ items are not covered by the www.seakeeper.com/extended-warranty/recreation-warranty/.
