Seakeeper 2 Operation Manual (90489-2); S/N 2-203-0400 to 2-232-1563
Maintenance
Maintenance Introduction
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 Fresh Water Rinse article on www.seakeeper.com, 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 Seakeeper Winterization Process article on www.seakeeper.com.
The Seakeeper comes standard with sealant and thread locker on applicable fasteners. When reinstalling all fasteners use thread locker and sealant unless otherwise specified.
