Maintenance Schedule

Seakeepers are designed to require minimal maintenance since most of the critical components operate in a sealed enclosure, protected from the corrosive moisture involved with life on the water. Outside of the sphere, the closed-loop hydraulic circuit and the cooling circuit should be periodically inspected.

Perform the Recommended Maintenance after the indicated number of Running [RUN] hours or Years since last maintenance, whichever occurs first.

The single cylinder hydraulic brake systems on the Seakeeper 1, 4, 4.5, 10.5, and 14 require minimal service with only an inspection every 12 months, and a bushing replacement every 2000 hours.

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 or heavy sea conditions. If the customer’s normal operating conditions include extended SEA operation, more frequent service should be considered.
