Regular freshwater rinses: The key to longevity

Have you ever noticed the impact of prolonged exposure to salt on metal surfaces? Of course, it leads to corrosion. The same principle applies to your Seakeeper. Regular freshwater rinses are crucial to remove salt deposits and prevent surface corrosion, thereby prolonging the life of your Seakeeper stabiliser.

Prolonged exposure to seawater can cause premature wear of your Seakeeper. Therefore, it is highly recommended to rinse it with fresh water following exposure. This simple procedure can counteract the corrosive effects of salt and contribute significantly to your Seakeeper’s longevity.

When to rinse

As a rule of thumb, rinse your Seakeeper with fresh water as soon as possible after exposure to saltwater. This immediate action helps prevent the onset of corrosion and damage, ensuring that your Seakeeper can withstand the occasional spray of saltwater.

Consider implementing freshwater rinses into your routine - do it intermittently, or even better, at the end of a day spent at sea. This timely action can prevent corrosion buildup and keep your Seakeeper in optimal condition.

Rinsing technique

Now that we understand the importance of rinsing, let’s discuss the appropriate way to do it. Directing a forceful stream of water at your Seakeeper is not advisable. Instead, use a gentle spray to avoid any potential damage, as it is designed to withstand occasional spray.

A wide-spread water pattern is recommended when rinsing, to prevent direct hits on sensitive electrical components. For an effective rinse, use a balanced solution of water and a salt-away product in a pump sprayer. Think of it as giving your Seakeeper a gentle shower, similar to an outboard motor’s rinse after saltwater use. Be sure to cover all surfaces like brake calipers, pads, and rotors to remove salt deposits.

Drying process

After the rinse, it’s time to dry your Seakeeper - and no, leaving it to dry on its own isn’t enough - you need to thoroughly dry the gyro stabiliser components to remove all moisture.

Pay attention to the following steps to effectively dry your Seakeeper stabiliser and prevent premature wear:

  1. Rinse all metal surfaces and cables thoroughly.

  2. Dry the stabiliser completely to prevent corrosion and other damage.

  3. Ensure that your Seakeeper is well-ventilated to aid in the drying process.

Following these steps will help maintain the longevity and performance of your Seakeeper stabiliser.

Annual maintenance schedule: Protecting your investment

Your Seakeeper is a significant investment, and it deserves to be treated as such. An annual Seakeeper service is crucial to maintain its peak performance and includes a comprehensive review and maintenance of the unit’s components. These maintenance tasks include checking and servicing the electrical, hydraulic, and cooling systems, inspecting the foundation, and ensuring proper torque on all mounting bolts, among other essential checks.

In places like Fort Lauderdale, known for its maritime services, recreational boat owners can access comprehensive annual services for their Seakeeper, which includes a thorough inspection of the brake, cooling, electronic, and mechanical foundational systems. However, depending on the use intensity and sea conditions, some Seakeeper units might require more frequent services. At Aquamare we are proud specialists of Seakeeper products, vastly experienced with all types of units and maintenance tasks we will keep you running smoothly and safely on the water.

Hydraulic and cooling system care

The hydraulic and cooling systems are crucial parts of your Seakeeper, and they need your attention during the annual maintenance. Inspecting the hydraulic cylinders, hoses, and heat exchanger, as well as checking subsystems for issues, are essential tasks for maintaining these systems.

The cooling system’s care requires a closed-loop maintenance approach, which includes cleaning, descaling the heat exchanger, and ensuring there is proper seawater flow throughout the cooling system. Also, the zinc anode in specific Seakeeper models should be replaced every 150 hours or every 3 months, as part of the maintenance schedule, something we at Aquamare have vast knowledge and experience undertaking.

Brake service and inspection

The brake system is a vital part of your Seakeeper, and it needs careful inspection and service. During the annual service, brake service is performed by removing and replacing accumulators as part of the maintenance routine.

The inspection of the Seakeeper’s brake system should include the following:

  • checks for abnormal noises

  • commutator condition

  • tightness of electrical connections

  • regular grease replacements

These steps ensure that your Seakeeper’s brake system is always in top condition.

Visual inspections for Seakeeper components

Periodic inspections between services

While professional services are crucial, you also need to conduct regular checks of your Seakeeper’s external systems in between these services. Since most critical components are housed within a sealed enclosure, these checks are necessary.

Perform systematic inspections of the accessible external parts of the Seakeeper to detect any anomalies. Incorporating these checks into your boat’s maintenance routine ensures your Seakeeper’s longevity and functionality. Plus, these routine checks can help reduce your overall maintenance needs.

Visual inspections

Visual inspections are an integral part of your Seakeeper’s maintenance. You should include checking for:

  • every three months, check the Seakeeper’s actuators for anode wear

  • ensure the integrity of the unit’s seal against environmental elements such as dust and water during these visual inspections.

Functional tests

Functional tests are as crucial as visual checks. They help verify the operating condition of control valve microswitches, foot and hand brake switches, and main controller settings. These tests help you ensure that all the switches and settings are working as intended and that your Seakeeper is ready for its next adventure.

Seakeeper-specific considerations

Every Seakeeper model is unique, designed with advanced technology such as vacuum encapsulation and water cooling systems to cope with the harsh marine environment. Therefore, it’s essential to understand the specific maintenance requirements for your Seakeeper model.

For instance, Seakeeper models 1, 4, 4.5, 10.5, and 14 with a single cylinder hydraulic brake system need a bushing replacement every 2000 hours of operation. And larger models like the Seakeeper 26, 35, and 40 involve additional checks on:
