Preventive Marine Maintenance

Maintenance Guide: 4 Steps to Extended Lifespan

By following Freeman’s recommended service procedures, watertight integrity and smooth mechanical operation are preserved even in harsh sea environments.

STEP 01

Wash & Deoxidation

Rinse away salt deposits using fresh water and mild soap (pH 6–8). Remove stubborn marine oxidation with acid-free aluminum cleaner and a non-metallic scrub pad.

Aluminum Care →

STEP 02

Gasket Inspection

Inspect neoprene seals for hardening, tears, or compression set. Clean the channel thoroughly and use approved contact adhesive when replacing. Protect against freeze adhesion.

Gasket Care →

STEP 03

Mechanism & Grease

Lubricate dogs, linkages, and central spindle with biodegradable marine grease (Vickers EP2). Penetrating bio-spray frees stiff or salt-encrusted pivot joints.

STEP 04

Coaming & Anti-Seize

Inspect coaming knife-edges and scuppers. For bolted installations, always coat stainless fasteners with ceramic anti-seize paste to eliminate galvanic pitting completely.

Technical Support & Advice

Frequently Asked Questions: Maintenance & Installation

How often should a Freeman deck hatch be serviced and lubricated?

In commercial vessel operations (SOLAS), visual inspection and lubrication are recommended every 6 months, along with an annual chalk test to verify watertight integrity. For leisure craft, pre-season fitting out and winterization checks are recommended. Lubricate linkages with biodegradable marine grease (Vickers EP2) and protect the gasket with silicone stick to prevent drying and freeze adhesion.

Which adhesive should be used when replacing a neoprene gasket?

Only approved polychloroprene contact adhesive (Crosseven Contact Adhesive) should be used. Standard cyanoacrylates (superglue) harden and crack during thermal expansion, while silicone lacks shear strength against marine aluminum. The channel must be mechanically cleaned and thoroughly degreased with heavy-duty wipes before applying a uniform, thin layer to both mating surfaces.

Why is the handle or dogging mechanism stiff to operate?

Stiff mechanical operation is almost invariably caused by old, dried grease combined with salt encrustation inside the spindle sleeve or on wedge contact dogs. First rinse with fresh water and apply penetrating bio-spray (Vickerlube Bio WDF) to dissolve deposits. Once smooth operation is restored, pack pivot linkages with fresh EP2 marine grease.

How do you prevent galvanic corrosion during bolted coaming installation?

When 316 stainless steel fasteners are mounted through aluminum coamings, electrolyte ingress triggers galvanic degradation of the aluminum. To isolate the metals, coat all fastener threads and shanks with metal-free ceramic paste (CRC Ceramic Paste Anti-Seize). Seal the perimeter deck joint with UV-stable STP polymer sealant (Sikaflex 591) to create an impervious barrier.

Which cleaning agents are safe for marine aluminum (pH limits)?

Marine-grade aluminum relies on a natural passive oxide film requiring chemistry within pH 4.5–8.5. Aggressive alkaline degreasers (pH > 8.5) and chlorine-based cleaners strip this barrier, inducing pitting corrosion. Use pH-neutral boat wash for regular cleaning. For heavy weathering, apply Star brite Aluminum Cleaner followed immediately by PTFE polish to restore protective surface sealing.
