Spare Parts for Freeman Marine Model 1218 Oval Deck Hatches (12" x 18" / 305 x 457 mm)

Welcome to Bövik Marin AB – authorized European supplier of genuine factory replacement parts for Freeman Marine Model 1218 oval cast deck hatches. Offering a 12 x 18 inch (305 x 457 mm) clear opening, Model 1218 is the ideal oval utility hatch specified where deck framing or longitudinal stringers restrict cutout dimensions, providing streamlined access to lazarettes, fuel tanks, steering compartments, and storage lockers across workboats, commercial vessels, and motor cruisers.

Model 1218 is manufactured exclusively with Freeman's proven compression sealing design (raised smooth spigot coaming, Series 2431 lift-out and Series 2471 hinged), allowing decks to be washed down effortlessly without debris traps or drainage hoses. Mechanically, the hatch operates via four 7.75-inch aluminum dog arms driven by a central 4-hole cam hub, delivering positive watertight compression in less than a quarter-turn of the flush deck handle.

Below you will find all genuine mechanical and elastomeric components required for scheduled maintenance, survey overhauls, and complete mechanism rebuilds for Model 1218:

Technical Guide: Maintenance and Component Specification for Freeman Model 1218 Oval

The oval geometry of Freeman Model 1218 (Series 2431 & 2471) provides an outstanding balance between compact deck cutout width and generous access length. Unlike the larger Model 1524 which is produced in two distinct sealing technologies, Model 1218 is built exclusively with compression sealing.

1. Compression Gasket Specification (Part no. 9801-2003)

  • Continuous Molded Elastomer Ring: The Model 1218 gasket is manufactured as a seamless continuous oval ring in marine-grade EPDM/neoprene. It features a solid planar cross-section precision engineered to mate against the coaming's raised smooth spigot.
  • Universal Across Coamings & Hinges: Part no. 9801-2003 is the universal gasket whether your coaming is fabricated in aluminum, steel, or stainless steel, and fits both lift-out covers (Model 1218) and hinged variants (Model 1218-H).
  • Installation Procedure: Clean the cover channel thoroughly of dried salt crust and old adhesive before seating the replacement gasket. Seat the continuous ring evenly into the channel without stretching the elastomer around the end radii.

2. 4-Arm Kinematics with 7.75" Dog Arms

Model 1218 operates via Freeman's central 4-hole marine aluminum cam hub (Part no. 0011-2002) and four 7.75-inch aluminum dog arms (197 mm, Part no. 0211-2007). Because the hatch is oval, the dogging linkages are angled to distribute uniform perimeter compression across both long sides and rounded end arches. Inspect nylon cam buttons (Part no. 0621-2004) during servicing and lubricate hub tracks with high-adhesion marine grease.

3. Center Bushing & Spindle Sealing

Moisture weeping beneath the flush deck handle indicates worn spindle O-rings. Model 1218 utilizes Freeman's heavy-duty Universal Center Bushing Overhaul Kit (Part no. 0031-2204), containing a marine-grade sleeve bushing, dual O-rings, and stainless roll pin. Always coat O-rings with waterproof marine grease during reassembly.
