The Beneteau part number 937200 corresponds to a standard M6 x 8mm nylon machine screw (commonly documented in Beneteau parts manuals as “SCREW M MACH NYLON 6 X 8”). On many Beneteau sailboats, these are used as nylon set screws for cutlass bearings where standard steel could cause galvanic corrosion or damage threads.
- Thread Size: M6 (Metric 6mm)
- Length: 8mm
- Material: Nylon (Polyamide), which prevents corrosion in marine environments
- Drive/Head Type: Commonly found as slotted pan head (DIN 85) or standard set screw configurations.
Beneteau part number 937200 is not currently in stock in the US (9/2026) and can be found at many local hardware or fastener stores.
Beneteau 473 Q & A
Question:
I need a replacement Diesel Deck Fill for my 2005 Beneteau 473; please help me identify the part I need.
Answer:
Your 2005 Beneteau 473 original equipment deck fills were manufactured in France by Amiot (now owned by Goiot). Note: Over the past 20+ years, a previous owner may have replaced this part with different specifications.
Factory OEM Replacement Option
If you want a drop-in replacement using the original mounting holes:
- Original Manufacturer: Amiot / Goiot
- OEM Material: Clear Anodized Cast Aluminum or Black Composite (Amiot)
- Standard Hose Diameter: 2″ (55mm) ID Hose or 1-1/2″ (37mm) ID Hose (Note: Beneteau used 50mm / ~2″ hose on most large 40ft+ diesel fills of that era, but double-check your existing hose inner diameter before ordering).
- Sourcing OEM Parts: We are not aware of a direct-replacement Amiot deck fill.
Standard Aftermarket Replacement Options
Beneteau replacement Part #208465, 8-point star socket in the center, designed to be turned using a standard winch handle or deck filler star key. The red ribbed body indicates it connects to a diesel fuel fill line, with an attached black splash-guard / anti-lost grid (lanyard retainer) designed to sit inside the fill pipe; This deck filler assembly uses a combination of marine-grade materials built for UV, corrosion, and chemical resistance:
Anti-Lost Lanyard Retainer (Grid): Black plastic / composite polymer mesh designed to sit inside the fill pipe.see photo below:
Outer Ring/Flange (Top Rim): Polished 316L Stainless Steel (Inox) for maximum marine corrosion resistance and flush-mount aesthetics.
Inner Cap Insert & Threaded Body: Glass-reinforced polyamide (nylon) / heavy-duty polymer resin, molded in black and red for chemical resistance against diesel fuel.

If you prefer upgrading to 316 Stainless Steel (which won’t oxidize like cast aluminum or fade like plastic/composite):
- Sea-Dog / Perko / Whitecap 316 Stainless Steel Deck Fill
- Size needed: Matches your existing hose diameter (typically 1-1/2″ or 2″ ID).
- Flange Size: Standard 3-1/2″ overall diameter with 3 countersunk mounting holes.
- Installation Tip: Aftermarket fittings often have a slightly different screw-hole circle pattern compared to European Amiot patterns. You will likely need to plug the existing screw holes with epoxy and re-drill new pilot holes.
Key Verification Steps Before Ordering
- Hose Inside Diameter (ID): Measure the interior diameter of your existing diesel fuel hose attached beneath the deck (either 1-1/2″ or 2″).
- Cap Key Type: The factory Amiot diesel cap uses a standard winch handle (11/16″ square/octagonal) or winch handle key to open. If your cap opens using a 2-prong spanner key instead, a previous owner may have already swapped it out.
- Flange Bolt Pattern: Measure center-to-center distance between screw holes to confirm if an OEM Amiot unit will align without modification.
