Note on Beneteau Bearing Types: Beneteau powerboats and sailboats predominantly use metric shafting. Unlike standard American brass-shelled cutlass bearings, Beneteau frequently utilizes flanged nitrile/EPDM rubber sleeve bearings or phenolic/composite sleeves secured via non-metallic grub screws through the shaft strut.

Important Fitment & Maintenance Tips

  • Verification by HIN: Engine options on certain models (e.g., Swift Trawler 34/35) varied depending on whether a single Yanmar, Cummins, or Volvo Penta engine option was selected. Always measure the shaft diameter with a digital caliper or confirm with Beneteau using your Hull Identification Number (HIN) prior to ordering.
  • Outer Diameter (OD) Variance: Ensure you verify the strut bore diameter before fitting. Depending on whether your boat uses an all-rubber flanged bearing or a metallic/composite sleeve, the required outer diameter and stern log tolerances can differ by $1\text{–}5 \text{ mm}$.
  • Fasteners: When replacing Beneteau OEM rubber/composite bearings, always replace the nylon/plastic grub locking screws included with the bearing to avoid damaging the strut threads.
