⚠ Mercury 40-115 HP — Which Gearcase Do I Have?

Mercury makes two different gearcase sizes for the same HP range. Choosing the wrong one means the guard won't fit.

  • Small gearcase (3.44") — Standard 40-60 HP → Use 27341
  • Large gearcase (4.25") — Bigfoot / Command Thrust / SeaPro 40-60 HP → Use 27071
  • Standard gearcase — 75-115 HP (before 2015) → Use 27071
  • Standard gearcase — 75-115 HP 4-Stroke (2015+) → Use 27061
  • 4.8" torpedo gearcase — Command Thrust / Verado / ProXS 75-300 HP → Use 27211

Tip: Check the sticker on your lower unit or measure the torpedo (gearcase) diameter to confirm.
