Mercury / Mariner WMH V6 Carburetor Set

| ▸ | WMH-5 — family stamp |
HP Note — Read Before Buying
The WMH carburetor body is shared across Mercury V6 outboards from 135 HP through 200 HP. The HP rating is determined by the jet kit, reed cage, and internal calibration — not by the carb body itself.
The original donor motor for this set is not confirmed, so we cannot verify the as-delivered jet calibration. Plan to rebuild this set with a kit matched to your engine's HP rating before installing.
Condition
| ▸ | Used set in good condition — cleaned for sale |
| ▸ | Sold as-is — rebuild and rejet to your HP before installing |
| ▸ | You receive everything pictured — please review the photos |
Fitment
| Year: | 1990 |
| Models: | Mercury and Mariner V6 outboards using the WMH carburetor (135, 150, 175, 200 HP) |
| Engine: | V6 2-stroke, carbureted |
Verify by part number or carb stamp before purchasing — the WMH stamp family is specific to the 1990s carbureted V6 era. Does not fit EFI V6, Optimax DFI, or Verado motors. Note that 1990-1992 200 HP applications used a different reed cage configuration — verify your engine's reed cage matches before installing.
