Mercury / Mariner WMH V6 Carburetor Set
Three-carburetor set off a Mercury / Mariner V6 outboard, WMH shared-body family. Top, middle, and bottom positions all included. Rebuild before installing — jets and reeds set the HP, see the HP note below.
Part Numbers
Carb Stamps:
| ▸ | WMH-1 and WMH-2 — mixed stamps across the three carbs (see photos for the actual stamp on each) |
OEM Part Numbers:
| ▸ | 818650A38 — current Mercury supersession |
| ▸ | 818650A8 — superseded by 818650A38 |
| ▸ | 9672A32, 9672A42, 9672A5 — earlier numbers in the chain |
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. Two WMH carbs that look identical can be calibrated for different HP.
This set was assembled from inventory and the original donor motor 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 — bowls opened and inspected, clean inside |
| ▸ | Black plastic fitting has a crack — should not affect performance (see photos) |
| ▸ | Sold as-is — rebuild and rejet to your HP before installing |
| ▸ | You receive everything pictured — please review the photos |
Fitment
| Years: | 1990 — 1995 |
| Models: | Mercury and Mariner V6 outboards using the WMH carburetor (135, 150, 175, 200 HP and Jet 105 / Jet 140 variants) |
| Engine: | V6 2-stroke, carbureted |
Verify by part number or carb stamp before purchasing — the WMH stamp family is specific to the 1990-1995 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.
