Fitment and Purchase Checks
Mercury and Mariner V6, 135 to 250HP, 1996 and up. XR6, Magnum III, Pro Max, OptiMax 135 to 175. Two wires only. A three-wire black, green, blue harness does not use this unit. Early cartridge pump motors from the 1980s and early 90s are a different design. No fit. The 250 and the XR6 both take this motor. OptiMax DFI is not covered here.
Why This Unit
A V6 trim motor works hard. Every tilt pulls full current through the brushes. Case sits right where the spray hits. Seal fails, and the first sign is a slow trim or a blown fuse. Ours has a sealed case, copper windings, coated armature. Two-bolt flange matches the original pump. Nothing to drill.
For Buyers and Distributors
Six months warranty. 20 pieces minimum. Ships in 10 to 15 days. RoHS, REACH and ISO9001 papers on file. Tell us the engine model, the old number, the quantity and the port. Quote goes back same day.
