Premium 2004 Mercury 250 Pro XS Outboard – TorqueMaster Gen 1 Lower Unit – Freshly Built & Ready for Serious Work
Here’s a solid, low-hour 250 Pro XS that’s been gone through carefully and is now looking for its next professional home. Built in 2004 with the respected TorqueMaster Gen 1 lower unit, this engine delivers the classic Mercury performance that commercial operators, charter captains, and heavy-work boat owners have trusted for years.
This 250 hp Mercury Pro XS comes with a fresh rebuild showing only 117 hours on the clock. It features a strong “Gold Block” 3.0L V6 powerhead with excellent compression across all six cylinders (125 psi). All 12 fuel injectors have been professionally flowed and tested, the lower unit is filled with fresh Mercury gear oil, and the 20” midsection is in great shape. No propeller and no controls are included, so you can spec exactly what your boat needs. If you run a charter boat, commercial fishing operation, or a work skiff that demands reliable power and quick hole-shot, this engine is built for the job.

Description
We built this 2004 Mercury 250 Pro XS to run strong and keep running. The powerhead is the desirable Gold Block version with proven durability. Compression sits steady at 125 psi on every cylinder — numbers that tell you the rings, pistons, and valves are in excellent condition.
Every one of the 12 injectors was removed, flowed, and tested so fuel delivery is even and efficient. We drained the old gear oil and filled the TorqueMaster Gen 1 lower unit with fresh Mercury gear lube, giving you peace of mind from the first turn of the key. The 20” shaft length fits most 20–25 ft boats perfectly, whether you’re pushing a loaded aluminum work boat or running a fiberglass center console.
