The 2015 Mercury OptiMax Sport XS 250 Outboard Motor is a used high-performance marine engine advertised with approximately 143 hours, a Mercury Racing SportMaster lower unit, a Detwiler hydraulic jack plate, and a stainless-steel propeller. The seller reports that the motor has zero known issues.
Designed for performance-oriented boating, the Mercury Racing 250XS OptiMax combines 250 horsepower with a two-stroke direct fuel injection system. Its high-output V6 configuration is engineered for responsive acceleration, strong power delivery, and performance applications where a suitable boat and properly matched setup are essential.
The OptiMax direct fuel injection system uses electronically controlled fuel delivery to support combustion and engine performance. The Mercury Racing 250XS platform was developed for demanding applications where throttle response, power delivery, and suitable propeller and gearcase selection are important.
This package includes a SportMaster lower unit, according to the seller. The SportMaster gearcase is associated with performance-oriented marine applications and is designed for compatible engine and boat configurations. Its condition, service history, gear ratio, and suitability for the intended application should be confirmed before purchase.
The advertised package also includes a Detwiler hydraulic jack plate and a stainless-steel propeller. A hydraulic jack plate allows the operator to adjust engine mounting height for suitable operating conditions and boat setups. The stainless-steel propeller provides the propulsion component needed for the advertised package, although its pitch, diameter, model, and condition should be verified.
With approximately 143 hours, this engine may be worth considering for buyers seeking a used performance outboard with valuable installation hardware included. The seller reports no known issues, but engine condition should be independently verified through a marine inspection and appropriate operational testing.
Before purchase, confirm the exact engine model code, shaft length, serial number, operating hours, service history, compression or leak-down results where appropriate, lower-unit condition, and the specific components included in the sale.

Why Choose the 2015 Mercury OptiMax Sport XS 250 Outboard Motor?
The 2015 Mercury OptiMax Sport XS 250 Outboard Motor is an option for boat owners looking for high-output two-stroke performance with additional hardware included in the advertised package.
Its 250HP V6 engine is designed for compatible applications requiring substantial power. Mercury Racing’s SportMaster gearcase platform is associated with performance-focused setups, while the hydraulic jack plate and stainless-steel propeller offer useful components for a properly matched installation.
The advertised 143 hours provide an indication of the seller-reported operating history, but hours alone do not establish engine condition. Maintenance records, storage history, diagnostic checks, and inspection of the engine and lower unit are important when evaluating a used high-performance outboard.
The included hydraulic jack plate and propeller may provide added value compared with buying a motor alone. Buyers should confirm their exact specifications, condition, and compatibility with the intended boat.
Mercury OptiMax Direct Fuel Injection
The Mercury 250XS OptiMax uses a two-stroke direct fuel injection system rather than a conventional four-stroke engine design.
OptiMax technology uses electronically controlled fuel delivery and a pressurized air system to support combustion and operating efficiency. The engine’s maintenance requirements differ from those of a four-stroke outboard, so buyers should follow the applicable Mercury Racing owner’s manual for fuel, oil, servicing, and storage procedures.
The specified fuel and oil requirements should be confirmed against the exact engine serial number and regional manual.
SportMaster Lower Unit
The seller identifies the lower unit as a Mercury Racing SportMaster.
The SportMaster gearcase is designed for compatible performance applications where gearcase selection, propeller matching, engine height, and hull characteristics work together. Its suitability depends on the specific engine, shaft arrangement, boat design, and intended use.
Before purchasing, inspect the gearcase for leaks, impact damage, corrosion, abnormal noise, and other signs of wear. Ask for confirmation of the gear ratio, service history, and exact gearcase model.
Detwiler Hydraulic Jack Plate Included
The advertised package includes a Detwiler hydraulic jack plate.
A hydraulic jack plate allows engine mounting height to be adjusted for compatible hull designs and operating conditions. Correct setup can affect handling, propeller performance, water pressure, and engine operating behavior.
Confirm the jack plate’s model, setback measurement, adjustment range, hydraulic condition, mounting hardware, and compatibility with your boat and engine. Verify whether its controls and hydraulic components are included and operational.
Stainless-Steel Propeller Included
The seller states that a stainless-steel propeller is included.
Propeller selection is important for achieving suitable engine RPM, acceleration, speed, and handling. The correct pitch and diameter depend on the boat’s design, load, gear ratio, engine height, and intended use.
Request the propeller’s manufacturer, model, pitch, diameter, and condition before purchase. Inspect the blades for damage, deformation, corrosion, or previous repairs.
Approximately 143 Engine Hours
The engine is advertised with approximately 143 operating hours.
The reported hours should be verified where possible using the engine’s available records or diagnostic information. Buyers should also request maintenance invoices, details of previous use, storage history, and any information about repairs or replaced components.
Because a used performance outboard may have been operated at varying loads and speeds, engine hours should be considered alongside service history and an independent condition assessment.
Reported Mechanical Condition
The seller reports that the engine has zero known issues.
This is a seller statement, not an independently verified mechanical assessment. Before completing the purchase, consider a marine-engine inspection that includes appropriate compression or leak-down testing, diagnostic checks where supported, cooling system operation, fuel delivery, charging output, and an assessment of the lower unit.
A controlled operational test may provide additional information about starting, idle stability, throttle response, shifting, warning systems, and cooling-water flow. Follow Mercury’s testing procedures and ensure the engine is operated safely.
Ideal Applications
The Mercury Racing 250XS OptiMax may suit compatible performance fishing boats, bass boats, performance-oriented recreational vessels, and other craft designed for a 250HP outboard and the exact engine configuration.
Always verify the boat manufacturer’s maximum horsepower rating, transom requirements, engine weight limits, steering arrangement, shaft length, and compatibility with the SportMaster lower unit and hydraulic jack plate.
