Mercury SeaPro V-8 250 HP - 20 in. Shaft

Commercial calibration meets commercial duty cycles, delivering more power with less engine stress. Unmatched corrosion resistance starts with superior aluminum alloys and coatings, plus four serviceable anodes, including one in the cylinder block. All to deliver an engine that works as hard as you do.

Intuitive, Innovative FeaturesAdaptive Speed Control: Maintains a desired rpm regardless of changes in load or conditions without adjustments to the throttle level position - a first for the outboard industry.Exceptionally Smooth and Quiet: Tuned multi-chamber air intake minimizes airborne noise; fuel injector covers reduce high - frequency noise.Industry-Exclusive Battery Management Technology: When battery voltage decreases, the engine will automatically decrease idle rpm to boost alternator outbput and recharge low batteries to the proper level, protecting operators from draining their battery while trolling.Easy to Maintain: The exclusive Top Cowl Service Door simplifies routine maintenance, letting you check or add engine oil without removing the top cowl. Hour-based maintenance schedule decal is located under the cowl, providing a quick overview of routine maintenance.Heavy Duty Gearcase: All V8 and V6 SeaPro outboards feature a heavy-duty gearcase validated at three times the lifespan of a recreational gearcase. The SeaPro gearcase was designed with easy maintenance in mind: Oil can be easily drained from the gearcase torpedo.SeaPro AdvantageLight and Mighty: Less weight means more efficiency. The V6 200hp SeaPro is the lightest engine in its class. A combination of ample torque and less weight makes these outboards ideal for heavier loaded boats.Maximum Durability: V8 and V6 SeaPro outboards feature a heavy-duty gearcase that is validated at three times the lifespan of recreational gearcase and slips easily through the water, decreasing workload on the engine.Reduced Fuel Cost: Advanced Range Optimization (ARO) and closed-loop fuel control on the V8 and V6 SeaPro outboards precisely adjust the fuel mixture for optimal fuel economy.Compact Flexibility: The V8 and V6 SeaPro outboards mount on 26-inch centers, making them ideal for a broad range of multi-engine applications and simple, seamless repower rigging.SpecificationsHorsepower: 250Full throttle RPM: 4800-5600Engine type: V8Displacement (CID/CC): 279 CIDDisplacement (L): 4.6LCylinder Configuration: V-8 [64 degree] with Dual Overhead Cam [DOHC] and 32-valvesStarting: Electric Start with SmartStart ProtectionGearcase ratio: 1.75:1Alternator amp / Watt: 85-amp (1071 Watt) with Idle ChargeTrim system: Power trim and tiltDry weight *Lightest model available: 527 lbs / 239 kgsSteering options: Big Tiller (optional); Hydraulic (standard); Power (optional)Shaft length: 20" / 508 mm
