SeaPro 200-300hp
3.4L V6 and 4.6L V8

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.

Adaptive 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.
160x160_smooth-quiet
Exceptionally Smooth and Quiet
Tuned multi-chamber air intake minimizes airborne noise; fuel injector covers reduce high- frequency noise.
160x160_battery_mangement
Industry-Exclusive Battery Management Technology
When battery voltage decreases, the engine will automatically decrease idle rpm to boost alternator output 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.
160x160_hd_tm_gearcases
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.
Reliability & Durability
The V8 and V6 SeaPro outboards generate ample torque at lower rpm levels, enabling users to work their outboards hard without placing excess stress on the engine.
Lightweight & Compact
Each 200 - 300hp SeaPro CMS (Conventional Midsection) outboard is the lightest engine in its class and is built to handle the demands of commercial applications
High Displacement
The 4.6L V8 225 - 300hp SeaPro outboards boast class-leading displacement, while the 200hp SeaPro features a brawny 3.4L V6 powerhead with plenty of muscle to get the job done.

SeaPro Advantage

Light 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.
