Mercury - SeaPro 300 AMS

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.

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 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.

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.

• 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.
• 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.
• 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.
• 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.
