SeaPro™ 200-350hp

5.7L V10, 4.6L V8 and 3.4L V6

Every day, even in the toughest conditions, SeaPro high-horsepower outboards are built to tackle the biggest jobs. They feature heavy-duty components designed to work as hard as you do, with unmatched corrosion resistance to go wherever the task takes you.

Intuitive, Innovative Features

Adaptive Speed Control

Maintain engine rpm despite changes in load or conditions, with no throttle adjustment.

Industry-Exclusive Battery Management Technology

When needed, the idle charge battery management system works for you by monitoring battery voltage and adjusting engine rpm at idle to boost alternator output.

Easy to Maintain

The industry-exclusive top-cowl access door eliminates hassle, allowing you to check or top off oil without removing the cowl. And gearcase oil can easily be drained from the torpedo.

Heavy Duty Gearcase

SeaPro gearcases are validated at three times the lifespan of a recreational gearcase. The V10 SeaPro engine features an all-new rugged gearcase with advanced hydrodynamics for control, efficiency and durability.

Reliability & Durability

High-horsepower SeaPro outboards generate ample torque at lower rpm levels, enabling operators to work their outboards hard without placing excess stress on the engine.
