Intuitive, Innovative Features
Adaptive Speed Control
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.
SeaPro Performance Data
Exceptionally Smooth & Quiet
Precision-tuned intake and exhaust, combined with fuel-injector covers, minimize noise for more comfortable all-day operating. V8 and V6 models are 15-30% quieter than a leading four-stroke competitor, while the V10 model is 28% quieter at cruise than a leading competitor.
Lightweight & Compact
Each SeaPro Conventional MidSection (CMS) 200-300hp model is the lightest engine in its class and is built to handle the demands of commercial applications.
High Displacement
V10 and V8 SeaPro outboards boast class-leading displacement, while the 200hp SeaPro outboard features a brawny 3.4L V6 powerhead with plenty of muscle to get the job done.
