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.
Efficient All-Around Performance: A host of efficiency-enhancing features such as Advanced Range Optimization (ARO), a closed-loop fuel system and a hydrodynamic gearcase optimize fuel economy so you can get more done on every tank. 87-Octane: SeaPro outboards are calibrated to deliver full performance on 87-octane fuel, while a boat-mounted water-separating fuel filter kit helps prevent fuel-related issues. Compact Flexibility: V10, 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. High-Output Alternators: To help support a heavy load of onboard accessories, SeaPro outboards feature powerful alternators, including a 150-amp alternator on the 350hp engine.
