The impressive muscle of our new V-8 4.6-liter and V-6 3.4-liter powerheads is specifically designed for commercial duty and delivers our best-ever fuel economy.
V-8 CMS models feature a higand V-6 SeaPro h-output alternator that delivers 20 amps net
at idle and 85 peak amps, while the V-8 300 hp SeaPro AMS (Advanced MidSection) engine boasts a class-leading 115-amp alternator.
Idle Charge battery-management
When battery voltage decreases, the engine will automatically increase idle rpm to boost
alternator output and recharge low batteries to the proper level, protecting operators from
draining their battery while trolling.
The new SeaPro also features a heavy-duty gearcase validated at three times the lifespan of a recreational gearcase. Convenient gearcase oil drain: Oil can be easily drained from the gearcase torpedo.
The new V-8 4.6 L 225-300 hp SeaPro engines boast class-leading displacement, while the
new 200 hp SeaPro features a brawny V-6 3.4 L powerhead with plenty of muscle to get the job done. And each Conventional MidSection (CMS) 200-300 hp model is the lightest engine in its class. All V-8 and V-6 SeaPro engines are extremely compact and light yet deliver ample torque that makes these outboards ideal power for heavily loaded boats.
