short description
TorqueMaster transmission
The lightweight TorqueMaster transmission (on select V8 models) features a 1.75:1 gear ratio and a heavy-duty 1.25-inch diameter driveshaft designed for use at medium speeds.
Adaptive Speed Control
Thanks to Adaptive Speed Control, the new SeaPro engines maintain a desired torque regardless of changes in load or conditions without adjusting the throttle position – a first for the outboard industry.
performance-optimized exhaust
The sound of the exhaust system has been optimized so that it sounds unmistakably full on the water, but is still quieter than other high-performance engines.
Transient Spark technology
Transient Spark technology electronically adjusts the engine's ignition timing when necessary. This subtle, automatic modification generates additional torque for quicker acceleration and higher acceleration.
Additional charging power
A powerful generator delivers a net charging power of 20 amps at idle and 85 amps at wide open throttle. Battery management automatically increases idle speed with idle charging to increase output power and charge weak batteries.
