OVERVIEW
MULTI-POINT ELECTRONIC FUEL INJECTION
- Multi-point Precision Electronic Fuel Injection is controlled by the Engine Control Module, which continually adjusts the fuel/air mix to match engine load and speed.
PLASMA-FUSED SLEEVELESS CYLINDER
- Plasma-fused sleeveless cylinders allowed us to enlarge cylinder bores without increasing cylinder dimensions.
BLOW-BY GAS REBURNING SYSTEM
- Removes any oil in the blow-by gases and returns only the fuel to the combustion chamber through the intake system, keeping the exhaust gases clean.
SHALLOW WATER DRIVE
- The outboard can be set at a tilt angle, preventing it from hitting the bottom when operating in shallow water.
