OVERVIEW
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.
