Other innovative design features include a high output, marine-style alternator located beneath the flywheel. It puts out 32 amps at 1000 rpm, and 45 amps from 2000 rpm up. A blow-by gas re-burning system removes oil from the blow-by gas, returning only gasoline to the combustion chamber, which helps the engine run very clean. And, an Idle Speed Controller, which is controlled by the ECM, makes starting easier and stabilizes the engine at idle and while slow trolling. The F225 and F200 are available in 25- and 30-inch shaft lengths, with counter-rotation models available, and come with standard three-year limited pleasure-use warranties.
