Full throttle RPM range is 5,000–6,000 RPM, and the engine carries a C.A.R.B. 3-Star emissions rating.
Yamaha F250 Electrical, Ignition, and Lubrication
Ignition is handled by a TCI microcomputer system with an LFR6A-11 spark plug, and starting is electric. The alternator delivers 50–70 amp output at wide-open throttle. Lubrication is a wet sump system using Yamalube 4M recommended engine oil, with an oil capacity of 6.3L / 6.0L. Cooling is thermostatically controlled, and recommended fuel filtration is a Yamaha 10-micron fuel/water separating filter (external).
