* Electronic Fuel Injection (EFI): Computer-controlled, electronic fuel injection system automatically adjusts fuel flow and ignition timing for quick throttle response, maximum acceleration, and improved fuel efficiency.
* Yamaha Engine Management System (Y.E.M.S.): An integrated, computerized management system that controls and adjusts such functions as ignition timing, fuel injection mapping, engine diagnostics and off-throttle steering. The OTS function of YEMS activates when the operator releases the throttle lever and attempts to steer the watercraft. This assists the operator in turning while the watercraft is decelerating.
* Traction Control: To manage the awesome power of the GP1300R, Y.E.M.S. utilizes a traction control feature that alters fuel/air mixtures. This system enhances acceleration by reducing prop spin and achieves top end performance by maintaining engine RPM.
* Ceramic-plated Cylinders: Optimal heat transfer, durable, accurate and consistent bore, lightweight.
* Yamaha Loop-charged Combustion: Fuel mixture actually loops as it enters the combustion chamber, which helps distribute fuel/air mixture evenly for better combustion, performance and fuel economy.
* High-performance Tuned Exhaust Pipe and Manifold: The equal flow manifold allows all cylinders to perform equally at peak performance
* Variable Oil Injection: Regulates the fuel/oil mixture to deliver only what is needed at different RPM levels; reduces smoke and oil consumption.
* Corrosion Protection System: Sacrificial zinc anodes protect the engine from harmful galvanic corrosion. Stainless steel fasteners (nuts, bolts, hardware) provide a long service life. Cylinders, cases and heads are all treated with a durable oxide coating to form a barrier between corrosion and expensive engine parts.
