The 2019 Yamaha F300 is a powerhouse 4.2-liter V6, 4-stroke outboard. A twin-engine setup is highly sought after for large offshore fishing boats and high-speed cruisers. It features electronic fuel injection (EFI) and a high-output alternator<\/strong><\/p>\n

Performance & Fuel Economy<\/h1>\n

On a properly propped twin setup (often pushing 30-foot+ boats), the fuel efficiency is impressive for an engine of this size. At a comfortable cruise around (3500 – 4000 RPM) you can expect to burn roughly 10 to 13.5 gallons per hour (GPH) per engine. Top speeds will heavily depend on your boat’s hull design and weight, but twin 300s easily propel most offshore center consoles well into the 50-60+ mph range<\/strong>.<\/p>\n
