Frequently Asked Questions
What props help the 400 V10 use less fuel?
Prop pitch and blade area affect slip and burn. Match prop to typical load and cruise speed. Undersized props force higher RPM and hurt economy.
How does sea state change my 400 V10 fuel numbers?
Moderate to rough seas increase hull drag and throttle changes, typically adding 10–20% to hourly burn. Plan extra fuel for safety on longer runs.
Can I rely on GPH at idle for docking?
Idle fuel use is small and varies by alternator load and auxiliaries. For trip planning, focus on cruise data; use onboard instruments for live burn.
