Frequently Asked Questions
Does the 500R's high-output tune change cruise economy?
High‑output calibrations emphasize top‑end power. At steady mid‑range cruise, economy can still be optimized via prop pitch, hull trim, and load distribution.
What safety margin should I plan for at speed?
For performance runs, plan 20–30% extra fuel due to throttle variability and sea state. Monitor fuel‑per‑mile with onboard displays when available.
Are premium fuels required for best efficiency?
Use the specified octane and additives. Proper fuel helps maintain intended ignition timing and knock margins, improving performance and efficiency.
