Am thinking of buying a Chris Craft 460 Corinthian w/ 410 hp engines. Is there an past or present owner that tell me how much fuel this yacht burns at various rpm's.
If you're cruising at 8 knots maybe. However at around 3300 - 3400 rpm cruising up on plane I would expect 16 to 18 gph per side, so a total burn of 32 to 36 gph. Fuel cost was of little concern in those days.
