Perkins 4-236 Fuel Consumption

Here are several pages from Dawn aboard Lady Hawk regarding the fuel consumption for a Perkins 4-236.  Note that several members have commented that their consumption is much less than the Perkins data indicates.  With an 18" or 19" prop, unspecified pitch and 1800 rpm, approximately 7 - 7.5 kts is expected in no/low seas and no current.The Perkins power curves indicate maximum continual rpm to be 2250 and intermittent, 2500.

Thanks to Dawn and Patrick O'Donnell for obtaining and distributing the information.
