You should burn roughly 1 gallon per hour for every 10 horse power. 10 hp engine shoud burn about 1 gallon an hour. 40 hp should burn about 4 gph. These are at planing speeds or throttle settings. I run my 150 OMC Ficht at about 3900 RPM's and it burns roughly 8-9 gallons per hour. It will burn about 15 gallons per hour at 5300 rpm's. This is on a 22' Wooldridge and at 3900 rpm's it is doing right about 35 mph with a 19" pitch prop.
