Prop testing today - 47 gps mph with a 17p but 6500 rpm; 49 gps mph with a 19p but 6100 rpm; shop is getting a 18p to try for 6300 rpm. Started chine walking with the 19p. All props 3 blade. Engine height looks good. Boat was light - only 35 gallons of gas and two regular size people. Best it ever did with the 250 OX66 was 42 gps mph with 17p at 5600 rpm. I'm hoping it will be pretty economical at cruise.
