I just got a 15' tri hull boat with a 1984 johnson 85HP on it. I took it out for the 2nd time yesterday and burned 9gal in about 2 hours at 3/4 throttle most of the time. dont know alot about the motor and the propeller is a 19X13. my friends boat was with me with a 80's model 70hp johnson on a 17' tri hull can out run me and burns 1/2 the gas.
