Re: Just another question....

The difference between 112 & 115 is the 112 has no vro pump.

Re: Just another question....

in other words the 112 you mix your gas and oil, the 115 has the vro, that has an oil tank and a gas tank, the vro mixes the gas and oil. your gas mix is 50:1 i have a 1988 88spl on a deep v center console aluminum 850 lbs with 20 gallons of gas, runs out at 45 mph. i'd expect close to 50 mph with your set up. range depends on how you're driving, if you go to wot, and then reduce to 3/4 you will get better mileage. there is a rule of thumb, take hp, move decimal 1 place left, that gives you the average wot fuel rate per hour. 115hp equals 11.5 gallons per hour. at wide open throttle.
