Hard to beat a deal like that Wannabe! Yes, 3/4 pt. to a gallon of fuel, but I regularly run my "75" at about 24:1 with synthetic blend. The lower unit uses #40 wt. oil because of the Twist Shift. Others without the shift use grease. One thing you’ll want to check though is the water pump. Because of the twist shift it uses an impeller type (available from Russ) instead of the "wobbler" type in "60’s". It’s not tough to drop the lower unit though because the access plate on the side of the leg gives you access to the spring clip that links the shift cable to the lower unit. But those little vanes are prone to break off with age. (And once you’ve replaced the impeller on a "75" it’s the same process for a "100".) Enjoy!
