Decarbed my 92 Johnson 115 CF using the seafoam method with a 1gal remote tank. After two 15min periods of running at fast idle (1400 rpm) the 1gal mixture is almost gone. Is this normal fuel consumption for this motor?
Thanks for the reply Rick. I know these motors suck a lot of fuel, but 1gal in 1/2 hr just seemed a little much. Thought it may have something to do with it being out of the water (no back pressure).
Won't know till I put it in the water Sunday. The idle increased about 100 rpms and sounds smoother. A lot of crud came out of it. I had just decarbed about 10hrs ago with the OMC stuff. The seafoam method seems to clean it out better.
