clams.. my 86 or close 115 inline 6 ..got funny on me the last of the season...sometimes i would lose fuel gauge ,if i cut it off i had nothing...no tilt no crank...if i left it running no gauge...no tilt ...but running...my buddy had a 200 merc he said it was a solenoid on the starboard side...it is very intermittent...the boat is in my garage and i check every coupla' days...still goes up, still got gauge...don't dare crank.plenty of time as boating don't start in maine till' ice out..may is usually good!!!
