Hey guys n gals, just thought I would pass on a tip to ya. I own a mid 70's 9.5 evinrude that powers my lil 14' jon boat. Well, I was having trouble keeping th motor running. After some trial and error I finally found th problem, or should I say problemS. 1st, th threads that the gas cap screws onto were pushed in a little and had a dent in it or a lil crimp which was causing air to get in and not get proper suction. 2nd, th evinrude male and female connectors that connect th line to th tank suck. Dont use evinrude for this, even new they dont work. I found that using Mercury fittings here is your best bet. Now my lil jon just flat SCOOTS across th lake, now I am workin on fixing leaky rivets. I learned about this lil tip from a local old timer, didnt get his name. So I figured I would do th same and pass it on to y'all, so in case anyone encounters this problem you can try it and see if it works for you.
