I have a 91 Evinrude VE40 (I have no idea what the VE stands for). I've had problems with high end speed. I've rebuilt carbs and replaced fuel lines and filters, well, I've had it done. The only way the boat will run above an idle is to constantly squeeze the pump ball. It goes flat but if my wife is willing to sit in back of the pontoon boat and squeeze the bulb we can get off the water quick if needed. One of the things that I changed after having the second motor overhaul is we listened to a mechanic who is no longer there and started using a quart of oil to 6 gallons of gas ( I think this is 100 to one). He told me the pint I was using wasn't enough (50 to one?). 1. What is the right fuel mixture for this engine, 2. does the bulb need to stay full or am I sucking air into the lines and if so how do I check and 3. do I have a fuel pump that is not demanding enough gas????? Help.
