I just bought my first boat for very cheap its a 1971 starcraft with a 60 hp evinrude triumph motor. I tried to get it started today but when I turned the key the starter turned over and I kept trying but no start so I got frusterated and left and came back and when I turned the key it wouldn't even turn but I know for a fact the starter works we used two wires and a battery to see if it would work i dont understand it makes no sound now but did before when I turned the key?? any ideas
