My 35 hp Evinrude worked fine a week ago. It won't start this week. When I turn the key I can hear a clicking sound but nothing is turning. I have recharged the battery to 100% and changed spark plug. Still nothing is turing. At the end of the last run, I felt the motor lost its power partly due to (maybe) too much additive in the gas tank ( I did not add 2 cycle oil to 50:1 ratio perfectly). <br />The fishing season is ending in MN soon so please help me out.<br /><br />Thank you very much.<br />Mike
