Ok, first off, I'll admit total ignorance with Evinrude/Johnson products. I have a Maxum with a dead Force 50. I bought an 85 Evinrude (which I know nothing about yet) 50hp to hopefully replace it. My original thought was "a control is a control, this US Marine thing oughta run it..." Now after reading some, I see these controls for this thing that sell for absurd amounts of money and are all "red plug" set ups... So what can I do aside from dropping hundreds into a control unit!?
