I just recently had a simialr problem. No speed control and motor only ran at 100. I talked to the minn kota tech rep and sent him my control board and he said it had a bad potentiometer...however, I had to buy a control board to fix the problem ($215). Hate to say it but sounds like you may need a new control board.

The speed selector should be tested/check, it seems to be defective.
