If your Marathon has a pot-box type throttle, disconnect the two wires
What happens is that a microswitch on the F/R places a 5K fixed resistor in parallel with the 0-5K pot, so the controller only sees 0-2.5K rather than the normal 0-5K.

Thank you for the explanation regarding the pot box. Just what I wanted!
I did return the S1 and S2 to their original positions so I will leave the A1 and A2 alone. I will disconnect the 2 wires between the pot-box and the F/R assembly to get rid of the 1/2 reverse speed to simplify matters. Evidently the micro is defective?
I'm really not interested in 1/2 speed!
Thanks again for the explanation,
Dennis
