I recently purchased a older Boat with a 100 H.P. Evinrude Motor. It has the old style push button electric shift on it. I pushed the center button which is suppose to be for nuetral and its still in gear. I tried pushing the forward and the reverse button to see if either of them would change anything and it still is stuck in gear. I started the motor because I heard from a friend that the motor must be turning over in order for it to change gears but that it still didnt change anything. This motor was purchased from a older man who passed away and it seems as if he was very knowledgable and his motor seems to be very well kept so I dont think it would be anything major but I could be wrong! Is there a way to check and see if the shift box is working or if the electric shift is working right? Maybe someone knows a way to check these? Also I took off the controls to see if the wires were conected and there was a wire connected to the forward button, and the nuetral button but I didn't see a wire connected under the reverse button? Any ideas or self checks that I could perform would greatly help. Thank you.
