I've got a vintage Morse side mount thottle/shifter on my 1972 boat. It worked flawlessly until just recently when I had new seats and side panels installed in the boat. They had to unmount the throttle from the side panel and then re-install it once the side panel was ready to go. I asked them to move the throttle up a couple inches so it would be higher and more convenient. So, they did that and I took the boat and found out there was something wrong because I could not get any gas to the engine. So, I took the boat back and they found that something on the back side of the shifter was 90 degrees off from where it was supposed to be. Before taking the boat out again, I ran the engine on the trailer to verify that the shifter was working OK -- it seemed fine, although I had a hard time getting the neutal lock button engaged (by angaged, I mean pulled out). Took the boat out and the thottle worked fine for forward and reverse and straight up neutral, however it is very difficult to pull the neutal lock switch out so that you can proivde more throttle in neutral. For fear of going into either forward or reverse while the engine was running and trying to get the neutral lock button pulled out, I would just shut the engine off and then work the throttle/shifter back and forth in the area right around neutral...eventually I could get the lock button to pull out.
Does anyone have any ideas on what may be causing this issue with it being so difficult to enage the neutral lock button?
My throttle/shifter is just like this one:
