I did a search for this and didn't find anything. I have a single side mount throttle control on my '91 Prowler. How do I get inside to check the throttle/shift connections? There are 2 screws on the ouside panel and 2 screws on the inside of the throttle control arm. One you can get to, the other you can't. The only other thing I can think of is the neutral lock-out button, but all it does is turn. I do not know what brand of throttle control it is, but it does look something like the Morse SI here on iboats, except it has chrome trim down the middle of the arm. blt
