My 1979 Aquasport Open Fisherman is missing the throttle neutral button. It is the original controls from the factory and has the original Mercury 115. Does anyone have any idea if a parts schematic exists and where a replacement button can be found. My index finger is getting tired of pushing the pin in without the plastic button. :)Thanks for the help!
I think I found the neutral button. It appears to be a Quicksilver remote control assembly and the button part number 74326 (#49) is shown at the link below. I found the original accessory guide that came with the boat and there was an exact match and assembly part number (74578A 2) in the guide. I will give it a try and let you know how it works out. Thanks for everyone's input.Control Parts from dougrussell.com
