Ok, hi to all! I have a 1991 Carver 430 cockpit motor yacht. It is my intent to crawl through and into every space that I can to better know what is what and how to properly maintain it. I discovered a cap on the starboard aft under the exhaust outlet. I unscrewed the cap and there is this bolt/screw that I have no idea what it is or what it does.
Nothing in the manuals, drawing or on the Carver website.
Any help greatly appreciated.
Tom
