jemill17 0 Report post Posted April 15, 2012 My marina does not carry the adapter for the waste fill. Can anyone tell me what type of adapter I need for my 1999 Monterey 242. I was told that there are three types based on thread size, but I do not know what thread size was installed in the boat. Everything is factory, so it should be somewhat standard? Any help would be appreciated. Thanks Share this post Link to post Share on other sites

I had to do the same thing when we had our 282. Marina pump out did not fit, so another gas dock had the correct one, and I got part #'s and measurements off that one and bought one. Can't remember the exact size now though. Share this post Link to post Share on other sites
