If no one responds, maybe give Sun Tracker a call and see if they can answer.
The plastic ones i use in my 1997 Crest are: Plugs, Threaded Round, 3/8" NPT Male
Its standard pipe thread 3/8" plug. I suspect your problem is you broke the plastic one original to that boat, right? (they are bad to do that) what happens is some of the original plastic plug is still inside the toon, that prevents the new one to go in. the simplest solution is take a torch and melt the original, (careful of any wires or cables) and insert the new plug.
