Hey Everbody,
I have a very nice 1988 Sundowner 205- 4.3 ltr chev with cobra outdrive.
Underneath the aft swim platform is a big (approx 1 ft diamete)r white plastic disc with a screw off manhole cover that has an O-ring seal in it. When you open it up, all I see is the substrate of the swim platform and the glas coating underneath it. What is this thing and how should I be using it ...if at all? Am I suppose to open that up to keep back transom area dry after use? I don't get it.
Thanks for any and all responses
Jim
