Thanks for the responses I will get some pictures as soon as I can. Also the serial number I gave was on the engine not the hull, all of the other numbers from the hull are faded off of the plate and unreadable. I ordered a new shift cable today and the cable I brought in was from a '72 to a '78 out drive, I am kinda thinking it is around a '72. If it were a '72 20' in good condition could somebody tell me what it would possibly be worth? I got the boat for free and am not planning on selling it, just asking so I can insure it without under insuring it.
