1979 V20 I/O Questions

[cmk245]

I recently joined the Community, and acquired, a 1979 V20 with 470 Merc I/O.
1st. group, of many questions as I go about checking out the boat,

Looks ALOT like a my old (76) 19.6 Aquasport Family Fisherman that I had.

1) There a 2- lift up doors on either side on the rear Transom. PO had "Plywood Boxes" on both sides that drained to nowhere.....(fill with rain water)
.
Were these Fiberglass at one time and maybe replaced?
where did they drain to? I had a searay that had ones that had thru hulls to drain out sides of boat above waterline.

2) where do the deck drains on either side of motor box drain to?
looks like just into bilge?

3) Does anyone have a link to copy of floor plan the this boat? and specs. would be appreciated,too

Wellcraft is unless, since they sold business, as many wellcraft dealers that I knew about are now selling something else.......

And many V20 photos I find have Outboards on them.....
