TOPIC: Barn find Mercs. Worth?

I have two. First is a Mark 55E. Turns over good compression. I have the control box, cables are toast. The lower unit is cracked where the prop shaft cover nut threads are. Was told that water in the lower unit froze and cracked it. My welder says he can fix it...
Second is a 300. Don't know the year, it's white and the wraparound cover is black. It turns over, good compression, the lower unit shifts. I have the wiring harness.
I'd like to get an approximate value on these. I will have them for sale at the AOMCI Swap Meet in Rocky Hill CT this weekend, 3/23.
TIA

LARRY, CONGRTAS , good find. LARRY here in East Tenn, Prior
lower New York state AOMCI ,. Cosmetics & face plates would
be the real value issue, since you did not post any pics.
White 300 should be close to 61 (?) Maybe a 14' boat would
be your customer..A quick guess would be $250 on the 55 &
$200 onthe 300 .. Multiple PROPS.?? usable cond. ? Bronze.
LINK below states 300 only in 1960 rated 35hp. The 350 for
61 was 40 hp . Then back to 63 the 350 droped to 35 hp .??

.. Take some pics at the meet.... Here is a MICH LINK one of our
members put in SIGHTINGS a few days ago. Your 55E should look
like the motor on the LEFT ?? in the pic.. If you got these heavy
Dealers stands from "K" ,now we are talking some value.
