JimS123:
If you poll the marinas in my area they will try and sell you a new boat and a new motor too!!
Getting a boat/motor dealer to reasonably work on ANY antique outboard (or inboard) is almost impossible in my neck-of-the-woods.
Flat-rating the hours is beyond so many of their efforts , and it has not been a good year for them to keep senior skilled mechanics in these tough "boating" economic times. They just don't seem to want to enthusiastically work on any "old" motor.
Classic Boat clubs, and the clubs with old Antique Outboard guys seem to be the nearest source of mechanical reference for me. I am stuck doing most all my own motor work, with help from some friends of course. I don't have a mechanic.
I do have Mercs, Scott-Atwater's, my dads favorite motor was a 56' Gale Buccaneer, heck even have an old Johnson HD series, an Elto, and an Elgin (yeah, most are hanging on the walls of my barroom).
Now you have a very fine boat and motor, worthy of all the praise and affection (and awards!) given to it. You have a beautiful boat and motor. I truly envy that woodwork!
BUT, the basis of my reply is the OP's original question: "Looking for old Mercs".
My old 1959 boat carries the original Merc. My boat has never been to a show, and although it's 99.99% original, ....well it shows some age. And it has worn its Mercury on its back for the last 1/2 Century ... well since it was new.
And yep, they are definitely not for the "everyday home mechanic"! They do often need a skilled hand , and a bit of a foul-mouth too.

I stick to my contention, if OP wants a Kiekhaefer Mercury, he should pursue what he wants. If he isn't too particular, heck yes, those Johnson-Evinrudes have their virtues... (I say that with all due respect!).
