Well! Whaddaya know! The inner set of screws *IS* 1/4″
Got the flywheel off to find it’s the dreaded scintilla magneto.
I have spark, but the plug wire is in terrible shape.
It looks like the coil is riveted to the plate?http://www.omc-boats.org
http://www.aerocraft-boats.orgNovember 15, 2019 at 9:56 pm #187242Phil, earlier you were asking about a manual for this motor. Been looking through my stuff and don’t have one for this motor. However I do have one for a KD4 I could send you. If you look at the K model manual located here http://pub9.bravenet.com/photocenter/album.php?usernum=737212788&album=49067#bn-photocenter-1-1-737212788/49067/1/ you’ll see that many of the parts interchanged from the K1 thru the KE3. Between this document and the KD4 manual you most likely can get SOME info that will help you with your KD3.
If you’re interested PM me your email.

November 16, 2019 at 10:13 pm #187321Allow me to put my oar in…Kiekhaefer singles are pretty simple and
neither service nor parts manual are needed. If you have a nice
running example that has not been molested by the unskilled. count
your blessings. Work carefully, take notes and photos and keep
track of where each fastener came from as it has to return to same
place. Impellers, upper seals and the lower driveshaft leather seal
are almost always bad.

The outer 3 small thread holes are for attaching the stamped steel
back up rope plate for use if recoil starter fails, The inner 3
larger thread holes are used with fly wheel puller.- This reply was modified 5 years, 1 month ago by green-thumbs.
November 17, 2019 at 1:08 am #187326Hey Louis. How you doing Buddy? Haven’t seen any posts from you lately. wondering when you were going to weigh in.
KirkNovember 17, 2019 at 3:35 pm #187362I have a soft spot for down on their luck early K Model Mercurys and the Sea Kings and Wizards also made by Kiekhaefer.
From the top down…a list of problem
1) rewind starter: broken spring, gob of solidified grease, missing fasteners and a very small but vital key gone astray
2) the usual magneto problems
3) upper seal in need of replacement (7415 )
4) crankshaft bent or rusted
5) crankshaft needle bearings rusted (postwar models))
6) rod bearing corroded (postwar models)
7) pivot pin corroded stuck
8) drive shaft stuck in or crankshaft splines
9) lower driveshaft seal missing or rotted (formed from leather)
10) bushings in gear case worn out
11) corroded or worn bearing areas on driveshaft and or prop shaft
12) rubber water pump impeller defective (usually a given)
13) seal in water pump housing defective (3 slit water pump housing)
14) clutch and or prop stuck to propshaft by corrosionwear and corrosion issues with piston, cylinder ,water jackets
or a seam leak with cast aluminum gas tank are not unknown.
Problem…be patient and consider what your options and consequences.NOTE:#1 all problems have one or more solution including down grading from restoration prospect to parts motor
NOTE #2 What you see is what you get…if it looks like it spent
a decade or so out in the weather it has issues. If it looks like it
was well taken care of it may be a rare starts on first pull with fresh
fuel motor that everyone hopes for,but,seldom finds.NOTE#3 missing handle grips, cowls,spark plug covers, knobs and so on are hard to come by and/or not cheap…look over carefully to know
what is missing and probable cost of replacement before purchase.
Remove the rose tinted lenses when contemplating spending
big bucks. At a right price and for the right person, even motors with
problems can be a right buy. Not every price is right nor is everyone
a right person and a few motors are bad buys even if free.

November 17, 2019 at 6:53 pm #187365Here is what I have, some diagrams overlap? KD-3 / KD-4
I have the full size training diagrams and gave many copies
Out at Constantine this year, but can not scan due to size 20 X 18http://pub9.bravenet.com/forum/static/show.php?usernum=737212788&frmid=52&msgid=715480&cmd=show

November 23, 2019 at 4:19 pm #187912Do I need to do a full tear down??
Removed the KD3 (scintilla) coil today so I can replace the rotting sparkplug wire– It wasn’t even soldered on?!!!!
Of course one of the clips flew off (I thought it made the distinct noise of landing in a particular box, but can’t find it)!
Coil tests as 1 ohm on the primary, and 6490 on the secondary (had spark before opening it up).
The condenser measures 0.354 microFarads.
