is there one of carb
See the 2nd pic from fifty2One above for pics of carb. Under “M-20 Fuel System”.
Ignition points are “out there” Often the contacts can be polished to a mirror finish (or at least acceptable finish) and give good service for as
long as an antique might see use.Water pump kit may be a harder item to find. A lot of time we have to
improvise or wing it. In the 21st Century finding New Old Stock parts
for an outboard made in the 1st half of the 20th Century is not always
the way to go, There are several vendors of used parts and there are
options available to clever native craftsmen with time and patience ,
A general response, I could refine it with a little more specific
question. There are 3 different water pumps, each will work as an
assembly on any pre war or early post war outboards made by
Kiekhaefer Mercury. Some post factory swaps or upgrades may
have taken place. Mercury did offer a kit to upgrade to the later
vane type water pump….merely the same pump as used on the
later motors, A no brain swap.

Kiekhaefer Mercury evolved thru 3 part identification systemsprewar: an illustration of parts with a number and a sequentiasl number
list as part of owners manualpostwar better quality illustrations and an “M” prefix, The introduction
of KE7 and KF5 complicated mattersCurrent parts system was adopted in early 1950s. Most parts are
identified by 2 digit prefix to identify part type followed by 5 digit
part number and an “A” plus a number indicating more detail
At the time the new system was adopted a New Parts List for Mercury
Models manufactured 1939 to 1953 was issued. This converted the
old parts systems to the new systemOK so far?
Kit, Water Pump Conversion Part # 46 – 24424 A4 is the new
system part number A4 indicates 4 components in the kit besides
the water pump housing. Parts name and number as follows46 – 24424 A1 Housing Assembly
26 – 22058 Seal, Oil
47 – 24447 Impeller Assembly
24430 Hub. Impeller Drive
24429 Cover, Water PumpThe inclusion of a cover is probably because aluminum used for
earlier water pump covers wore and corroded. Revised covers were
made of brass and had a slot instead of a hole to engage locating pin
in water pump housing.Hope this is helpful. AND is the answer for question you posed.
If you are converting from an oscillator type pump to a vane type pump
photo shows parts needed along with carry over parts from the
earlier type pump.1 user thanked author for this post.
