The drive shaft seal on all models K1 thru KE3 and WA2 thru WG4
as well as the two Sea King singles is a piece of leather or raw hide.
Replacement can be using gasket punch. I can not recall ever finding
an old seal that was not rotted or missing entirely.
Drive shaft is ground on gear case end and is slightly smaller in diameter. If the larger end fits thru the bushing in gear case , the bushing is worn out. Both bushings in the gear are cast into the gear
case and can not be driven out. Boring out busing and pressing
in inserts and reaming would require a holding fixture so
the two bushings are in precise alignment.,,a lot of work for just one
gear case, Easy solution is good usable gear case from any og
the many models that shared gear case.
There were 3 different water pump designs, each will work with any of
the Early K Models and their Wizard and Sea King singles made by
Kiekhaefer. The propeller shaft, water pump cover and the retaining
spring will work with all, The rotating impeller design (3 slit water pump) are preferred as the oscillators are hard to come by. The
16 square hole and 7 slit water pumps are more complex and often
are missing small items.
The single cylinder models have a 12 tooth pinion on drive shaft and a 22 tooth gear on prop shaft. No shims or spacers.
The twins have 14 tooth pinion on drive shaft and an 19 tooth gear
on propeller shaft. PLUS two 0,010 steel shims on propeller shaft
ahead of the gear AND a 0.100″ bronze spacer above pinion gear
and a 0,010″ steel shim between spacer and bushing,
The steel shims are often rusted or missing along with the bronze
spacer. These parts are essential for proper gear spacing and smooth
operation. The gears will self destruct without the spacer and shims
properly installed.
Also note the 12/22 and 14/19 are gear sets…they are NOT be mixed.
Sometimes you find a twin with a single gear set or a single with
a twin gear set due to prior work. May overheat overcool due to water
pump being driven too slow or too fast.
Drive shafts often have worn splines or are pitted in area of seal and
bushing…drive shaft lengths vary so best to compare old and potential
replacement before purchase or assembly.
The seal in 3 slit rotax rotating impeller type water pump have a difficult
to remove seal that is usually well past its Best By Date. Replacement
is a standard inexpensive item, but, first you have to get the old seal
out which may involve removing it a piece at a time.
The early K Model Kiekhaefer outboards are well though out designs
but, they can have wear, corrosion and lost parts issues. Fortunately there are a wide range of years and models sharing the same or will fit
parts. Unfortunately cowls and spark plug covers are usually gone and
the available supply is thin, Complete and original examples are worth
a premium just to avoid a parts chase. Even a bare bones parts can be
made into runners that may someday find the rest of its partsl

Twin Gear Sets are 14/19 I stand corrected.
