Paul,
I'm just starting the disassembly / inspection of my 20B for the purpose
of an aircraft conversion.  The thing that seems to be worrying me the
most is the water pump.  That thing is huge, or at least it sticks up in
the air a mile over the top of the engine block.  And....the pump is
cast iron in an aluminum housing....very heavy!!  Is there some way
to modify, or preferably another pump that will mount in its place that
will solve these issues?  This thing will NEVER go inside the engine cowl?

Thanks again!!
Don Mitchell


--------------------
I don't know what year/model the pump is; but this is the front of my 20B
(see photo).  It is a 12A front cover, and the low profile pump exit neck
is; I think; from a 1986 13B.  I went to the Mazda dealer and looked through
the parts book for the lowest profile outlet.

(Good thing the engine is still of the airplane so I could get this shot.
Tension bolt torqued.)

That is a 13B  2nd gen water pump with a seven bolt cartridge as far
as I can tell Al. In 89 Mazda went to a 8 bolt cartridge.
See the attached second jpg. You sure have a lot of different parts
in your 3 rotor :)
