| Subject: | water pump anyone? |
Hi Guys,
I decided to buy a water pump for the Stratus Subaru EA-81 as these tend
to fail with some warning, but on their own schedule. So it seemed
prudent to have spare parts, belts, plugs, filters, etc. The EA-81 has
been a great performer with exceptional economy. I ordered a water pump
for $26.00 at my local auto parts store. For the car data, it turned out
not to be the correct one. The pulley (which was not included) was to be
fastened with 4 bolts (not included) and the later than 1984 design
pressed steel impeller is reported to self-destruct at high rpm. I
visited *OReillys auto parts web site and found that the part number
for the correct pump is* *57-1042*. This pump has the preferred cast
impeller, the correct mushroom shaped pulley (attached) and it is listed
for $26.99 less $3.00 core-exchange if you happen to need one.
Data used for both was *Brat 1.8 pickup truck 1982-1987*.
Another source part number for it is 53105, GMB water pump.
Both are built by Cardone Industries.
Stratus only provides Atsugi as "Specification" for the pump which is
interpreted to mean it has "its own" characteristics.
No one flies 100 horsepower pound for pound as inexpensively as the
Subaru EA-81.
Tuck this info into your Stratus manual or reference information and
avoid the 48 hours of bewilderment.
Happy flying guys,

This was probably just a fluke but I bought a pump making sure it
had the right impeller and all. A year later when I put it on I
noticed the belts did not line up very well. I measured the old
and new pumps distance between the mounting gasket face and the
center of the pulley and there was a 3/16 of an inch difference.
It was too late to take it back so I had to buy another and it
was fine. May be good to measure before you cant take it back
since you may be keeping it on your spare parts shelf for a while.

Oh don't you just love a naysayer...but here goes..:)
Your last statement about the economy. I don't think you can really say
that Larry until you know how long Stratus lasts.
I mean if you get 2500 hours like you will from a 100HP airplane motor
then yes maybe your right...But do we know this yet?
Secondly, if your simply comparing fuel costs then airplane motors (at
least fuel injected ones) can be run more economically than the Stratus
simply because you can run the engine lean or peak exhaust as
temperature.
My 190Hp IO360 will normally run 10GPH but that can be got doen to 7gph
running on the lean side of peak EGT...this has a significant effect on
fuel caosts and as almost all airplane motors can be run on auto fuel
then the comparison could be a lot closer than you might think.
Sure the airplane motors cost a lot more new but if it lasts 3 times as
long how do the numers stack up then?
On the whole though, with sorted valve guides, the Stratus setup is a
sweet little motor.
All the best
Frank
601HDS 400 hours
RV7a IO360 21o hours in one year...YIKES!
