(gary) ________________________________ Message 1 _____________________________________ Time: 04:46:45 PM PST US From: LarryMcFarland Subject: Stratus-List: 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.

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.

From: "Hinde, Frank George (Corvallis)" 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! -----Original Message----- From: owner-stratus-list-server@matronics.com [mailto:owner-stratus-list-server@matronics.com] On Behalf Of LarryMcFarland Sent: Wednesday, September 05, 2007 4:46 PM Subject: Stratus-List: 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.
