   Jeff,
    You might keep an eye on the plastic hose goinng to the bottom of your
expansion tank..........This particular hose is not durable and under the high
heat under the cowl (perhaps not during your Canadian winter) might have
a short service life..........Project looks great and am looking forward to all
further flight test info..........

Thanks to you all for the congratulatory comments … attached is a picture of expansion tank and preflight roll-out … the orange line is fuel return; the brass is pressure gauge pickup and snifter valve installation.
After reading Eds’ email I now know why the water temperature was so high.  I installed a thermostat with the onset of cold weather, but I couldn’t use the original Mazda thermostat because my temperature bulb protrudes across the bypass hole.  Originally the bypass hole was plugged and there was no thermostat; however, I removed the bypass plug and used a non-Mazda thermostat !! … so that’s why the underside of the Mazda thermostat is so long! Thanks Ed for setting me straight and based on your comment about 20% loss of efficiency, I could possibly see 230F x 0.8 or as low as 184F on next flight … that would be great! For now the thermostat is gone and bypass is re-plugged.
Closer examination of the belt and rubber deposits on underside of top cowling suggests the belt got jammed in the pulley and cut by friction.
I tried again last night to remove the alternator pulley nut … what’s the secret? Left-hand thread? Loctite or what? It’s so tight I’m afraid of damaging something trying to get it off.
