During my annual I have discovered a crack in the upper right (passenger side) engine mount. It runs from the front top near the weld almost half way to the back. There are 140 hours on the engine and all other mounts appear OK. Tim Shankland ________________________________ Message 2 _____________________________________ Time: 03:01:38 PM PST US From: "Larry McFarland" Subject: RE: Stratus-List: Stratus engine mount Hi Tim, The crack you mention is very common with that specific engine mount adapter. I replaced mine much earlier. The fault lies with the length of the gusset and the welder's failure to do a full weld around The end of the gusset. The crack mostly begins at the end of the gusset where the stress is highest and the abrupt end of the weld causes the beginning of a crack. Some have welded a strap across the crack like a bridge after welding the crack back together and that often seems to work . I built a new adapter which has a longer gusset and it's been fine so far. If you mention this to Mykal at Stratus, he'll send you a replacement.

Do you know do the replacements have any of the changes you mentioned. Tim Larry McFarland wrote: > Hi Tim, > > The crack you mention is very common with that specific engine mount > adapter.

Check for intermittent wiring connection, bad ground. Can you install another sensor and gauge somewhere? Not cheap or easy, but neither is a new engine or airplane. Do you have other temp gauges (oil, cyl, etc)?
