now, just a heads up. I don't know if you have the newer mount or the old one that is 95 vintage. but the newer mounts have a thicker wall. the old mounts use to break all the time. I had one, I changed it over when I put in my new 912uls.

The new engine is an 80 HP Rotax just like the old one. The mount is the new style. I think your right about the water pump cover. I'll look into it.
Steve,
You mentioned the older mounts breaking.. where did the breaks occur?
I am reasonably sure I have an older mount in spite of the later date of original licensing of the airframe my engine came from.

pretty close to the tank, if you have the model 4. I'm trying to place it. usually having a wedge welded in the area helped, but that even broke on mine. nice to have a new motor mount. sorry I just can't picture it. I'll look and see if I had a picture of the old mount in my stuff.

this is where the crack is, see the pieces that are welded on. that's for support, it cracks there. right in front of the tank. there is two spots.

Steve,
Thanks. I will be watching the mount closely and will watch that part of the mount specifically. Glad to have light gray paint since a crack should show as a black line.
These bits of information are a valuable resource, a clear benefit of this forum. Thanks to all who contribute. I have made many changes and decisions based on the discussions.

what happened to me was I went to a flyin, richland wa. I had the tube break right off right where those supports are. The people in the shop next to the fbo went and welded the motormount for me so I could get back home. That held up until years later when I put my new engine in, of course I went to the 912uls from the 912ul and I didn't want that bigger engine on the old mount so I had John M. send a new mount with my new engine. So Happy with the new engine and the engine mount. love my fox.
The new motor mount has a thicker wall on the tubing. well worth it.

The tube cracking on the older engine mount might look like cracked paint, but a small magnifying glass will reveal metal flakes from the broken pieces chafing under vibration. Just put the new mount on if you experience that. Its a quick safe fix.
Ok, the elbow was 180 degrees off what I needed, the fix was easy. those hex bolts are 90 inch lb torque and an easy R/R. I didn't replace the o ring in there as it was not flat anyplace and has never been used except for the test run at the factory.
today is water hose, reservoir move day.
