Good job Jake handling your cooling problems. I am sure you will work it out. My friend has a Avid with 582 (project) that may have to deal with the same problems. I am still on the ground after a fuel pump forced off field landing 2 weeks ago with my Quicksilver MX - Rotax 447. No damage, I didn't push and try to cross the cattails to return to my grass strip but 7 hour recovery across cattail swamp. We have had the last couple weeks of no flying with dense smoke and ash fall from forest fires 80 miles away. Another friend has a 582 powered plane I fly, it goes to and stays nicely at 170F.
I've never ran a 583, but had 582s in three Avids. I'm not sure why you feel the need to run it for so long on the ground and get it real hot before you ever take off. Isn't 130 or so minimum temp for full throttle operation? Some times it helps to lower the radiator about an inch so it catches more air flow as well. Looks like removing the bottom piece of the cowl helped some. Was wondering if you were going to fly again to see if temps stayed in line after that. Air flow at flying speeds will cool much better than just the prop blast when it's sitting on the ground. With the 582, max temp was only 180 and as I understand it, it's because of the plastic bearing cages used in the engine. Wonder if the 583 uses the same type. Interestingly, the 532 had a higher allowable temp, but it didn't use those plastic bearing cages. Keep up the videos, have fun and fly safe! Jim
@@jimchuk8511 the limitations in the Avid and Rotax manuals we have with our plane 200° F max water temp. When we did the motor I don’t remember any plastic or teflon type bearings. When I did the engine break in it never overheated. It started overheating when we put the cowlings on. I flew two very short flights with the cowlings on and unmodified and it shoots up to and beyond 200° in a hurry. After trimming the air dam on that lower cowl, cooling problems seem to be solved. This engine is maintaining 180° much more consistently than the 582 did. So far. I flew it 1.1 yesterday with about 10 cycles and no temp problems, except one full power run up. Why full power run-up’s? Just the idea of cold seizures. Frankly, Rotax Rick recommends it to assure all the moving bits are at their operating temps. Not saying I prescribe to that doctrine but I must at least to some degree. A new video for yesterday’s flying is forthcoming. I plan to leave the pattern tomorrow and fly 50 miles out or so. 🤞

Enjoining the videos. Thanks for posting.
You could always run an inline thermostat to help balance out the temps.
I think there may be some aerodynamic restriction in the engine airflow. The videos are very good!!!
