It was a P210R at FL250 and I was throttled back a little to keep the cylinders on the new engine at a reasonable temp.
The crossing was a good challenge, but getting all of the logistics worked out for the crossing took a lot of time. The CAA inspectors in Moncton said I was the last guy that was going to be required to stop in for the waiver since GPS was becoming so widely used instead of old fashioned DR. That's my claim to fame, I guess.
The shop that installed the engine wanted me to go right out for the crossing while still on the original mineral oil without so much as an hour in the circuit. A quick call to the new owner convinced them that the engine needed at least ten hours and the first oil change before the crossing. (I think we actually put about 20 on it...)
