More manifold pressure makes more power which wears the engine out faster.
It is instructive to note that Rotax decided to limit 35inches to five minutes. This suggests to me that during some tests they found what they considered excess wear with too much boots for too long.
Vance correct me if I'm wrong but I was sure the 914 was max boost of 39" for 5 mins?
Edit; I went looking and found the answer myself and I was right, they are 39" some may get close to 40" for the full 5 mins, then the max 100% boost is actually 36"
