100 hours seems way too short. What do the bolts have on them? (Regular nuts, with or without split/lock washers and flat washers, Nylocs, Loctite ?)
My orignal Amel installarion had bolts with a small diameter L shaped rod welded to each bolt head, that went into the adjacent (extra) hole on the Vetus dampner housing and that prevented rotation when tightening the nuts - very handy. It then used flat washers and lock washers on the nut end and a conventional nut (not nylock). They never loosened.
Over the years I've switched to just nylocs and have had no loosening now for the 500 hours since I last pulled the engine, at which time it was still tight from the engine pull before that.

I just tightened all four bolts...they had loosened slightly over the last couple of months, not even 100 hrs of motoring since the last tightening session.
