My plane has a single-airplane STC for the -A1A and -A2B.
I would swear I've read that the -A2B is what the factory uses on the current production 150hp planes, and that all you need is the factory installation drawing (no STC required).

Added trivia:
I have learned that the -A2B is a narrow deck engine, and as such produces 150hp at 2700rpm, rather than the more common wide deck which produces 150hp at 2500.

I am with Aft. If it is on the type cert, it is a logbook entry. The new aircraft are coming with 160 hp - in my opinion a far superior engine to either the 150 or 180 Lycs. Wish my Super Dec had the 160.

Bartman, under the TCDS I see the B2B, 160hp but not the A2B, 150hp. I am in the process of doing this and checked with Ho Aviation and he is asking $1395 for the STC.

I think the 7GCAA comes from the factory with 160 hp. Without checking, I would say that the 160 Lyc is indded on that type cert.
