I have two Merc's 1990 40 hp (oil injected) with bad piston (locked up) and a good running 1989 45 hp classic 50 outboard. The oil injected unit has power trim, not so with 45 hp. I wanted to pull PTT from oil injected but the swivels and bracket setups are entirely different, wondering if easier to swap powerheads if possible...thanks in advance and any suggestion grateful.

I dont know but check if the powerhead to exhaust housing/midsection gaskets are the same for both motors.
If they arent games up straight away
