Post some pictures of the engine, you just installed power trim/tilt, correct? Is the gearcase in good physical condition, no leaks/cracks/bent/broken skeg? Is it a fresh water engine? Like Dan says, a "used powerhead" will be just that, nothing like a freshly rebuilt powerhead to make that rig scream the way it should.
The other option to consider is just swapping the powerhead from the older non power trim engine to the newer blown engine with power trim. The only issue may be different shift linkage on the powerhead depending on the older engine’s year/vintage.
