Here in Southeast Pa. I frequently either buy or trade them. Personally I have about 20 various sized Chrysler and Force engines.
A lot of people are wary of these engines and they are usually too big to just throw in a car so buyers usually either take them in a truck or have us mount them on the boat.
For an engine in very clean condition WITH power tilt/trim and controls I usually ask 1500 OBO but again, I may usually settle for 1000. It really depends upon what I paid initially and how much work and parts I needed to put into it. However: I offer a test ride on the river in addition to starting on muffs to show that the engine really is in good running condition.
Smaller outboards sell faster and are easier to get rid of. We prefer sizes around 9.9 to 25 HP. Because of the lake restrictions, 9.9 engines sell at a premium.
An engine that size without power tilt is a bit of a chore to raise and lower, and trailer without power tilt, price goes down to 600 or so. In any case, do it as a hobby, don't expect to retire off earnings. And remember: anything goes wrong with the engine they are going to come back. Thus you must sell with the 30-30 guarantee: 30 seconds or 30 steps. Seriously, you must make it crystal clear that the engine runs now but there is no guarantee
