"I have a 1993 johnson 150hp outboard, and my mechanic just disconnected the cutout switch. The reason,he did this was because when i was out on the water, the boat would cut off by itself and then would either stay off or the rpms would go back up to what ever I was doing at the time. Is this part hard to change, and what might I expect to pay for this part? is it possible to change it myself? Can do some mechanic work my self."

That means he disconnected the

That means he disconnected the stop-circuit at the power-pack.
Then remains to find out if it was the emergency switch or ign switch that created the problem.
Is Your safety laynayard hooked onto the ign switch or on a seperate cut-out switch?
