Narrative:

Local training flight for multi-engine training. Student completed normal takeoff, however, was having difficulty maintaining altitude due to power. I instructed him to level off but the climb continued. I looked at the local area and determined it was safe to maintain the current altitude in excess of 2000 ft AGL. Later, after looking at the terminal chart, I realized we may have been on the edge of the fll class C airspace. My distractions with communication, the new student's performance, and the confusion over our actual position contributed to a possible entry into class C airspace.
