So what is pretty hard? The engine use parameters for an E-rated (pleasurecraft) 6.7, which is what we assume you had, "suggest" to keep the load at 80% or less for 10 out of every 12 running hours, and wot no more than 30 minutes every 12 hours and that assumes that at wot (100% load) the engine turns above the 3,300 rated rpms. If you went beyond that suggested load, then you may have done harm to the engine; if not, it is probably just discolored paint.
