The 3HM35 has a continuous rating of 3200 rpm with a 1-hour rating higher than that, so it is probably worth continuing the hunt for issues (maybe around the exhaust water injection?). A properly functioning engine should not overheat with load from a few barnacles, should it, or was it really fouled?
