Ok if it was ZCR then it was a B200 not a B300. Even at MTOW the B200 would perform very well OEI. No problems meeting the climb gradients required using SL ISA. Not sure of the conditions during the departure but my assumption is that they would not have been too extreme and therefore I would contend that the B200 would have no trouble climbing out OEI in those conditions.
A B300 would do even better.
Both have autofeather systems and rudder boost, all to reduce pilot workload.
