I am currently looking to purchase a used boat with twin 84 115hp OMC Sea Drives. One engine was rebuilt and has 50hrs and the other has 130hrs. I have previously only owned boats with Merc I/Os and am not familiar with this motors. I have read that they are no longer made. Is that due to design problems? Are they in general a reliable power option? Are parts available? Should I run away? If some one could give me the skinny on these engines I would be very grateful.
