Here we have a John Deere PowerTech 13.5 diesel marine engine with only about one years of use and 1200 original hours. It was in use in a tug boat and sustained a minor rear main seal leak, the transmission was attempted to be pulled to replace the seal while the rookie left a couple of bolts still attached which resulted in the lower portion of the bellhousing cracking. It is not into any water jackets or oil area so could easily be welded but does need to be fixed, we do have a competent local shop which can do it if youd like for $1000, or you can use your own guy. Email if you have any questions.
