I bought a long block 350 Chev marine motor for my boat. I bought the long block because it came with a 2 year warranty. After install the motor continued to push coolant and pressurize, overflowing out of my heat ex-changer. I paid the company that did the install to replace the heat exchanger, check all kinds of potential issues. Only to find out that the head gasket was blown on a brand new motor. We sent the invoice to S&J to have them cover only a small part of the repairs and they refused. Brand new motor with not even an hour on it.
