Thermostat and plastic sleeve for the thermostat were missing. Bolts that should be in the kit that mount the thermostat to the head were substituted for bolts that that don't fit anything on a Mercruiser 3.0...I know because I know every nut and bolt on this engine. They are so big they won't even fit through the holes of the thermostat housing, let alone anything else. Plus the bolts that were provided are cheap carbon steel. Ok for fresh water, completely useless for salt. Moral of the story: don't buy this stuff online unless it's genuine Mercruiser or Quicksilver. All of these boat part websites are selling the same junk. The sad thing is, I bought an exhaust elbow from iboats.com on this same order and it came with more parts than expected plus the bolts were stainless steel. Go figure.
