I have a 2007 Yamaha 200hp Four stroke (F200TXR). I noticed water coming out of a small hole on top of the thermostat housing on the starboard side of the outboard when I had the garden hose hooked up to the engine flush hose. I am thinking that a freeze plug popped out, but I am not certain if these engines have a freeze plug in that area. Any ideas? I saw a small piece of black material around the hole.
