I have a question about the thermostat and housing on a 1978 OMC 185 (chevy 305... Thanks fone_man) I replaced the intake and carb this weekend and i noticed that there was no thermostat in the normal location on the manifold. What was there is a much larger housing that has the one large water intake hose, 2 smaller water hoses that go to the exhaust manifolds and one other that goes to the outdrive (not sure on this last ones destination.) There is what appears to be a thermostat between the main large hose location and the 2 exhaust ones on top. However this is molded in and is not replaceable. Also, the 2 ports on top that go to the exhaust manifolds have small 3/8" outlets, about 1/4 the total size of the hose that attaches. <br />One more piece of info. The temp hardly every rises above 120. after 30 min at WOT the temp will reach 140...<br /><br />Two basic questions...<br />1. Is the thermostat just missing??<br />2. It was dificult to tell if the exhaust water ports to small due to build up or if they are intentionally small. Should they be so much smaller then the hose?
