I recently replaced the manifolds/risers, flapper valves, raw water impeller and the 160 degree thermostat. I went to fire it up and started perfectly. I was watching the temp gage barely move. I was still able to place my hands on the risers without getting burned, but did notice some steam (more than I normally see during the warmer air temps. I shut down and checked things out. The left side hoses coming from the thermostat housing were much cooler than the right ones. And the right riser was warmer than the left. Could there be a air pocket causing this? I pulled the thermostat to see if it was installed wrong, but I think the thermostat will only go in one way. The boat always ran at 160 indicated on the gage. any ideas or thoughts would be highly appreciated.
