I've been out a few times lately and the weather has been very warm. The engine seems to be getting hotter than normal. I'm just not sure, It didn't do this before and I have no changes other than adding another fuel filter. The boat runs better with the air cleaner off which would point to a rich condition. The engine getting hot points to a lean condition. I don't have CHTs I just run oil temp, I didn't let it get above 200. I'm not sure whats going on, the engine doesn't smell hot of make the clinking noise like I've heard before. I do see some burning oil smoke but I have a valve cover or Oring leak on the push rod tube at the head. DO you guys running the CHTs have oil temp also? If so what is your oil temp.
