[QUOTE="ChopTop84, post: 1369236, member: 19210"] With t-stat stuck open, Im surprised it gets as warm as 130. Have you checked the water flow? It sounds to me like maybe his water pickup is plugged partially, or the water pump impellor is toast. Im assuming its some form of I/O boat with a volvo or mercruiser outdrive? Depending on the boat, the impellor could be in the outdrive housing, or it could be a raw water pump on the front of the engine. Either way, the rubber impellors are usually only good for a couple years before needing to be changed. If they disintegrate, they can plug up small water passages with bits of rubber paddle, and then you need to try and reverse flush the system with a garden hose or something. I would also look for a vacuum leak. Its possible he's running lean, and thats why the high temps too. Then vapor locking the fuel lines or something. I wouldnt trust the boat out on the water alone, but I wouldnt jump to yarding the motor out until I had some more info as to whats actually wrong first. [/QUOTE]
