View Full Version : 1962 CHRIS CRAFT OVERHEATING
09-09-2003, 12:24 PM
" I have 1962 30' Chris Craft with twin 283 engines. The left bank of my port engine is overheating. I have replaced the impellers and checked for blockage but have not been able to locate any. According to my Chris Craft manual there is no thermostats in this engine, is this true. What else can the problem be or have I overlooked a possible water blockage point. It does seem like there is an obstruction. "

"Mike, it was very common for CC 283's of that vintage to not have thermostats. If these are flywheel forward engines, your water pump is probably a dual impeller Sherwood or Jabsco model and has hoses going into the exhaust manifold inlets on each side of the engine.
How have you determined that the left bank is overheating? If you have checked for good flow at each hose, and water is flowing unrestricted from the top outlet of the left head, then the blockage must be downstream.
It's also possible that you have enough crud accumulated in the block water jackets to restrict flow.
