e-tech over heating??

[brianlinhard]

thinking about buying a e-tech 250hp manfuctured 10/2005 overheat alarm at 1800-2000 rpm , not at idle, or when its up and running, owner says. He said mechanic says bad sensor (its not really overheating) is this acommon problem? and I am wondering if this is a $500.00 fix or possibly higher?

Well the sensor could be bad, could also have a plugged coolant hose, may need a new water pump. It is really hard to say.
