First of all I agree with most of what has been said here, but the exhaust cover consist of a stainless baffle plate that warps badly on the first overheat. When this happens it opens the cooling system for exhaust pulses to blow the water out of the water pump. At idle you may notice the pump trying to get water to powerhead, but only if the plastic tube around the driveshaft above the pump is in good shape (o-rings) and all. That is something that very seldom occurs with an overheat of this motor. The pump housing itself is prone to warp or the cup turn in the housing. When these motors overheat, lots of things have to be inspected before you get back to square one and have a good cool running motor.
