I have a modele E25RETS 25hp year 1993
the water pump is not getting water to the head I suspected the thermostat so I removed it
Ran the engine with the cylinder head cover removed still no water reaching the power head
I connected the tap water up to the pump outlet pipe going to the head at just more then a water droplets water filled the hose and shot out of the tell tale hose
I want to remove the power head to see if the intake gromet is blocked and is restrecting the flow from the water pump does anybody no where I can down load a manul discribing how to remove the head
the water pump keyway is properly installed

sorry to be so long winded

 

I have just lifted the powerhead off but not removed any wires or the carbs. Just lift it high enough to clean the gasket surface.

I haven't came across any manuals online.
