i have what i think is an 82 15hp
does the water come out of the top hole at rear
of engine and if so does it do it from the time
you crank engine or does it have a thermostat
that has to open first
thanks pops23
 
"The water will 'pulse&#39

"The water will 'pulse' out of the holes as the thermostat operates.
Thermostat is located at the bottom of the cylinder head. To get off the cover and take out the thermostat (change) You will either have to remove the rear cover latch or take off the head. Pos 19 on the attached pick is the thermostat.
I would strongly recommend to change impeller at least every second year on that model.
