Does my engine have a Poppet Valve?

Question

I have a 95 Johnson V4 130 HP. I posted a earlier question about it over heating and i was wondering if it has poppet valves and where are they?

Answer 1

two, one in each thermostat housing

Okay, they don't actually call them "poppet valves" -- the thermostat is held down by a spring.  when pressure gets high enough it lifts the 'stat off its seat.

Call it a "high-pressure bypass" or a "pressure relief" if you will.  

Same function.

Answer 2

The best way to answer your question is to buy a clymer manual for that engine.  If I remember right they are at the bottom of the cylinder heads.  It has been a while but I dont think they are even by the thermostats, it doesnt make sense since they are put in to even out temperatures throughout the cylinder heads.
