Pictures of thermostat.. unit seems basically clean.
The purple springs appear to be some sort of safety release in case the water pressure exceeds 1.21 jiggiawatts.
this design is less than desirable. water cannot get into the engine without the air being displaced. the thermostats have no pinholes in them whatsoever to let any water thru.
the only way I see this motor filling with water is if the air escapes, and they only place i see the air escaping is thru the one little tiny hole shown by the red arrow in the picture. the hole’s placement is an additional problem because water is much heavier than air, so if any water did make it’s way down to the this hole in the thermostat, then it would leave before the air. (since this little hole is at the lowest level).
to me this design spells Engine failure by overheating as I don’t see how the motor could properly consistently fill with water.
perhaps there’s some fancy passageways going on inside the motor to compensate for this problem?
I created a quick picture of how physics would dictate water flow of a generic omc engine.. but since these omc motors tend to run and not self destruct, there must be more to the story..
