Question on thermostats,
Removed the thermostat last fall to winterized the boat and now can't figure out if it goes on the intake manifold or between the thermostat housing? It's a 2 piece housing with 3 bolts vortec sticker on the top.lower section has the water intake hoses and top section has the hoses to exhaust manifolds
Both spots has a notch for a thermostat
It's a 2004 moomba with a indmar vortec 350
Any help would be Appreciated

Usually between manifold and housing (on the manifold). Can you see a little recess ring on the manifold for it to sit in?

Yes there is a re
ssessed rim on the manifold but the upper triangle piece also has one to?

I want to say that the spacer/splitter is for better hose clearance and angles. Most automotive applications have the thermo right in the manifold.
