Where can I purchase a thermostat housing for a Marine Power 454 engine built in 1998 and installed in a Luhrs? Are there are few good sources for parts for Marine Power engines?

Need more info.
Is this for an open system (aka raw water cooled) or for a Closed Cooling system?
The two housing are quite different from one another.

It is for a closed system with a heat exchanger.

If this is a single outlet housing, it may be similar to the auto version.
Can you post an image of the old one?

It is not like any auto version that I have seen. Note the 2 3/4" hose connections and the single 1/2" hose connection.

The 3/4" barbs are likely for the hoses going to the manifolds....where does the 1/2" hose go?

Partman.com contacted Marine Power and special ordered me the part. Based upon my multiple phone calls and contacts with Partman.com I would highly recommend them.
