1963 75hp Tstat Housing Repair Advice

[yorab]

I noticed that my tstat housing is broken. Specifically, one of the three "nubs" that supports the Vernatherm has broken off. I made my own support with epoxy as seen in the pics. Sorry for the blurry pics. The original nub was very small compared to my epoxy repair, but I wanted to be sure that the epoxy had some real estate to adhere to. I believe that if I made a thin support like the original, that it would have broken off and ended up downstream somewhere, posssibly blocking water flow. That is why the epoxy repair is larger.

I can see that water flow will be affected by my larger support because water can't flow behind the support. However, I don't know if the flow will be affected significantly. Does anybody have an opinion on whether the water flow will be disrupted enough to cause problems? Thanks.

I was looking at these tstat housings online. It seems that the same housing was used for quite a few years into the '70s. However, I see that the later housings (with the same part #) have barbs on the hose connections. As you can see from my pics, the hose connections on my housing are smooth. Even though I believe that my repair may work well, I may replace the housing anyway so that I can get a barbed fitting. It may do a better job of preventing leaks. I have not had any leaks from that area before, but a bit of security is always nice. Any thoughts on any of this?

I decided to buy a new tstat housing so that I could have the barbed connectors. I believe that the epoxy repair would have worked and not restricted water flow too much, but I found a good deal on a housing.

In addition to barbed connectors, I see that later tstat housings (even those with the same part number) had another change: the 3 nubs that support the Vernatherm are a bit beefier. Perhaps the engineers thought that the skinnier nubs could break off and clog things up so they made them a bit thicker.

Attached is the new housing.
