is there a replacement made for B&M/Merc water neck
The water neck thermostat housing extension has rotted thru on my B&M 250 superchargers..its the one that works with the stock Mercrusier cooling system that came on the 420 HP 454 Checy Big Block.. I found a replacement manifold and I have looked at all the weiand and holly acc. for the water neck extension and it looks like they no longer make parts for these units,does any one make a replacement unit that will work?

water neck B&M
The part we need comes from the front of the B&M manifold and connects the Mercrusier cast iron part (thermostat /housing hose manifold from mercrusier to the B&M manifold)
The part that was linked is like the mecrusier part, the part that supports that unit and bolts to the B&M blower manifold is what we are looking for

picture
If you can post a picture that would help, I will try to get one but I am out on the road this week.
Its about 12 inches long 5 inches wide with normal water neck openings at each end. It is shaped like an "S" with one end rotated 45 degrees up and 90 degrees to one side and two small bolt holes tapped into a thicker casting area near one end to support it to the face of the blower

we have the standard intake manifold for the 250 on it now, this is just an extension to adapt the stock mercusier cooling hoses to it...but if we cant find the extension we might have to just go to the bypass system
