B&M 250 thermostat housing
 

Any help you guys can lend would be great!

I am converting my NA 509 over to FI with a B&M 250 blower. I currently have the oem recerc pump and thermostat housing on my motor.

My question is this, where can I find a recurculation thermostat housing that will bolt on to the front of this B&M intake manifold?

not sure on the B&M but the weiand's used a adapter to move the therm housing out from under the blower on their marine units, I used a crossover and a short aftermarket housing and worked fine

I think this is what your referring to (although this is on my truck). Should be able to adapt to marine.

the one that came with mine moved it foward and off to the side a little...but blower was smaller...I did not use it as the smaller therm housing cleared ok..

We used to use the housing off the Mercury 800, but it's no longer made.

check out cpperformance,i bought one for my tbs-250blower.it should work on your b&m.

I don't see anything listed on their website that is made for recirculation, just crossover.

Stainless Marine makes a kit 04-111250 for a 250 B&M . It includes a crossover.To run the stock pump you may have to fabricate a custom housing.

That's what I was afraid of.....
