B&M Blower service and Holley carb refinish
 

Where to send B&M blowers for service and repair with warranty? (B&M itself?) I didn't see blowers listed on their site... I found no PN stamped on the blower???

Where to send Holley 650s for a dip (Cleaning) and refinish/plating?
4 carbs PN-4777-4 2433 (650 cfm). Is it cheaper to buy new?

These are off of a Hawk 575 package, 1990 vintage, blowers were upgraded from??? Twin engine, 454 cu. Merc original engines with the the smaller blower package from Cig.

Was just down to DMPE. Seem to be really good people and know their stuff. Give them a call.

Chances are you have the B&M 250 Series blowers. I would send them to the blower shop for rebuilds.

Definitely Darrin Myers (DMPE). I have used them several times in the past for B&M blowers. They do great work. You won't be sorry.

And if yours are not already Teflon stripped I'd suggest that upgrade at DMPE.
