Mine was a marine kit.

Thanks guys

call nickerson performance.. I did 2 250 b&m's kits through him . He reworked dominators, jetted them right on for my alttitude . i have been real happy running 6.5lbs for 5 years.

I have a B&M 250 with a Super Chiller on my personal boat. I had it rebuilt by the Holley shop when I took it in on trade from a customer. I put it on 3 years ago and haven't had any problems. That being said, the Blower Shop unit is a very nice piece. If you have your heart set on a 250 series and have the money, I'd definetly go with the Blower Shop unit.

I will be putting 2 complete 250 B&Ms with carbs & flame arrestors on Ebay this weekend if interested.
