I am far from an expert on the blowers but it seems that the weak point of the 575 was the Weiand blower. If you are plannning to keep your boat for a long time you may want to consider going to some TBS superchargers. Then its a done deal. I wouldn't want to trust the other one. This may be a lot cheaper in the long run. I can't understand people who won't stand behind their work, but there's certainly an epidemic of it in performance boating.

Thanks for the reply's so far. I don't want to name the company yet but if they don't stand behind this I will. It took them 42 hours to answer the first e-mail. And never answered the phone, I had 3 numbers. I emailed them late yesterday asking if they were going to cover this under their warranty, which states on their web site as 6 mos. By the way the motor never backfired, there were 3 other people on the boat when it seized.

Sent my 256 Weiand blowers off my 575’s to be rebuilt. After reading how weak these rear brgs are I wanted to be pro active. The engines had 122hours on them. I had them Hard Anodize the Rotors, Hard Coat Interior Case Bore, Add Teflon Stripping, replace all brgs.. When I received them back one of the blowers were put together backwards. They sent me a fedex label and had it fixed and returned in 3 days. Very happy with the performance of the engines after the blower rebuild. Picked up almost 2 pounds of boast and 5 mph. Long story short one of the blowers seized up at the Outlaw challenge poker Run. Boat run great on Friday with no problems. Sat after the first stop took off and cruising around 4000rpm’s when I felt a vibration and I throttle back and the port motor died. Pulled blower belt and blower was seized. The rebuilder says that it must have backfired or had other engine failure for it to happen. I video the tear down and there were no missing bolts or nuts from the injectors or housing. I pulled the heads to make sure there was no other damage and everything looks great. There was a chunk of the rotor in #3 but no damage. I think a bearing went south in the blower and caused the rotors to touch. This also was the blower that was put together backwards and sent back for correction. After talking to him and sending photos and videos of the teardown ,It seems like he is not going to stand behind his rebuilds as he said that they do not make rotors any more for the 256 and I will have to buy a new blower. I’m at a loss on how to move forward. If I sent it back he can’t fix it. Need advise please.
You can put one of our 500hp efi kits on there and i guarantee you wont have that issue.

I have been to DMPE's shop, you would not believe the number of 250/256 blowers on their shelves. A lot of them look just like the pics in this thread. BTW the bearing carriers may shatter on the end caps when the rotors hit. He walked me through all the weak points.
I would have liked to have went with a whipple kit as well but the 871 conversion just seemed easier. I did end up with the whipple low pro innercooler.

Is there an issue with teflon or the use of it it a marine application? Or are you saying it is just not good in a 256?

I have had The Blower Shop, rebuild for me in the past with excellent results.
