Promax question.

[SatisfAction]

Is there any difference in porting specs between a 200 Promax block and a standard 200 EFI? I've searched through some microfiches and some of the part numbers are the same so I'm guessing there isn't a difference? I'm thinking of building a Brucato'fied Promax and getting out of the carb game. :)

B&W Boat said the blocks were the same when they did a comparison test around 10 years ago.

Thanks yall. That's just wanted I wanted to hear! :cheers: I can get my hands on a 2.5 200 XRi but it isn't a 7 pedal which is what I really want. A 7 pedal front half and some ECU work should get me what I need I suppose.
