What are some opinions and advice on a 357 formula sr1 with 575hp bulldog 540ci mercs with a ssm #3 drives? Pros / cons? Good / bad?

check transom out real good.the engine drive package sounds super reliable.just check the engine out to make sure its sound.

Will do. Thanks

19 spline props are getting kind of hard to find. Suggest rat-holing a pair if you run across them. 26-spline adapters are $500.

Is this the old 575 merc engine that came with stellings headers and solid flat tappet camshaft, or the later 540 bulldogs?

They are original engines and drives that came in a 1989 357 formula??? They are mercs and they are 575hp, they have headers and supposedly bulldog supplied them to merc according to an ex Mercury tech???

Rare combo for a Formula... Sounds cool yes check stringers and transom big time they rotted a lot, depending price may be a good buy no matter what, if you pass PM me

I just found the drives are #5 SSM's. Is that any better prop wise?

Ok. I will definitely check out for rot and get boat surveyed.

Are you SURE? seems like way too much drive for that power, any pics? might be but I would be surprised to see 5's behind 575's
