Lets say with twin 500 efi motors, a 42 sonic runs 65 ish, would a 419 run faster considering the steps?

I would think so, it shouldn't be that much slower than a 382. I would think a Kevlar 419 with staggered engines would be a really nice boat. There was one twin 419 built but I don't remember what motors it had. I think they were just 502 MPIs or something. A couple of 1100 Mercs would be really nice.

Don't believe the 419 was ever rigged with twins, at least not from the factory
