what would a 1990 Formula 223LS top speed be with a Mercruiser 454 Mag mpi?

Thanks

Not sure about the mpi, friend has a 89 454/330 and gets about 62, 223 is a fun boat

You might see high 50's with a gps, nothing more.

considering my 242 LS is seeing 60gps with a 454 mag with mild things done to it with prob about the same power as the MPI. i would say you should be in the mid 60's with right prop and not much on board.

I have an 1988 223 LS w/ 330HP 454. Bravo 1. Mine runs 58 on GPS w/ a 23 pitch Mirage @ around 4200 RPM.

I have a 223LS w/ Gen VI 454, pistons, 088 Heads, Cam, Performer RPM Intake, Holley 800 DP Carb, Stainless Marine HI Torque Exhaust System. Runs 69 MPH @ 5100 RPM turning a Labbed Bblades 24P Bravo 1. I know this is an old post but I figured I would put in my .02, Thanks!
