Just curious what to expect out of it speed wise. 454 mags 23p props. Anybody have any experience with one of these? Thanks!

low 60's would be my guess.

my 87 265 with 350 mags was a 64mph boat

i know a guy that has an 86 with 500s bumped a little bit and hes running mid 70s.

My 280 runs about 68 maybe 70 on the perfect day. Same setup 454 mags with 23p labbed props. Would say low 60's for the 320.

I know Chestnut!
Dude, your boat should run 65 with a light load of fuel & the propellers turning in & the wind at your back.
If it don't we can make it! I know a guy......

Also, you hitting Eldo tomorrow? I'll bring your tools back to you.

Not gonna make it out today...too much work to do before LOTO trip. Good luck out there in this wind!
