31 sonic props

I just got a 2002 31 sonic and was wondering what props to try and the speeds to expect it has the 496 375

I had a 31 sonic with 365's in it and ran nicely with labbed 24" bravo props. 67-68mph most days on gps. 69.1 once when it was in a good mood. Engines were right at 5000 rpm's.

My buddy runs 24 4 blades at 69-70 mph with 502 mags

Did the boat come out of Commonwealth? good looking boat, used to be owned by a member on some of the boards (who I haven't seen around for awhile)

I have a stock lh 24 b1 that came off a sonic, sold the rh, i'll cut ya a good deal just to get it gone, then just find a RH. I ran them on my tiger for half a season, then upped the hp.

Look @ the QIV Hydromotives in the classies. I have small blocks in a 28 AT with 320hp per side and the labbed 26's put me @ 71-72 @ 4900. You might see 73+ @ 5000rpms; the diameter is slightly shaved by Throttle up....Awesome props. PM me for any details.

Mine with 502 mpi mags 415hp. runs 70 to 72 with lab26 B1's at 5050rpms and same speeds with stock 28 B1 but at 4400 rpms. Going to get the 28's labbed.
