77 on gps with 8 people on the boat this sunday in Barnaget bay nj

Re: 353 Fastech How fast ??
 

Fastest one we ever had: 2003 w/525's and boxes, 90.6 on GPS (one of the Formula factory guys was with me, so this is verifiable!). That was after a LOT of prop testing using custom wheels from our F-2 boat.

Donzilla's 2003 with 500's and no boxes is running pretty good also. Perhaps he can elaborate!

Also, you can't accurately project slip factor unless you have an actual scan of your propellers. Merc props in reality scan at at least 1 or 2 inches LESS than what they are marked. Hydromotives tend to scan at much closer to their actual sizing. Your slip should ideally be in the 12% range or so from what the prop actually scans at. If you get your slip this low, then you are running VERY efficiently.

85.4 Radar in a Powerboat Magazine test. 525 EFI's

A terrific boat in every way shape and form. Would the Porter's allow deletion of the Silent Thunder platform and Just install Livorsi Muffler tips? I would put an aluminum Cigarette style platform on if I wanted to myself. Possible?

I prefer the older looking Formulas simply because of the platform. No other reason. I am totally happy with this boat except for that one issue. Same with the 38'.

Afton - I have a 2003 353 with 500's, no boxes, and xz drives. Best mph to date 82.4 with 2 on board and a 1/2 load of fuel. This was done turning 30's inward @ 5200 rpm.

2002, 496 HO's...70.5 @4700 w/ stock non-labbed Bravo 28's. 72 MPH @ 5000 w/stock polished 26's. Labbed 28's no doubt the ticket to 74 MPH, though the 26's work very nice overall! :) Randy
