You have the first Gen hull? I do not have info about shorty performance on that specific hull. I know on my year the shorties do not add performance with my set-up, there was an OSO member that tried it and the boat did not run out well. There is an 06 353 with exact same running specs/hrs as mine in LEOPA but does not have ITS and the boat did not touch 80. There is something to having boxes on the 353 to get some speed out of it. Have you tried 380 K-Planes? That is next on my list if I can get the clearance.

I have a 2004 353 with 525's, xr's, stellings extension boxes. Best speed on gps was 86.4. Consistently hit 84. I have labbed 5 blade maximus turning out. This was formula factory setup. Problem is I am destroying drives. Any of you guys have recommendation for four blade prop?
BTW, the older fastechs were appx 1000 lbs lighter than the current model which may account for the variations in speed reported.

2000 353 any ideas on props? I would like to try out a new set. I currently have 28 4 blades. Any pros or cons to trying 5 blades? Anyone running similar hp in this boat?

There are a few 353s out there with Merc 600SCI, if I remember correctly they run 30 Maximus 5 Blade props and run 90 mph or very close to it. The extension boxes help also, you might want to call Brett at BBlades. He has plenty of notes on the 353 with different power combos.

I ran 30 pitch 5 blades until just recently (525's w/Whipples/XR's. 780 hp). Best of 97 in fresh water. They are for sale in the classified section.
Just put on 32 4 blades, but have not run it hard yet. Both sets were labbed by Bblades. I expect a few more mph out of the 4 Bblades and for them to be a bit easier on the drives. The only downsides thus far are a l itttle prop blow out with the 4 blades and more RPM at mid range cruise.
Hope this helps.
