Hi guys,

I am considering buying a 1996 25' active thunder with a stock 454 mag (350HP). Just wondering if anyone has any info on how these boat run in the rough. Also what kind of top speed I might be looking at.

my 97 is great in the rough for a 24.5' boat, best i've seen for speed with my 502mag 415hp stock is 68~69..........guessing low to middle 60's with that power.

That's what I was thinking. Thanks for the input

I can't find any other 1996's for sale. Does anyone know what they usually go for in good condition?

low 30's high 20's.
Mine had a (not orginal) 300hp 454 mag when I bought it and it did 56mph on gps, so you should do low 60's. Now I run 77 with just over 500hp

Nick, Just over 500 HP? How much over? Any other upgrades? Shorty drive? Come on give it up?

Ok here it comes:

489ci(454w/ .25" stroke no bore)
Hardin-Marine Full Retro roller cam set 236/244-.591/.601
Aluminum Edelbrack Marine heads
10-1 compression
Hardin XS Intake(HP 500 style) w/ 850 carb
EMI Thunder exhaust
Stellings Ext box. propshaft 3" below hull, for now...
Labbed 28 Bravo I
77.1mph gps/radar varified at 5250ish RPMs.
I would like to figure out a way to lower the slip a little, and ride flatter on smoother water. Getting ready to lower propshaft .5" this week and see what happens.

HP never proven on dyno. But most say right around 500 or a little more. What do you think? Honestly.

Hmmmm......Sounds like it should be a bit more. Another 25 AT out on the bay with a warmed over 500 EFI supposed 600 HP and hes running a tick under/over 80mph. No box spinning a 28 labbed Bravo One 4 blade I do believe.

which one? Bostick

Gordo, Nevul and some other Tantrum were getting high 70's to low low 80's with Hp 500's, but those were settup for race.
