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

Carreraboy.............. are you looking at the repo one in CT?

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.
