I assume you will be out this weekend putting those 10 hours on the boat. I don't think you can keep your hands out of the throttles that long!

I had a 99 Viper with the HP500's carb.. I used 30' bravo1's labbed and stock. Top end was 75 to 77 reguardless of load . Boat ran best at midrange, lots of grunt . Also came out of the hole well but lots of bow rise. Always wanted to try a pair of 28's to get the RPM's up as I was at about 5000 tops. This is all GPS.
Also consider a set of five blades. Suggest 26 or 28 pitch.

Mine had the 28 pitch bravo 1 props and pulled just a tick over 5,000 rpms.

What do you guys think this boat would GPS at?

99' vyper with 454 mags

Anybody ever run one with this setup?

I keep looking around for my next boat, hard to beat the space of a PQ for the type of boating I do.

Beautiful boat, it has the same stripe pkg. mine had except mine was black/teal/purple. That being said, with what I know about 34 Vypers(admittedly not much) an educated guess would be somewhere in the mid 60's. with that power pkg. and a light load. But for that price if the boats as nice as it appears to be, you could upgrade power and sell off the 454's to offset some of the expense and have a damn sweet ride.

Just my opinion....but then again, what do I know.

If I was serious about a Vyper I would take a hard look at Tim's old one up in Spring Valley. It's a known entity in terms of condition and performance.

Probably about the same speed you are running now.

But you could put 850s and #6 drives on it and sell you drives to Rich. Then we could re-rig K4M to twin 454 mags!

I think the pictures are telling lies about that boat. Just like the max speed suggested by the ad My friend looked at the boat in April. It needs some TLC. Been neglected for a while. Just his observation it could of been taked care by now.

I am not looking at any one boat individually, too busy for that. Just curious on what the boat would do with that power......

If you are looking for a PQ with speed on the low 80 range look at my 38' Poker Run Eddition Avenger. Its in the classifieds..
Relative to a Viper with 454 power you will not see 70.
