I know a guy ,he has a 24 foot Baja. I think its year 1992 or so. He runs a carb. 454 Mag and 1:50 Bravo with a 24 4blade Hydromotive, the thing hits like 72 on GPS !!!!

But scary.LOL
A chinewalking SOB,i can tell you that.:drink:

PS.: he changed exhaust to a Stainless II and runs at 5500 RPM trimm al the way to 5-6 .:party-smiley-004:

Yeah, i have seen that scarab at Shogren, i work about 1/2 mile from them so i cruise on by to see what they have every now and then. Nice boat, but, too much for me right now. they have a nice 25 outlaw also, but it has less cockpit room than i have now, but a lot more cabin obviously. Seems like making the boat faster is going to destroy its resale, and i really dont want to do that before selling it hopefully next year. With all this feedback im now considering leaving well enough, alone.

Bend the needle on your factory speedo, take of the winshield and you will feel like your doing 75!!
Seriously, it's not worth it if you are going to upgrade in the next season or two.

In this economy I really like this speed modification strategy. How do recommend pulling the glass face off of the speedometer?:evilb:
