PAD or STEP bottom is what I meant to say

Kevin you missed my point . I'm not wondering why I'm not going faster than 84 mph. That's an easy one. More power, higher x dimention , 3 blade props.......
I'm wondering why my boat isn't faster than another 35 sonic with much less power? . That's why I asked for everyone's speed and set up without the BS.

I was talking with a guy with a 38 fountain . Older straight bottom boat. 600 hp. He said the boat does 88 mph . Next time I saw him on the water I was wondering how that boat was doing 88mph while I was walking away from him and my boat was running 82. LOL
I know the answer already, he was full of **** hahaha

yea lots of b.s. speed numbers flying around.... I have a friend who had 3 sonics, 26 prowler 496 ho, 31 ss twin 496 ho, and 386 twin custom built 502's with blowers making neighborhood of 750hp each. He pumped tens of thousands of bucks into the boat and ended up with a top speed of what a 38 fountain would have prouced with stock merc 525's. Now the sonic looked awsome and sounded like a total moster! But he was NEVER satisfied with the speed of the boat and sold the 386 that he pumped 60-70k into, and that was only what he put into the power. I think 80+ mph on any sonic is very respectable and surely nothing to sneeze at.

I just ran the Manhasset Bay Poker Run on Sunday so I may stay on the north shore for another week but if you see me out on the south shore stop me and say hello....which Sonic is yours ? any pics so If I see you I'll know it's you......

02 31SS, 496hos, 26p labbed mercs, 75mph 5050rpm, normally see around 73-74, but also don't run 5000rpm for long, but 4800 is another story @ 70-71mph

Anytime we run in snot, we leave everyone behind, even wimps with bigger fancier stuff:)

i want to run 100 mph, going to get -2 shortie drives and run e85 with more boost. i have to power to do it i just need to set the boat up differently. i ran the boat tonight 86mph still pushing the bow. i have props getting labbed now which should put me to 90. well at least a have my fingers crossed, then over the winter I will get new drives and see if that does the trick.
i think the drives are way to deep

do you run extension boxes ? My boat came set up with XR's, extension boxes, and a spacers (i think 1"). I don't know how she would run without that stuff but I would guess it is there for a reason......... And beautiful boat by the way, I will know it is you for sure when I see you........ Good luck on the 100mph club, I would love to see you get those numbers in a 35' Sonic.........

2003 31ss 575sci's, superchillers, modified ECM's, ported heads, full roller cams, and other "assorted" goodies :)
Running XZ's at the time, now running XR's... a tad bit slower as they take at little more HP to turn... still mid 90's.
Boat is also fully loaded ammenity wise too.. a/c, fridge, microwave, tv, dvd, ect...

The GPS does not lie...

Water was 2' chop, fuel was almost gone, 1 passenger, wind behind us, 6000rpm (rev limiter set to 6800), 32P bravo 1's labbed, starved myself for a week to loose 10 more lbs lol...
