I obviously had a strong 502 in my boat cause I have seen 272 speeds posted in many threads both here and other sites. I also added stainless marine exhaust and Vortech flame arrestor, which really allowed the motor to run better.

Lots of sanding and regelcoating.

I don't beleave Baja puts hook in the pad or running surface. I don't beleave his prob is in the bottom. I think he needs to change props. I'm going through this same problem. Ran a 24 Bravo 1 to 5200 rpm's and 66 mph on a 252 islander. But it seems like the boat really doesn't like the 4 blade runs to level. And the slip #'s seem high to me. Thats why I was asking what yours where.
My motor should be putting out around 450 to 490 hp it's not a stock 502.

heres a pic of mine running at WOT with the 4 blade

Agreed. Some prop testing is definitely in order. I can not believe JC is not on the rev limiter with that prop!

Call Julie at Throttle Up. They are the best! They have a great prop test program.

And if you want to remove the hook I would look into having a profesional do it. Will cost around a grand or more to have it done. I was told around $1500 to remove the hook and blueprint the bottom. Haven't done it yet.

Damnit guys......you are cutting into my boating time. Got to go. Later!!

I cant imagine how that boat could spin a 22? I have the same set up
with a 26 hittin the limiter once in a while. I'm trying a 28 tommorrow.
The 27'S on my lake are claiming 65 with 454 mags. Probably not gps.
I would think there are a couple to be had. I've hit 67 gps, but then
a 27 fountain is half the size of a 27 baja. I'll be on st.clair tommorrow
if anyones out playing. Look me up. I'll have her wear the thong so I'll
be easy to spot. JC

Fountain 27,
Everyone including me will be at muscemoot bay for the big raft party. I should be tied to a 33 and 37 sundancer. I have blue and gray graphics flying a pirate sock from my ship to shore antenna. I will look for the thong, but I'm sure I'll see many out there. I heard as many as 1500 boats for this event.
I will look for you.
