That number they gave you is based on light loads etc. I would say 63 mph with the mag and maybe 68mph with the HO. Just my opinion I don't own the boat you just received. I think during the summer you lose 2-3mph depending on temp.

[Dribble]

Makes sense. My 23 will just squeak over 70 with the 496 Mag. Three people and 25 gallons of fuel. And I understand the Lavey is a true 24 running surface. My Caliber is 21.5

[jbtrailerjim]

MY Ultra has the 496 Mag in it. The fastest I've seen on the speedo with 3 people and about 25 gallons of fuel was 71. They told me I would only see about 2-3 mph more with the HO. I know the Ultra 247XS is narrower, has less running surface, and is lighter than the Lavey 24. So, it sounds like there probably about right with there assumption.

Jim,
what size prop are you runnin with that? What rmp?

[PlayTime]

HTM SR 24 - 496 Mag - 24p - bravo if all conditions right and one passenger has seen 66.
Hope that helps :cool: my .02 cents go with the HO everybiit of power helps. I'm assuming youll finance so it will be worked into that payment :D

[rivercrazy]

My 25 Shockwave runs 70-73 depending on which prop with the 496HO. Their estimates don't sound too far off to me

[Phat Matt]

I've got a 24' signature commander, 496 mag, bravo one 24 pitch prop. The best I've seen is 65 with a full tank and 3 people in the boat. That was at Elsinore. In Havasu I top out at about 62...for now. This will be my 3rd season on this boat and I'm ready for more power. I say buy as much HP as you can afford!

[Mandelon]

I heard the 21 Lavey will just bump 70 with the 496 Mag HO the 24 most likely would be a couple mph slower.......

[TheEduKATor]

I've got a 26' Cat with a Mag. Top Speed with two people and a half tank of gas 62. Fully loaded with 8 people, and all the carry on extras that comes with them, 75 gallons of gas, two ice chest lockers full, top speed 53-56 mph. I'm not in a hurry, the party doesn't start until we get there anyways, but the HO would have been nice to get me plane faster.

My 21 Lavey XTSki (CG is further forward than the XCS, and it's a walk through open bow) with a 375hp MAG has GPSed at 68 @ 4800 with a 24" Bravo1 Prop, two guys (one big ;) ), and half fuel. I think it'll do better with some prop work. HO should be over 70 w/o any problems. The 24 w/ the HO (in a cuddy configuration) should be at 70, the 21 has delta pads, the 24 is a true V-bottom, although it's a little longer. Safe to say you'd be near 70 anyway.
RTJas :D

[Phat Matt]

Hey EduKator...it's Matt, you ready for the river?

[TheEduKATor]

I've been ready since the Regatta, but haven't made it out.

[Phat Matt]

This weather has been killing me. I can't wait to be back on the water. We will be going sometime in April for sure! We were talking about Del's last week at work and I was saying I have got to get ahold of Russ!

I'm running a Bravo 1 24p 4-blade. Sorry, I don't recall what rpm's I was turning.

[THOR]

jbtrailerjim,
I will be running a 26P or 27P on mine when I get it. I should see some good numbers spinning it around 5100 rpm.
We'll see.
RTJAS,
Explain to me the benefits/downfalls of a delta pad.

Is this a test? :D Are you calling me out Craig? :D Because I'm not a boat designer ya know?!? ;)
Here's my logic and experience (although I very well could be wrong). The Delta Pad supports a load better and is more stable, w/o the "need" for trim tabs. A non-delta design would probably have better rough water ride, because there are no flat spots in the bottom. I the lack of flat running surface also alllows the boat to get further out of the water in a WOT situation.
My Lavey has two delta pads, a traditional one at the transom, and another small one at the base of the second step. Depending on load and speed, it's usually pretty easy to bring the boat into a flat ride on the pads. Although there are exceptions, and if I build the boat again, I'd have tabs put on. I had them prewire for tabs, so I still may upgrade at some point. Just for times when I have an unbalanced load and we're going slow.
I'll snap a photo of my delta pads in few minutes....
Here is the main pad, extending from the transom, to the second step.

Thor,
What boat kind of boat did you end up buying? Are you going with the Mag or the Mag HO?

Jas,
I believe the 24' Stealth has a delta pad if I'm not mistaken.
I thought that delta pads were for stability also until I over heard a bunch is idiots at the boat show spouting off crap.

Okay, I wanted to wait until it at least hit the mold, but I bought a 247. I went with the HO and Steve and I are putting a labbed 26 or 27P on it. I also went with a little different interior stuff, but not wild by any means.

Sweeeet!!:cool: Good choice. How long before it's done?

RD <--- callin out Thor.. ;) :D j/k
something like---
"duh, its harder to wake board with a boat that has a delta pad because it wont stay on the pad at low speeds"
"my buddy has a delta pad and it is great at low speeds but it doesnt handle well at the top end"
"there is no need to have a stepped hull with a delta pad"
the last one is the one I dont get at all.
THOR <--- officially of the Budweiser hot seat

[prosthogod]

I've got a HTM SR24 '04 with a 496ho. Just 2 weeks ago with 2 people in the boat and 1/2 tanks we pulled a disappionting 71mph. That's with a 26 prop, XR drive.:( :(

[THOR]

Well, depending on your rpm, a 26P spinning at 5100 rpm with 10% slip should run around 75 mph, especially with a tunnel.

I really don't think you're going to run a 26P @ 5100 w/ 425hp though.
RTJas :D <-- calling you back! :p

Why not? Isnt the rev limiter at 5150 rpm?

Well shit, put a 36P prop on and go 100 then! ;)
RTJas :D

[THOR]

he should be able to spin a 26p with an HO, if not use a 28P:p

[OGShocker]

Thor, what did the boat in your test ride boat have on it? How did it perform?

[25Elmn8r]

The rev limiter is 5150 but aint no way your gonna turn a 26 let alone a 28 to it with only 425 horses. I can turn a 26 to about 4800. Granted I don't have the HO but I don't think the 10 hp will get you that extra 300 rpm.

I was only joking about the 28P. But the 375 horse mag will spin the 24P off the limiter. THe labbed 26P with the HO will hit 5000 rpm. It wont turn the 28 though.
What motor are you runnin?

375 horse mag ran about 70 mph with a light load, real light. That is with the 24P too.

Not in any experience that I've had or heard of. 375hp Mag (like I have) runs no more than 4800 and change. My 22P Bravo will (on occation) hit the limitor though.
Are you talking about a box stock 24P Bravo? On what hull is that hitting 5K w/ a Mag?
RTJas :D

[THOR]

Jas, the hull weighs about 3300 lbs if I'm not mistaken. I heard its a little lighter but I doubt it. But, previous owner have told me that they are seeing 5000+ rpm with a labbed 24P.
Without getting in their boats, this is the only basis for my opinion. When I run my labbed 26P I will be sure to let you know the speeds and rpms. :D

[25Elmn8r]

I've got the 502 mag, which is 415hp. 10 shy of the HO.
3300 lbs is pretty light. It might be able to spin a 26 up, but i don't know about 5150.

[Sun burners]

I have a 502 and the 26" prop I was running was shy of 5k on IDEAL conditions.

I am merely stating the factory specs. It has been said that the limiter is set at 5150. I doubt it. 4900 to 5k sounds about right.

[rivercrazy]

Just for a point of reference, with my 25 Shockwave Tremor and the 496HO motor, I can spin a 23P Rev-4 or a labbed 24P Bravo 1 at about 5,100 rpm fully trimmed out with a relativelyl light load.
To turn a 26 at 5,100 rpm is gonna take more power than a 496HO IMHO. :D

How much does your tremor weigh RC?
I am just going on what Steve at Ultra is saying. BTW, I am having it labbed too. That should free it up a little bit.

[rivercrazy]

Shockwave's 25 is a full length 25'er without the swim step and a full 100 inch beam. The factory rates it for 4,300 pounds but mine is heavier due to all the dam stereo gear:D
If your boat is a bit lighter maybe you can turn more R's?

[THOR]

Well the 247 is not a true 247 with the integrated swimstep. It only weighs about 3300 and has a pretty aggressive bottome. Only a 96" beam too.

You realize the 425 hp over the 375 hp in the mid-range when you jump on the throttle. Top speed has too many variables to base your decision on. The extra 50 hp from the HO should come with the upgraded Bravo X drive. You get a lot for the couple extra bucks and you'll never kick yourself for not taking the upgrade from the factory.
My 24' 4" Essex with the 496HO (4,500lbs) + 80 gal. of fuel (480 lbs) + 3 fat adults (600 lbs) + numerous cases of beer (100 lbs), matched with a 24 Bravo 1 prop = 65 mph (gps) at 4950 rpms.
