But remember guys these boats are very very weight sensitive. Everything has to be just right to reach these numbers and you will be running loose.
The real world experience with you and 4 of your friends and 100 gal fuel is knock off 5-6 mph off those numbers,
All the boats mentioned are good boats, what you choose will be probably your price range, your brand loyalty and what conditions you drive the boat it. I think you'll find some differences in the handling and cornering in general but especially in how the boats handle in the rough (and everyone's rough is different west coast, LOTO, Ocean, great lakes) between the manufacturers.
Spot on post! My 30/tuned 400Rs ran a best of 127, but my every-day best number with people and some fuel was 120. The best my buddy saw with his 368/tuned 400R rig was 119 with people and fuel on board (we'll know soon what it does with 450Rs after his current repower). I drove the MTI 390X/450R rig down in Miami with Randy (who was kind enough to take me and Chris Mills out in it for a test drive), and it was propped for mid-120s. I will say, it is an amazing outboard boat, and it had a 132 top speed in the GPS, but that was with taller props on it for top-end only when light. My buddy out here in California recently bought a carbon-build 340X/450R rig, and his best speed to date is 129 with 2 people on board and "real-world" 36" pitch props. All these 130-140mph numbers everybody sees online for 450R rigs are not "real" numbers when compared to inboard boats. I'm not saying they won't run in the 130s, but those aren't every-day speeds for them like it is the light powered inboard cats.

Out of curiosity... What do these big boats with outboards accelerate like?

What does the Mercedes boat have to do with an outboard cat? No comparison.

I know with 100% certainty that a WP 360 has ran 135 with "non modified" 450's

def no comparison but it was a good 6 weeks in history of Pyburn setting the margin at 186 and then Gino topping it with the same throttle-man pushing the dial.....

Back to the original scheduled topic.... Skater30 and Hustlerguy pretty much squared away the reality of the O/B cats... For me it's more impressive for these boat to loose single digit mph with people and fuel on board vs. quoting a Hail Mary run in the most perfect and ideal of conditions.. In a boat over 2 occupants, ask anyone in the boat how fast you are running - no one would nail the number unless they could see the display

Interesting....one would have thought that back in the day someone would have ran some modified outboards (maybe quads) on a cat and put up some big numbers....I remember being "wowed" by the 141 number put up by the Victory Hull, juiced computer or not, but it never occurred to me it might be the fastest recorded for an offshore cat.

I think the "Sting" 32B ran 137 w/quad 2.5 Mercs(at 4 gals a mile) but has since been repowered w twin 300s.

My 340x has been 131. The acceleration is better than my 700/6 3212 Skater by a noticeable amount.

Here is a short video from LOTO this past year. I didn't stay in it all the way. We passed the Fountain 34TC and I let up and then got in it again. It had more in it but we were passing our destination(PBC)and a 43OL/1350 boat was already making the turn from the other side of us.

The Victory West 36 ran that 141mph with NONmodified, stock Merc 450’s. Oh it had an air intake vent on the cowling so I guess it’s technically not stock... But the computer and tuning etc was stock when it ran that number.

My opinion for the whole “real world numbers” is that it’s the same for both I/O and O/B boats. The only difference is that the O/B boats take a bigger hit when the weather temps get hot and the load in the boat gets heavier so it makes the O/B boats look worse.
