Fastest SOB hull???

What struggles are you having?

Slow and steady wins the race.

I think some of them may be experiencing the same setup struggles I've been working through.

Mark ran 110 out of the box with a 300r on a Tuff 24 (22.5 degree deadrise at the transom, the progression is 22). He did say the mass of the powerhead Was noticeable and the fat gearcase required different setup. The 28 ran 106 with a 450r. These motors are the future and with only a year or so to figure them out they are already showing us the future.

The Progression is 24, then 23, then 22, changes at the strakes.

Those motors are the future, unfortunately for me the future isn't affordable, lol.

Haven't seen much in the way of these boats with the 400R on them either, At least not pulling any good numbers with them. Or did I miss something?

Here are a handful............... no idea what they weigh versus an XS or R

[Greg G]

Velocity V7 21 Australia .............. 400 R

[Greg G]

Laveycraft 22 XCS stepped V .......... 400

[Greg G]

Force F2 21 Australia ........ 400

[2.5-21]

My question is has anyone set up an SOB with a 400R and had it run better than a 300X? I have not seen one yet gearcase is much bigger too.

Absolutely agree. I'd love to know what he and other folks are doing to address these issues.

Making the top heavy 300R with tons of torque work good on a small pad boat will come with prop and I believe mounting the engine to run some negative trim.

The 2.6 doesn't have what it takes to outperform an X in a single application. The new 4.6 motors are where its at.

100%, there are a couple of Allisons that have gone really fast with the 4.6 platforms.

The 25 Chaudron ran out of the box really well with a 30", Bravo, basically 87 MPH at 6200 RPM. Easily 90±.with time

Like I said before, and I'm not knocking the old SOB boats, I have one, they are limited in design. It's not the engines. They're a little too short and wide, pads a little too narrow to capture the bigger power and they aren't aerodynamic, which plays a huge factor at speeds over 80 and 90.

That's why Tuff redesigned and did the 24', narrower, sleeker, faster.

Any suggestions as to which prop? (Not that any of them are actually available these days.) But I have all winter to find something.
