Are all the bottoms the same? I wonder if they all have the same basic interior below?


The purple one Blume mentioned has #6 drives, and wasn't balanced well at all, which made it porpose like crazy. It isn't a great example to use as a reference. "Hot for Teacher" is the best running 900/#6 TS out there for comparison.


There's a 38TS in California with Zul 750's, XR's, and the extended covergirl cabin that ran 105mph for Powerboat Magazine. Probably 100 most of the time?

A friend of mine has one with Sterling 750's, XR's, same cabin, that runs 100.

The bottoms on these boats are the same, and the difference in the "half cabin" and extended covergirl is minimal.

My guess is that the motors the yellow boat has never made 900hp in the first place? That, or they need to try spacers and different wheels. 750hp a side with a dialed in set of wheels on the correct drive height should get 100+ everytime.

Yeah, I wasn't meaning top speed as much as overall handling at top speed.

It's in a few of those SCOPE videos and runs with a great attitude and flys perfect at speed. I don't know what they did different in the setup from the other two #6 TS guns, but it's the right one.

If he dry sumped it he might gain a little, but I doubt it'd be enough to be worth it on that type of boat.

I'm still amazed it took so long to sell that boat when it was new! :eek:

What is the fastest 38' TS? I am guessing it would be a stagger setup..

I don't think there are any TSTG's that are staggered, only strait hulls and the 39's are the staggered hulls.

I believe Greek Lightning told me the big power 38 was so scary no one would run it to the limit. He said sea trial day Neill would not go out on it...

Gotta be this one. 1150's/6's

All of the TS 38's are side by side like Bongo mentioned.

Sorry, this is the only pic I could find. :readinghelp:

2002 38 side by side 725 cobras, xr's on stellings boxs and the boat runs 104 mph at 5700 rpm also in fresh water. when they first did the sea trial in fl with phil and randy they had the boat running 107 mph, the fastest bravo boat ever at the time.... with 900's the boat should run in the 1teens. most likely never had 900 hp, more like 700-750. the arnesons look nice.
