But how much are the steps adding? No one is saying that steps don't add mph. It is just the percentage being questioned. No idea what the Sutphen weighs with blower motors and 6's, but the Sutphen site lists the new '40 with 525s and Bravos at 9180 lbs. It seems safe to assume the '39 weighs a bit more with the big motors and drives. The boat has run 107 and it isn't staggered, it isn't dry sumped with the better lowers and has less horsepower. How much do all of the pre-listed ingredients also add to the mph? You are talking a 20 mph difference which is a large amount when you are in the 100's, but it isn't all coming from the steps. Certainly the percentage will change on a case by case basis.

I see this thread has been "hijacked again". I guess I am supposed to say something at this point. So here goes. Since I'm not about to spend another $75-$100,000 on a 92 boat that like most of us I have way too much money into already. This is purely speculation mind you. But........I read on here, I would think, where Reggie said a full stagger depending upon the boat was good for 10-15 mph. If I were to stagger the Sutphen and conservatively let's say I gain 7 mph. Convert my drives to dry sumps, change to swept back lowers, and better props. How about another 7 mph. Increase the horsepower the other 150 to get up to the 1075's maybe that's another 3 mph. If my math is right that's 17 mph. On top of the 107 we have run (never mind the I think it will run 110) that's 124 mph for a 1992, straight bottom resin bucket, as Shaun likes to call our Sutphen's. That's not too bad!

For the record my arguments were strictly geared towards comparing stepped top guns to non stepped top guns. Many are tossing out other makes and models...as I said maybe there step technology is more efficient than cigarettes. That wouldn't surprise me...
