370 hp...I would like to get my hands on that one!!!:beer:
What would the gears be in the unit it may have on if not the sporty convertion? Your right Brad said 57 but no one has accualy sat down and realy delt on in yet. Sure a mean package.The boat should have no problem running 100+ fully loaded. Them hydrotec motors have some awesome torque, 370 HP is ALOT of HP also. I don't think this one has the sportmaster on it so it will be limited unless they get the conversion mod done.
thatboat only ran 96,i helped him back to shore with the broke neckTodd had that very boat at the Jackson, TN boatshow a couple weeks ago. I went over and saw it and hung out with him a couple hours. It didn't have a Phase III on it then, was a stock 250 on it because he wrote 87-88mph on the F/S sign because so many people kept asking. He also had a price of $57k on it. I remember that boat so much because of those awesome colored seats. :cool
That phase III WOULD be a rocketship ride on a 21 SUB, I can't imagine hangin one of these big barges out at such speeds. That's ALOT of boat to have flyin. They for sure require more "attention" than any of the smaller boats doin over 85, I can't imagine a hunnert+. :cuss
The 103mph 21 was a 2+2 with a 300X and I "think" a 27 or 28 Trophy on it. It was at the 50th Anniv. Rally because the day before the parade we were up on Cherokee when he spun it, throwin him under the passenger console, knocking him out and cracking a vertabrae in his neck. :gasp

i dont see any one running 115 with the yamaha gearcase unless they have some special gears made or they found a way to turn that yamaha 8000 rpmAs far as the gearcase goes. I know the Hydro-Tec modded HPDI case actually ran faster than a stock Sportmaster on a Stroker. So the Sporty mod is NOT a must to attain max speed. Now log-term durability may be another question, the jury may still be out on that.
I have NO doubt that if the 370 HP Hydro-Monster motors can push a Stroker to almost 115 mph (which IS documented), then IMO 108 for a XB21 should be doable. With the ability to hang BIG power on her tail, the XB21 "may" surpass the XB2003 for 2nd place as the faster basser in the Allison family tree.
