Umm.... ya idk about that one....
I will agree that Fountains are fast and handle great and all but i would not say they are the fastest, smoothest, etc, etc.....
"42 Fountain w/700's is in the 105's"
With that boat, take off the beak/swim platform/transom notch, and you have a what....? 38'-39' boat MAX....
And i know there are faster 39' boats out there than 105mph with 700's....
Outerlimits goes what? 110-115
Laveycraft goes 106-110
And im pretty sure that Skater is right in that ball park....

The :rofl: at the end of my post was meant to throw so sarcasm at the "right from Reggies mouth" sales pitch I posted. I was mocking Reggie...
The "Fountain Factor" was a poke at the 10% beak factor; again another poke at Fountains...
All in good fun Fountain fans- not like I said Apache or any thing...

I'm at 86 hours, and almost all of those hours are ruunning poker runs. I experienced my first problem last weekend. I broke a prop shaft at 95 mph, and lost a Herring propeller to the bottom of Oneida Lake. I love the package and would definately buy one again despite last weekend.

I guess I have been sleeping some where and missed a press release. When did Mercury change the octane requirement on the 700 SCI? I see on the Mercury racing website its now 89. All my manuals say 91 min. Have always ran 92 or 93. Is this change only for the new models. Mine are 2007's and have 108 hrs on them. No problems so far, not trying to create any either by running the wrong fuel.

Octane Rating
From a previous press release;
"New 1025 SCi Sterndrive
Next Generation EU662 SCi & 700 SCi Models Passport to Anywhere – Savings at the Pump
FOND DU LAC, Wis., Feb. 12, 2009 – Mercury Racing is pleased to announce the release of the all-new 1025 SCi sterndrive engine package. The engine, based off the big block 1075 SCi, features an all-new fuel calibration which enables it to run on 89 posted pump octane (R + M)/2, or (95 RON) International fuel rating, versus the more powerful 1075 SCi that requires 91 posted pump octane (R + M)/2, or (98 RON) rated fuel. Mercury Racing Engineering made the fuel requirement change in response to the limited availability of fuels with the higher octane ratings at marinas and on-water facilities around the world.
The 1025 SCi provides an option for performance boaters who desire big block power, but don’t want to be restricted in regards to where they can use their boat because of limited on-water availability of fuels with the higher octane ratings.
The venerable 1075 SCi remains in the line as an option for those discerning performance boaters who are not willing to give up power for convenience.
Next Gen EU662 SCi & 700 SCi Models
Mercury Racing Engineering has also changed the fuel requirements for the next generation of EU662 SCi and 700 SCi sterndrive engine packages, previously requiring 91 posted pump octane (R + M)/2, or (98 RON) International, to a new minimum posted pump octane requirement of 89 (R+M)/2, or (95 RON). These engine model changes for fuel requirements follow a running change made to the 600 SCi fuel requirements announced last Fall. The 600 SCi changed from a required 91 posted pump octane (R + M)/2, or (98 RON) International fuel, to the new minimum posted pump octane requirement of 87 (R+M)/2, or (91 RON).
The revised fuel calibrations do not adversely affect engine life or performance. The access to the greater availability of lower octane fuels provides consumers with an opportunity for a whole new frontier of exotic locales to discover.

I am on my third SET of 700's with NXT drives. The first two sets were on boats under fourty feet and i had no problems. The last set purchased is on my 43 ZR and i currently am on my third drive replacement on Starboard side. I don't know if it is the X-dimension on the bigger boat that is causing problems. I do know i am getting tired of the same issue! I have noticed Fountain uses # 6's on thier 700 packages. Does anyone know why? Did they have the same issue i am having on thier longer boats?

Fountain was setting their X-dimension too high in the beginning. They changed to #6, which we all know is a stronger drive. Now, their have been many more applications including larger heavier boats than the 43 Donzi.. 43 Nor-Tech for example.. that were set up more user friendly once we learned the capability of that drive.. along with a few improvements that Merc made on the earlier drives from trial and error off the customers.

I just spent several days with 2 boats with 700's.
One is a 39' OL with side-by-side engines, but jack-shafted, close-mounted drives. So far, he has been through ten (10) transmissions, probably related to the driveshaft angle. One side now has a BAM transmission as a test unit.
The other boat is a triple 700 46' OL. His center engine shut down in rough water, and refused to re-start, although it would crank over. Fortunately, he was able to get going and run the 38 miles back to the marina on the outer two.
The boys from Typhoon also reported a number of input shaft failures, but did not give me details or a count. It will be interesting once people start pushing more than 700 hp through these drives...
