Weismann is a beautiful drive but why did they remove them from the Red 54' Hallett and put on Arnesons?

Ya Think?
Merc wants to be the only game in town.
Weisman actually makes a surface drive that resembles the Arneson surface drive. I believe the Hallet had either Arnesons or Weisman's shaft drives on it, not the Weisman drive like what Predator has now.
You guys are correct about the political crap with the APBA and this drive. Mercury Racing seems to steer that ship, or at least they use too, as they were going to pull there sponsorship from the APBA if the rules weren't changed to require all Super Cat teams to use Mercury #6 drives only. Looks like all that crap is over with, so it will be interesting to see if race teams switch to other drive manufactures this season.
Originally, the 54' Herbst boat had the same Weismann drives that are on the Predator boat. I do not know why they changed them. When I was building my boat, I was taken down to the Weismann shop and shown the prototype drive while still in the R&D phase. I looked into putting one of them on my boat, but the price HURT! They wanted 28k for the drive and transom assembly. This did not include any steering or transmission. I don't know where the price is now, but that is what it was about 2 years ago.
The drive spins a 16 or 17" cleaver (cant remember which) and eats about 40 h.p. from the flywheel to the prop. When I was talking to them, they said that at that point, they had put a 1500 h.p. turbine infront of one and it held up no problem. They said that they would intentionally fly the boat and bring it down without backing off of the throttle and the drive never broke. They say that the gears evenly displace all shock versus a vertical shaft taking all of the impact and then snapping. The force is now spread over multiple parts versus concentrated on one.
do they have to have a trans in front of them?
There is a need for a tranny to run the Weismann drives.
Here are a couple of pics of the drives from the Herbst 54.

I wonder if the Weismanns are more efficient from take off?
Didn't see any vent tube on the cav plate for aeration to
support those diesels. Possibly a two speed tranny??
Those drives are awesome lookin'! Especially on the Herbst boat.
