Key West
Twisted Kilt had a very expensive end to their racing...... they had a spin out during sunday's final, not sure what happened mechanical failure caused the spin out or the spin out caused the mechanical failure, either way the arneson drives are maybe not as bullet proof as everyone thought....

Looks like the casting failed - as far as I am aware that is rare and I for one will take their reliability record over most other drives!

No. Arnesons do not break. Like Ilmors and other drives...
Talked to Rik at Arneson:
They put larger diameter cylinders onto this boat, 75 mm vs 50mm and when the drives are steer'd fully over the cylinder made contact with the aft edge of the socket housing and cracked it at the boot line.
Should have made a 25mm spacer for the steering bracket on the box to clear the cylinder from the socket housing.
The team won the Championship and the Worlds with no problems. Sometimes new things cause new problems. Customer is very happy regardless.
Two new socket housings, a few bearings and the u.j. parts and its back together.
