There has been no official press release sent out by the team to date, this information comes from the official Ellstrom Racing website where JW is listed as the driver.
After a five year absence from Unlimited racing, JW Myers returns to the team where he scored his only win on the H1 Unlimited circuit. In 2005 JW won the Madison Regatta driving for Ellstrom Racing. He also scored second place finishes in Evansville and Detroit.
The week following the Madison victory, Myers got the bright orange Elam Plus high into the Detroit sky in a spectacular flip in front of the Detroit Yacht Club during a prelim. Boat and driver both survived the accident and ended up on the podium with a second place finish in the Gold Cup. Source can be found here
