SAN DIEGO, Calif. (AP) _ Chip Hanauer set a record for unlimited hydroplanes Saturday at San Deigo's Mission Bay in preparation for Sunday's Miller Hi-Life APBA Gold Cup race.

Hanauer piloted his turbine-powered Miller American around the 2 -mile Mission Bay course at 155.979 mph, breaking the record of 155.172 mph set earlier this year at Pasco, Wash. by Jim Kropfeld.

Hanauer, a three-time national champion from Seattle, also broke the 5-mile Gold Cup qualifying record of 141.788 mph, which he set Friday with a 2-lap average of 149.237 mph.

Hanauer, who has 23 career victories in APBA unlimited competition, is winless in six races this year, but will be bidding for an unprecedented sixth consecutive Gold Cup win in Sunday's 80th annual Gold Cup classic.

The Gold Cup, being contested at San Diego for the first time in 17 years, is America's oldest water-sports trophy. It is awarded at one designated race each season.
