1.5 Litre Stock

1.5 Litre Stock ("T" class) hydroplanes race at 90+ mph. These small, light and racy hydros are a great starting point for young drivers or for budget teams. They generate all the competitive excitement of the bigger classes, but their smaller size, virtually stock components, and dependable 4 cylinder Toyota engine add a degree of economy to following the boat racing trail.

1.5 Litre Stock Specifications

Minimum Length:14' 6"
Minimum Weight:825 lbs including driver
Engine:4 cylinder Toyota SOHC 1587cc (97 cubic inches)
Fuel:Gasoline per APBA specs
Approximate Speed:90mph
