Jet Boat Engine Mounts and Couplers
Jetboat Drive Line Education
This is the most common modern replacement H-bar drive line for jet boats. The overall length measures 7 1/2" (Â± depending on manufacturer, Panther Drivelines measure slightly shorter), the round register on the flang measures 2 3/8" and the rectangular bolt pattern measures 2" x 2 3/8" typically using 3/8-24NF bolts (grade 8). This type of Driveline is designed to be used with a PTO flange (Power Take Off, pictured below) in order to adapt this universal drive line to many types of engine crankshaft patterns (also flywheel or flexplate). This type of driveline also comes in a 1350 Version (not pictured) utilizing beefier u-joints, h-bar and overall construction. The 1350 measures approx 8 1/4" long, has a rectangular bolt pattern measuring 2 3/8" x 2 7/8" and typically uses 7/16-20NF bolts.
