I own a 19ft Hallet skiracer boat with Twin turbo 429 BB Ford engine and Casale v -drive with 1.48:1 gears turning a 3 blade 15 inch RH rotation propeller. The v-drive are driven from the front crankshaft pulley. I recently damaged the gears and replaced them with a new set of gears. The gears I received are stamped LH and the gears are cut in the opposite direction than the standard gears.I can not find any reference or information on websites I have visited for these gears.
I fitted these gears and they seem to work after I made a few laps around the lake at lower speed than normal . (Here in South Africa any information about v-drives is non existent.)
Are these gears suitable for high speed circuit racing and endurance races of 120 kilometers or more ?? .As far as I know you need a counter rotating ( LH Rotation ) propeller if the v-drive is driven from the flywheel at the rear of the engine. Please Help.
