Quicksilver Long Steel Hub Bravo Drive Coupler

The Quicksilver 8M0098796 is a genuine OEM flywheel-mounted engine-to-drive coupler with a long steel hub, engineered specifically for Mercruiser Bravo I, II, and III sterndrive applications. Featuring a round shape and flywheel-mount design, this coupler provides a reliable mechanical connection between the engine and drive unit on a wide range of high-performance Mercruiser engines. It is a factory-original Mercury Marine part, not an aftermarket alternative, ensuring correct fitment and durability to OEM standards.

This coupler is compatible with the 8.2L MAG and 8.2L MAG HO engines, and also fits the 357 Stroker, 383 Stroker, 500 Bulldog, 540 Stroker, and 575 SCi engine configurations.
