This u-joint bellows is a flexible, corrugated rubber bellows for MerCruiser I Drive 1A, 1B, and 1C. It is installed at the stern drive's universal joint and drive shaft as a replacement for a worn or damaged transmission bellows.
The bellows is designed without an internal rib and corresponds to MerCruiser/Mercury OEM reference 36223A2. The ribless design is an important variant detail, as later MerCruiser drives may use other bellows with a different internal construction.
The product is made of rubber and has a height of 132 mm. The upper opening has a diameter of 110 mm, while the lower opening has a diameter of 113 mm. The dimensions describe the two openings but are not classified as inner or outer diameters.
