These are used MerCruiser # 75832A2 universal joints. This is what can happen when they do not receive grease at least every 100 hours. When these joints failed, they destroyed the bell housing and gimbal housing.

These are our heavy duty  MerCruiser #75832T1 universal joints. They have larger diameter journals and will fit all MerCruiser drives including standard Bravo 1,2,3 drives but will not fit Bravo X/XR/XZ

1996 & up Generation II drives ( serial # OF680000 & up ) call for universal joint #805536A2 which are a Perma-Lube U-joint. These universals are a bit pricey and cannot be lubricated. Our universal #8030 is exactly the same size and quality so this is  what we sell in place of the pricey Perma-Lube u-joint.

The book says to grease these joints at least every 100 hours. The drive must be removed to grease them.

These are sold each. You will have to order ( 2 ) to do one drive.

These come from GLM Marine and are made in Singapore by the Rockwell Corp.
