C-40 CR (AquaSaw) or C-40 CR Custom (AquaSaw XL) Lower Shaft Assembly. Includes all the screws, O-rings and hardware needed to replace your Shaft Assembly. This assembly differs from the standard C-40 Lower Shaft Assembly in that the block is hard-anodized to help resist corrosion, and can be used on a standard C-40 if desired. Note: when installing the new assembly, do not over-tighten the screws that hold it to the case. The rubber rings allow the assembly to rock as you adjust the tension, so the screws should be no tighter than necessary to make a water-tight seal.
