Used on all K&B 3.5 outboards
NOTE: Very early 3.5 outboards did not use a screw in bushing housing. They simply clamped between the two lower end halves. This type is no longer available and you are asked to upgrade your lower end halved to the newer style.

Assembly includes: Prop shaft, drive dog, Teflon thrust washer, threaded bearing housing fitted with 2 bronze bearings.

NOTE: The prop shaft housing has a left hand thread.
