Cutlass Bearing
« on: May 21, 2013, 12:22:39 PM »
Less than 5 mins into the 2013 season, I had a cutlass bearing failure.
The rubber separated for the brass and traveled up the propeller shaft. I think the soda blasting put the coup de grace on it.
For those interested the P323 with the standard shaft requires a bearing of 1 1/8 X 1 1/2 x 4 1/2
It's called the IBEAM
A diver pushed the bearing back onto the brass, and moved a zinc down to keep it there.  Fortunately I can limp the short distance for a haul out.

Good information, thanks, added to my list of useful specs.

Incidentally, did you know the correct spelling is cutless (as opposed to the sword!).

Apparently it is a trade name registered by Johnson in the 1960s (Johnson Duramax Cutless Bearings), who pioneered a rubber bearing with grooves in it to allow for water lubrication and self-flushing of the bearing with water to remove grit and other buildup.  Some people claim the name came from cut-less (less cutting of the prop shaft); not sure if I believe that!
