    Anyone have experience with a flexible coupling on the drive train? J-40 manual says there is one in the system. Never seen one on my boat. Also, manual says there is a cutlass bearing on the engine end of the drive shaft, looks like inboard of the shaft log. Anyone have any knowledge as to whether that bearing is really there?

    Another item with sea cocks- my boat has RC sea cocks (Forespar bought RC (NZL) in late ’80’s) I am capping off a no longer used 1 1/2″ sea cock. Heavy use of 5200 on tailpiece threads is making removal of the tailpiece difficult. However, unlike new Forespar Marelon sea cocks, the body of the sea cock is in 2 pieces and the upper piece with the ball valve unscrewed easily. NO 5200 OR OTHER SEALANT. BEWARE. The hose connected to the tailpiece of the sea cock is what secures the sea cock in place!
