Drive System

Shaft log, cutless bearing & housing, stuffing box

Mar 26, 2017

The first set of parts from Frank and Jimmie’s Propeller in Ft. Lauderdale.

The drive shaft will go through this assembly to – at the end of the day – make a waterproof transition of the drive shaft from the motor, through the hull, and finally to the prop.  The bearing housing (at the bottom) is a 15lb bronze fitting that bolts on to the aft of the keel.  It’s keyed to connect to the fiberglass shaft log.  Water comes in through the bearing and fills the log, keeping the shaft cool and providing lubrication. The stuffing gland at the top keeps the water in the log and out of the boat.  The log is permanently glassed into the keel and its got to be in the correct position/angle to line up perfectly with the motor.
