During our summer cruise, I noticed that there was vibration in drive at just above idle speed. I suspected the engine mounts were worn, I also noticed there was a bit of play in the cutlass bearing when I tugged on the prop through the weed hatch.
I had already had conversations last year with Peter at Canal Cruising in Stone, (my go-to outfit for engineering work) about changing the water-lubricated stern tube for a conventional grease-lubricated stuffing box.
It is a big job but one they have experience of doing, I have confidence in their workmanship so scheduled the work for last week.
Cutting out of the old cutlass bearing housing is required to fit the larger diameter shaft and bearing.
|How it was, the Vetus shaft is 30cms diameter. The new shaft will be 1.5inches (38.1 cms)|
The hospital silencer and fuel filter were removed for access. The metal step was also cut off.
|Propshaft and Vetus gland removed exposing the bearing housing.|

|Best not fill the dock yet.|
|New stuffing box installed, using an alignment shaft.|
|Thrust plate welded in position and Python drive installed. I'll need to get in there and repaint the bilge.|
