[Public-List] cutlass housing replacement

[George Dinwiddie]

Greg,

How awful!

I'm told that Buck Algonquin makes a cutless bearing housing that fits. 
See http://alberg30.org/maintenance/MechanicalPropulsion/CutlessBearing/

If you can't replace, I think brazing and rethreading is a smart idea. 
If in a hurry, you could use 5200 when threading the housing onto the 
stern tube, but I would think you'd want someone holding the stern tube 
on the inside when trying to unthread it later. In any event, 5200 
softens when the metal is heated with a torch.
