[Public-List] Stern tubes, stuffing boxes, etc.

[Hugh McCormack]

Hi Rick,
 
I'm curious as to why you decided to through bolt the housing?  I (may be wrong) understood that the housing is threaded onto the stern tube and that, therefore, the bolts really only serve to prevent the housing from rotating and loosening.  If the housing is not threaded on then through bolting makes sense to me.  I am looking forward to learning from any following discussion since this is, obviously, a potential problem point and something that I may need to attend to on our boat.
 
Cheers,
 
Hugh

The bearing housing is now properly bedded and through-bolted. There wasn't much meat left in the holes where the old lag bolts threaded in and I couldn't bring myself to launch her again that way.
