T&T: water line to dripless shaft bearings

[JHWardJr at aol.com]

My 2 cents - check the stuffing box temp with an infrared thermometer  during 
stabilized twin engine operation.  Check again when running on  one engine.  
If the temp change is not great, you're likely good.  If  not, run a simple 
cross feed off two tees.  Then they are both fed.  I  might do this anyway, as a 
damaged shaft and/or worn packings are potentially  expensive.
 
An 'unbraked' windmilling prop at trawler speeds does not spin that fast,  
but it is draggy.  Suggest you also check the tranny temps, but I doubt it  will 
be a problem (using your hand on the case is a good method - if you can  keep 
it there, it's okay temp-wise).  The Velvet Drive factory techs gave  me this 
tidbit.  Good luck to you!

Related  question--the boat was built with no cross feed between the two
dripless  shaft bearings.  Thus, if I run on a single engine, the "off   
side" is
not getting a water  feed.
