[Public-List] Stern tube

[vmarmei via Public-List]

Sorry man....
Just me overlooked....If you have a space between prop and housing 
....then buy and cut the new bearing to 1/8 inch short of the prop.
The longer the bearing the better.....still buy bearing to double 
length for another rainy day. Leave the bearing sticking out from the housing.
Also if you do not have space for your zinc anode....then screw one 
large pear shaped one to the hull below the prop bearing....flat face 
of the keel....change the SS set screws in the housing for longer 
ones(3/4") and join your anode with clean/plastic stripped solid 
copper wires to the housing....use counter nuts to hold the copper 
wires in place...I have two set screws and also two copper wires 
connecting anode to the prop housing.
Make sure you drill water cooling / lubricating holes into the new 
bearing after the bearing has been pressed into the housing.

YES.....
Hack-saw.....Buy a 4-1/2 inch long ....this way you have another 
piece left over for years to come.
