Round out the hole if necessary. 

With a rocking motion, slice 

through the Stern Tube hole as 

shown. Cut down 2/3rds then cut 

up 1/3rd  to complete. 

As you drill, check the alignment to 

ensure the hole is in the center.  

Sand the area inside the Hull at the stern 

to help the epoxy bond the skeg 

reinforcement to the Hull. Test fit the 

skeg reinforcement into the hull.

Measure out two inch-wide 

puddles of epoxy parts A & B.

After mixing, fold in the same volume 

of filler material. I’m using Talcum 

Powder. The filler makes the epoxy 

less brittle after it cures.  

Put the filled epoxy on the bottom 

surfaces of the Skeg Reinforcement. 

Put lots of filled epoxy in the 

recess of the hull where the skeg 

reinforcement will set.  

Set the reinforcement into the stern 

of the hull.  

Press the Skeg Reinforcement into 

the epoxy.  

Cover the reinforcement with the 

squeezed-out epoxy.  

Install Skeg Reinforcement 

Sand all surfaces of the Skeg 

Reinforcement. The skeg is the 

square brass tube that supports 

the bottom of the rudder.
