Outer Keel/Stem joint

[62cruiserinc]

I have posted previously a picture of my current outer stem/outer keel joint, which is a butt joint with a hole through it (1962 Cruiser Inc 202).

I am replacing both the outer stem and outer keel. How should I join the pieces?

A butt joint with sealer between the two pieces?

A scarf joint?


Thanks
Steve
