REWARD - Missing portion of lower unit

[Sean]

Alright, I filled the hole in the lower unit with Marine Tex and bought a new 15 x 17 prop.
CB, the lower unit on craigslist was from a 87 and was pretty beatup looking, but thanks anyways.
It is the back portion of the skeg that is missing and I am not sure how it is going to effect performance. But it is good to know I can just replace the skeg.
Tomorrow we will be back on the water and hopefully running strong because it has/is going to be perfect out!

Thanks for all the info/help. Hopefully soon I will be able to offer solutions/options instead of just asking questions ::)
