Yup, you had better name it NOW!!!
Like 298 Vista said, if you use it, it's going to get dinged up. Best thing is, now you have a few, so the rest aren't so bad!

I have already put my fair share of nicks & scratches in ours as well.
About the prop, if you are going to a stainless, a friendly fellow from down under on this board, goes by the name of Ardy, is running a Mercury Vengeance with good results. I believe he is running the 19" pitch version of this prop. I am running an Enertia, which probably is giving me about the same results as Ardy. For the massive dollar difference between the two, I would just stick with the Vengeance, just so you don't cry as hard if you ding it.... (I've been close already

). Other options would be a 4 blade alpha 4 aluminium, but I would guess you would loose a few mph at the top end, but gain some hole shot.
Yup, Trout Lake is deep, but there are some spots to watch out for!
