Congratulations and welcome aboard. Anyone that uses a toothbrush to clean their boat is a-ok in my book.
Like "Split", I spent many yrs on the Mighty Hudson, my formative yrs, to be exact. Of course, based upon your location, I imagine you'll be spending more time on Lake George than the Hudson. Nice! Good luck with your restoration.
CONGRATS.. Many years in Poughkeepsie on the Hudson River... Now Chattanooga , Tenn retired.. That gal is cleaning nice.. Your got a good supply of TILLER motors.... Maybe if that letter “X” is the month , Roman numeral equal 10 for Oct . ? Many manufactures went to odd code in the 60’s .. Glasspar was quite good in the late 50’s early 60’s.. Then 67 went to long crazy letters.
If that is a GC instead of G0 it would be a '62 model.
I think the P means painted and the L means lapstrake.
The X is the month but I haven't found the breakdown for it.
Post some pics.
