My 15" is a 13 3/4". Seems like it would be a full 5" taller.

Yes 18 13/16ths :D
18 3/4 inches is correct for the 1/2 inch copper water tube. The 3/4 copper tube is 18 3/8 inches, and you can't run out to Lowe's or Home Depot and buy 3/4 inch copper tubing because the Mercury tube is 3/4 inches OD and has a 1/32 wall thickness. Retail on the 3/4 tube from Merc is like $80.
