HIN#USKA27MDG990
This is interesting.
MIC: USK (Bayliner: Dandridge, TN)
Serial #: A27MD
Date of Manufacture(Certification): G9 (July)
Model Year: 90 (1990)
I can only go back to 1993 on Serial Numbers
Maxum Customer Care
The "MD" designation in the Serial #:
1993: MD = 2200 SR
1994 - 1998: MD = 2300 SR
1999: MD = 2300 SB
I can't determine what an MD would be in 1990. Bayliner did not use the "MD" serial number designations in the 1990's. So this tells me that it is a Maxum which was built in a Bayliner plant which hadn't been issued a MIC for Maxum's out of the TN plant yet. Therefore, they used the plant MIC which, at the time, was for Bayliner.
I would assume this is probably a 1990 2200 SR model by Maxum.
