Do you think we could figure this out from hull id numbers? The first 3 characters are the builder, the middle are the serial number and the last four digits are month and year. My 1978 Y33 was YAM000890278, so is it:
- YAM - Yamaha
- 00089 - SN
- 0278 - February 1978
The 33 went into production in 1976. Was mine the 89th boat?
I looked at another Y33 that had YAM000950478 - Compared to mine, hull #95 seems plausible. This might be way off track. I wonder if we could figure it out with a few more numbers. Maybe a 1984 boat number would answer the question.
