Model number plate is missing

[HHP123]

I believe the motor to be a 1998 based on the EPA sticker. It is a 200 HP, 2 stroke w/carburetors, Salt Water Series II. Is there another way to determine the model number because the upper portion of the plate is unreadable. The bottom portion appears to be 6G6 5054(9 or 3)3 V.

I have the SELOC manual but haven't been able to tie those numbers to it.

Any help will be greatly appreciated.
