Re: what year is my motor?
The last 100 was in 2000, until 2006 when there was a 100 EFI.
Also, your serial number is no good, the second digit should be a letter, I tried C, but nothing came up, D came up as a 75/90 3 cylinder.
From 87 to 2000, the 100 hp engines were 4 cylinder. How many cylinders does your engine have, and can you check the SN again to verify it.
