Thanks, sdanville. I was able to use your link to look up my Product Identification Number, but not my Engine Serial Number, which has an extra "E" in it, as seen below.
Product Identification Number: BABJ-1,608,742
Engine Serial Number: BEABJ-1,035,329
Model Number: BF9.9D/10D (SHA)
I also downloaded an Owners Manual. However there was no definitive information about the model year of my engine. The owners manual did have a copyright date of 2009. I guess this tells me that the engine is at least as new as a 2009, wouldn't you agree? How did you figure out your model year?
Thanks,
Tom
