100990, 100993 and 100999. what's the difference?

[grrrrrant]

I have narrowed it down to my motor being 1 of the 3 mentioned models. Can anyone tell me the difference in them? I need to figure out which model I own.

Thanks

Can't tell you the difference between those 3 models. However, if you need to order parts, look up the needed part, click on the part number, or name, and that will tell you all the motors that part was used on. That part might be the same on all three models.

If you need to know which model for other reasons, the model number might also be stamped on the powerhead, maybe around the carbs.

Good luck.
