This Sierra 18-6409 is a replacement alternator rated at 90 amps, made for Honda outboards. It is stated to fit the BF200 and BF225. It is interchangeable with the Honda part numbers 31630-ZY3-003 and 31630-ZY3-013, so you can match it to the number on your existing unit.
Our take
The 90 amp rating and the stated fit for the BF200 and BF225 define this alternator, and nothing broader is claimed. If your Honda is another model, the Honda numbers 31630-ZY3-003 and 31630-ZY3-013 are the check.
