They are first up for inspection at 200 hours. There are 2 of them. The service manual calls out for testing them (drop them in a cup of boiling water). I just replace them as they’re inexpensive.ftornabe":2g7i4z3w said:

Both my factory service manual and my owners manual specify inspection or replacement at 100 hours. I follow that schedule and replaced mine at 200 hours even though they worked fine.
You can view and download a Yamaha owners manual for your engine at https://yamahaoutboards.com/en-us/home/owner-resources/all/pid-search?viewmode=0. You'll need your model designation and serial number. The manual has a lot of good maintenance info in it, including schedules.
