good replacement part, great price.
This was purchased as a replacement for the broken one on our outdrive. It performed exactly as expected, bringing the steering force back to neutral. Great price when most boating related items are extremely inflated.

Wrong application
Posting indicated it would fit my outdrive. Turns out it didn’t Unfortunately, by the time I got the storage and tried to install it it was past the Amazon return policy
