Parts Desk Insights
Best Use Case: Recommended when you want to reinforce the transom mounting area and help reduce localized stress around the lower bolt points when installing or servicing an outboard on a jack plate or motor mount setup.
Common Issues: If your transom bolt locations don’t line up, confirm you selected the correct top vs. lower support plate configuration and that the hole pattern matches your jack plate/motor mounting layout before drilling or final installation. Also double-check the hardware stackup (plate position relative to the transom and mating surfaces) during assembly.
