Parts Desk Insights
Best Use Case: A practical upgrade for riders who want to reduce point-loading at the transom by using a dedicated support plate for the top bolt pattern on the jack plate/outboard mounting location.
Common Issues: If the transom bolts don’t line up cleanly with the plate’s holes, re-check the bolt pattern before tightening. Also verify any required gaskets/sealant approach during installation to help prevent water intrusion around the bolt penetrations.
