Parts Desk Insights

Best Use Case: Use this kit when you’re re-mounting a SeaStar jack plate or when mounting hardware is missing, damaged, or you’re upgrading to a complete matching hardware set.

Common Issues: Double-check bolt length and hole alignment before tightening—jack plate setbacks and mounting configurations can affect clearance. Also confirm the related mounting surfaces are clean and free of debris so the washers sit flat and the nuts seat correctly; follow the jack plate installation guidance and use a torque wrench.
