Expert Features of the SE429 Replacement

This means the unit is covered regardless of the cause of failure. For instance, it covers damage from hitting a stump or sucking up fishing line. Even running the unit without lubrication is covered under this plan. Thus, you get total peace of mind every time you leave the dock. SEI believes in the durability of their products and proves it with this guarantee.
