Since 1975, T-H Marine has supplied professional-grade components to boat builders worldwide. Our decades of innovation and craftsmanship help builders streamline production, reduce maintenance issues, and deliver the high-quality performance that today’s boaters demand.

This MasterCraft collection features the plumbing, rigging, and finishing hardware most often used across ski and wake models—push-in drains, splash-well drain tubes, scupper check valves, barbed elbows, deck plates, and non-locking hatches. You’ll also find frame-top battery trays and select LED courtesy lights that provide safety and visibility in tight compartments.

Built for repeatable installation and long-term reliability, these parts help MasterCraft builders achieve tight seals, clean finishes, and efficient production. Every T-H Marine component reflects our commitment to precision, performance, and quality at the OEM level.
