JP RACING INC Sea-Doo 300 Tunnel Reinforcement Plate
Fits ST3 and T3-R Hulls
Protect your investment and ride with confidence. The JP RACING INC Tunnel Reinforcement Plate is engineered to prevent jet pump tunnel cracking — a common issue we’ve seen on both stock and modified Sea-Doo 300 models, including those built on the ST3 and T3-R hulls.
✅ Why You Need This:
Over time and under high performance stress, the jet pump tunnel can become a weak point, especially on tuned or aggressively ridden skis. Our reinforcement plate is designed to strengthen this critical area before problems arise.
🔧 Easy DIY Installation:
Compatible with OEM hardware — no custom parts needed.
Simply apply epoxy and secure the plate using the existing bolts.
Designed for Sea-Doo 300 models without pre-existing tunnel damage (cracks must be repaired before installation).
Recommended adhesive: 3M Marine Adhesive or Epoxy for a durable, watertight bond.
🛠️ Made-to-Order Quality:
Each plate is hand built in the USA, with a turnaround time of 1–3 business days before shipping.
Whether you're racing, cruising, or riding hard — this is a small investment that can prevent major repairs down the line.
