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.
