gtpartes Catalytic D Plate & Cat Removal Chip for Yamaha 1200 PV66V — Direct-Fit Temp Sensor Bypass

This product is precision-built for Yamaha 1200cc personal watercraft models that use the PV 66V electronic layout. It’s offered as a direct-fit component to replace OEM part numbers and to integrate cleanly with stock or modified CDI units, providing a straightforward mechanical replacement and electronic simulation in one package.

Will this kit fit my Yamaha GPR, XL or XLT 1200?

The gtpartes set is designed for a range of Yamaha 1200 PWC models using the PV 66V platform from the late 1990s and early 2000s. Confirm compatibility by matching the OEM part numbers or the listed model years before purchase.

• Compatible models include GP 1200 R (2000–2003), XLT 1200 (2001–2005), XL 1200 LTD (1999–2001), and other PV 66V 1200 variants.
• Replaces D plate OEM 67B-1465A-00-00 and service numbers cited in the listing.
• Check your hull’s wiring harness shape and CDI type for an exact fit.

How does the cat removal chip affect performance and engine temperatures?

By removing the restrictive catalytic element, exhaust restriction is reduced, which can lower localized temperatures around the converter and open the path for slightly improved power delivery. The chip prevents ECU alarms or shutdowns by emulating the temperature probe signal, so you avoid CDI chatter or warning tones after modification.

• Reduces engine-bay temperatures associated with clogged or restrictive cats.
• May increase throttle response and top-end behavior due to freer exhaust flow.
• Simulates OEM probe signal to maintain normal CDI operation and prevent error-triggered cutouts.

How simple is the installation and what tools are required?

Installation is intended to be user-friendly and requires basic hand tools. The cat removal chip plugs directly into the factory harness, and the catalytic D plate is shaped as a drop-in replacement for the original converter element.

• Plug-and-play chip connects to the stock wiring harness—no complex rewiring.
• D plate installs in place of the OEM catalytic element with standard fasteners.
• Recommended: basic socket set, pliers, and inspection of seals/gaskets during service.

What materials and durability can I expect from this replacement kit?

gtpartes builds the D plate and removal chip from robust materials meant for marine environments and continuous thermal cycles. The components are manufactured to withstand normal PWC operating conditions and provide a reliable service life when installed and maintained correctly.

• Engineered for longevity under repeated temperature loading and vibration.
• Resists corrosion and deterioration common in salt or fresh water use when properly installed.
• Includes one catalytic D plate and one electronic cat removal chip per kit.

Who is this for: This kit is designed for owners and technicians who maintain or modify Yamaha 1200-series watercraft and need an OEM-compatible solution after removing a catalytic converter. It’s suited to riders seeking reduced heat at the converter area, improved exhaust flow, and a clean electronic interface so the CDI behaves normally—ideal for performance-minded restorations, repairs, or upgrades on GPR, XL, and XLT 1200 models.
