Rareelectrical Exhaust Manifold Gasket — Yamaha 1200 Jet Boats

This gasket is designed for Yamaha 1200cc, 3-cylinder, 2-stroke engines used in GP1200 and related jet boats. It replaces the OEM part numbers 65U-14613-00-00 and variants listed in the description. It is best for owners replacing a worn gasket on GP1200, SUV1200, XL1200, and similar models from the late 1990s. If your OEM part number matches, this gasket provides a direct fitment and is suitable for boats with Power Valve configurations.
Who it is best for: Yamaha jet boat owners seeking a OEM-equivalent gasket with straightforward installation. Why selected: The listing explicitly covers multiple GP1200 and Waverunner variants and emphasizes compatibility with the Yamaha 1176cc engine family.
Limitation: Verify exact OEM part number before purchasing to avoid cross-application errors. Some older Yamaha models vary by year and regional production, which can affect fitment.
Rareelectrical Exhaust Manifold Gasket — Mr-1 1052cc

This gasket fits Yamaha Mr-1 engines in the 1052cc class, used across VX and MR-1 Waverunner variants. The listed applications cover Vx, V1, and related models from 2005 to 2015, with a primary focus on 102Hp-class performance. Choose this if your engine is a Mr-1 1052cc 4-stroke and you need a gasket that aligns with the 4-cylinder configuration and the 1.0L-class displacement.
Best for: Yamaha VX and MR-1 owners seeking compatibility with the 1052cc engine family. Why selected: It explicitly lists MR-1 applications and the 1052cc displacement, offering a reliable match for common modern Waverunners.
Caution: Model-year variability can impact fitment; confirm the engine code (Mr-1) before ordering.
Rareelectrical Yamaha VX 6D3-14613 Gasket — VX Series

This gasket corresponds to the Yamaha Mr-1 engine family with 1052cc displacement and is targeted at VX-waverunner models in the 2005-2015 window. It is presented as a newer version of the 6D3-14613-10-00 and is offered for models like VX, VX Sport, VX Deluxe, VX Cruiser, and AR210 variants. Best for: VX-series Waverunners needing a 6D3-14613-10-00 compatible gasket. Why selected: It matches updated OEM part numbers and supports a wide VX lineup.
Limitation: The description references various model years; verify your exact OEM number and engine family to ensure proper fitment.
UpluMarine MerCruiser Drain Elbow Kit

This kit focuses on drain elbow replacements for MerCruiser V6/V8 inboard and stern drive systems. It includes a 4″ exhaust elbow, water shutter, hose fittings, and multiple gaskets. Best for: MerCruiser inboard owners performing maintenance or resealing dry joints. Why selected: It consolidates several related parts into one kit, simplifying a common maintenance task.
Limitation: It is a repair-oriented kit rather than a single manifold gasket; ensure you need a full elbow replacement rather than a simple gasket swap.
Rareelectrical 6D3-14613-10-00 Gasket — VX/Waverunner Updates

This gasket targets Waverunner models from 2005-2015, aligning with 6D3-14613-10-00 part numbers. It serves VX, VX Sport, VX Deluxe, VX Cruiser, and AR210/SX210 families, including the 1052cc inline-4 Mr-1 engine configurations. Best for: VX-series owners needing updated OEM-number compatibility. Why selected: It reflects superseded-to-updated part transitions, aiding long-term compatibility.
Limitation: The product description mirrors other 6D3 variants; confirm the exact OEM number and year range for your specific boat model to avoid misfit.
Buying Guide: Key Purchase Considerations
- Engine compatibility: Verify engine type (Yamaha 1200, Mr-1 1052cc, VX 1052cc, MerCruiser V6/V8) and the exact OEM part number listed by the manufacturer.
- Application scope: Consider whether you need a standalone exhaust manifold gasket or a complete elbow/drain kit to address multiple maintenance tasks at once.
- OEM vs. aftermarket: OEM-number-mair matching parts reduce the risk of fit issues; however, reputable aftermarket gaskets can offer comparable reliability when the OEM number is clearly supported in the listing.
- Installation considerations: Look for gaskets and kits that include or indicate required accessories (bolts, seals, waterboxes) to minimize additional purchases.
- Model-year coverage: Some part numbers cover wide ranges; others are limited to specific years. Double-check the year range against your boat’s production year.
- Quality indicators: Favor products that specify material (gasket composition), pressure tolerance, and corrosion resistance, especially in saltwater environments.
FAQ
- Q: How do I know which gasket fits my Yamaha jet boat?
- A: Check your OEM part number from the original gasket and match it with the part numbers listed by the seller. Engine family (e.g., GP1200, MR-1) and displacement are also helpful.
- Q: Can I use an updated part number if my model year is older?
- A: It depends. Updated part numbers often replace older ones; verify compatibility with your exact model and year in the listing or consult a marine technician.
- Q: Should I replace the entire exhaust elbow when replacing a gasket?
- A: If the elbow shows wear or damage, using a repair kit that includes elbows and gaskets can be cost-effective, but a simple gasket swap is sufficient when seals are intact.
- Q: Are these gaskets suitable for saltwater use?
- A: Yes, but ensure the gasket materials are corrosion-resistant and consider marine-grade sealants where recommended by the manufacturer.
- Q: Do these products include all required hardware?
- A: Some listings include related components like clamps or hoses; others are gasket-only. Confirm the contents before purchase.
