### **Pros and Cons of Buying Motorsport Gaskets (Part #701575998128, M-G 33116) for a Mikuni 44mm Carburetor on Sea-Doo 717/720/787/800**
#### **Pros:**1. **OEM Compatibility** The gasket is designed specifically for Mikuni 44mm carburetors, ensuring a proper fit on Sea-Doo models 717, 720, 787, and 800. This reduces the risk of leaks or improper sealing compared to aftermarket alternatives that may not match perfectly.
2. **High-Quality Materials** Motorsport gaskets are typically made from durable materials like silicone or rubber with reinforced construction, providing better heat and vibration resistance than standard OEM gaskets. This can improve longevity, especially under high-performance conditions.
3. **Enhanced Sealing Performance** A well-fitted gasket minimizes air and fuel leaks, improving throttle response and fuel efficiency. This is particularly useful if you ve modified your carburetor or engine for better performance.
4. **Ease of Installation** The gasket is pre-cut and designed for straightforward installation, reducing the risk of mistakes during assembly. This is beneficial for DIYers who may not have extensive mechanical experience.
5. **Compatibility with Upgrades** If you ve upgraded your carburetor or engine components (e.g., performance jets, larger throttle bodies), a high-quality gasket ensures that modifications work as intended without leaks compromising performance.
6. **Long-Term Reliability** Motorsport gaskets are often built to withstand higher stress levels, making them a good choice if you plan to keep your Sea-Doo running for years with occasional performance tweaks.

#### **Cons:**1. **Cost** Motorsport gaskets are generally more expensive than standard OEM replacements. While the price difference may be minimal for a single gasket, it could add up if you need multiple parts or if you re replacing gaskets frequently due to wear.
2. **Potential Overkill for Stock Applications** If you re running your Sea-Doo in stock or near-stock condition without aggressive modifications, a high-end Motorsport gasket may not offer significant advantages over a standard OEM gasket. The extra cost may not be justified unless you re actively tuning or pushing the engine.
3. **Availability and Sourcing** Motorsport gaskets may not be as widely available as OEM parts, especially if you re purchasing from a specialty supplier. You might need to order online or from a performance parts dealer, which could introduce delays if you re in a hurry.
4. **Installation Risks** While the gasket is designed for easy installation, improper handling (e.g., stretching, misalignment, or using the wrong adhesive) could still lead to leaks. If you re not careful, you might end up with the same issues you were trying to fix.
5. **Compatibility with Aftermarket Carburetors** If you ve installed an aftermarket Mikuni 44mm carburetor (e.g., from a different manufacturer or a remanufactured unit), there s a slight chance the gasket dimensions might not match perfectly. Always verify compatibility before purchasing.
6. **Durability Under Extreme Conditions** While Motorsport gaskets are robust, they are not indestructible. In extreme environments (e.g., prolonged high RPM, extreme temperatures, or aggressive tuning), even high-quality gaskets can degrade faster than expected, requiring more frequent replacements.

### **Conclusion:**The **Motorsport Gaskets (701575998128, M-G 33116)** for your Mikuni 44mm carburetor on a Sea-Doo 717/720/787/800 is a solid choice if you prioritize **reliability, performance, and longevity**, especially if you ve modified your engine or carburetor. The gasket s high-quality construction and precise fit make it a worthwhile investment for those who demand better sealing and durability.
However, if you re running your Sea-Doo in **stock or lightly modified conditions** and are on a tight budget, a **standard OEM gasket** (if available) might suffice without the extra cost. The decision ultimately depends on your **performance goals, budget, and how aggressively you plan to use the vehicle**.

### **Recommendation:** - **Buy the Motorsport gasket if:**- You ve modified your carburetor or engine (e.g., upgraded jets, throttle body, or performance tuning).
- You want to minimize leaks and ensure long-term reliability under higher stress.
- You re willing to pay a premium for high-quality parts that reduce maintenance hassles.
- **Consider an OEM or budget gasket if:**- Your Sea-Doo is running stock or with minimal modifications.
- You re looking to save money without sacrificing performance significantly.
- You can easily source a compatible OEM replacement (though these may be harder to find for older Sea-Doo models).
**Final Verdict:** For most performance-oriented Sea-Doo owners, the **Motorsport gasket is the better long-term choice**, especially if you plan to keep the engine tuned or modified. If you re unsure, test-fit the gasket before committing to ensure it aligns perfectly with your carburetor setup. Always pair it with a **clean installation** (no debris, proper gasket surface prep) to maximize its effectiveness.
