The Sea-Doo GTX, RX, GSX, LTD, and LRV models produced between 1998 and 2002 with the 951 carburetor system and using NgK (Nickel-Gas-Kimax) spark plugs are popular choices for personal watercraft enthusiasts. Here are some pros and cons of buying this model:

1. Power: These models come with powerful engines that deliver impressive performance. The 1998-2002 Sea-Doo GTX, RX, GSX, LTD, and LRV models feature the Rotax 1100 ACE engine, which provides a thrilling riding experience.

2. Durability: These Sea-Doos are known for their durability and reliability. The 951 carburetor system and NgK spark plugs are proven components that have stood the test of time.

3. Affordability: Compared to newer models, these Sea-Doos are relatively affordable. You can find good deals on used models, making them an attractive option for budget-conscious buyers.

4. Customizability: These models offer a wide range of customization options. You can add aftermarket parts and accessories to personalize your watercraft and enhance its performance.

1. Fuel Efficiency: The 1100 ACE engine is a powerhouse but it's not very fuel-efficient. You can expect to go through a significant amount of gas during long rides.

2. Maintenance: Older models require more maintenance than newer ones. The 951 carburetor system can be finicky, and you may need to adjust the jets or replace worn parts from time to time.

3. Safety: Older models may not have the same safety features as newer ones. For example, they may not have a reverse warning system or a kill switch lanyard.

4. Repairs: Repairing older models can be more challenging and expensive than repairing newer ones. You may need to source hard-to-find parts or pay a premium for specialized labor.

The 1998-2002 Sea-Doo GTX, RX, GSX, LTD, and LRV models with the 951 carburetor system and NgK spark plugs offer a thrilling riding experience, durability, and customizability, but they come with some drawbacks such as fuel inefficiency, maintenance requirements, safety concerns, and repair costs.

If you're looking for an affordable, powerful, and customizable personal watercraft, this model may be a good choice for you. However, be prepared for the additional maintenance requirements and potential repair costs. If you prioritize safety features, fuel efficiency, or ease of use, you may want to consider a newer model instead.
