Review WSM Starter Relay For Yamaha Wavejammer Jet Ski for YAMAHA 1989–1990

The WSM 18143-W348806-53 starter relay is a crucial component for starting the engine on 1989 and 1990 Yamaha WJ500 WaveJammer jet skis. This high-quality starter relay is designed specifically for these models, ensuring a reliable and efficient starting process.

The WSM starter relay is engineered with a robust construction, featuring a heavy-duty housing that can withstand the rigors of frequent use in a marine environment. It is sealed against moisture and other harsh elements, providing superior protection against corrosion and damage.

This starter relay is designed to handle the high current demands required to start the engine, with a contact rating of 15A at 12V DC. It features a gold-plated contact surface, which ensures a strong and reliable electrical connection, reducing the risk of arcing and sparking that can cause damage to other components.

The WSM starter relay is also easy to install, with a simple plug-and-play design that connects directly to the jet ski's wiring harness. It is compatible with the original equipment manufacturer (OEM) wiring, making it a straightforward and hassle-free replacement for the factory-installed relay.

One notable feature of this starter relay is its built-in diode, which provides reverse polarity protection. This means that the relay can prevent damage caused by backfiring or reverse current flow, which can be common in marine applications.

In summary, the WSM 18143-W348806-53 starter relay is a must-have for any Yamaha WJ500 WaveJammer jet ski owner. Its robust construction, reliable performance, and easy installation make it an essential upgrade for ensuring the reliable and efficient operation of your jet ski's engine starting system.

The WSM 18143-W348806-53 starter relay is a commonly used replacement part for the 1989-1990 Yamaha WaveRunner WJ500 jet ski's starter system. Here are some pros and cons to consider before making a purchase:

1. Availability: This particular relay is widely available from various automotive parts retailers both online and offline, ensuring easy accessibility for most users.

2. Compatibility: It is specifically designed to fit and function in the Yamaha WJ500's electrical system, reducing the chances of compatibility issues.

3. Replacement: If your existing starter relay has failed, this part offers a viable solution for getting your jet ski back up and running.

4. Cost-effective: In comparison to the cost of replacing the entire starter system, a new relay can be a more affordable repair option.

1. DIY installation: Installing the relay yourself may require some technical knowledge and skills. Consulting a professional mechanic could save time and potential frustration.

2. Potential for additional issues: A faulty starter relay could be a symptom of a larger electrical issue within the jet ski. Replacing the relay alone may not solve the problem if there are other underlying electrical issues.

The WSM 18143-W348806-53 starter relay is a reliable replacement part for the Yamaha WJ500's starter system. However, it's essential to consider the potential for additional electrical issues and the need for professional installation. If you feel confident in your ability to install the relay yourself and suspect that the issue is solely with the starter relay, then this part may be an excellent investment. Otherwise, it might be worth considering a more extensive diagnostic check to identify any underlying electrical problems.

Before making a purchase, consider reviewing your jet ski's service history and assessing your comfort level with DIY repairs. If you're unsure about installing the relay yourself or suspect that there may be other electrical issues, it's best to consult a professional mechanic for advice. Ultimately, the decision to purchase the WSM 18143-W348806-53 starter relay depends on your personal circumstances and the complexity of the issue at hand.
