How to Flush a Jet Ski: A Comprehensive Guide

Jet skis are a popular choice for water sports enthusiasts, offering thrilling rides and unforgettable experiences on the water. However, like any other watercraft, proper maintenance is essential to keep your jet ski running smoothly and prolong its lifespan. One important maintenance task is flushing the engine after each ride, to remove any salt or debris that may have entered the cooling system. In this article, we will guide you through the process of flushing a jet ski, ensuring that it remains in top condition for years to come.

To flush a jet ski, you will need a few basic tools and supplies, including a hose with a nozzle attachment, a flush kit (if not built-in), and a clean water source. Here’s a step-by-step guide to help you through the process:

1. Locate the water intake on your jet ski. It is usually found at the rear of the craft, underneath the seat or near the pump area.

2. Attach the hose to the water intake using the flush kit or nozzle attachment. Ensure a secure connection to prevent leaks.

3. Turn on the water source, allowing a steady flow of water to enter the cooling system.

4. Start the jet ski’s engine and let it run at idle speed for about 5 minutes. This will allow the water to flush through the cooling system, removing any salt or debris.

5. Monitor the water temperature gauge to ensure it remains within the normal operating range. Flushing with cold water can cause damage to the engine, so be cautious.
