<h2>Introduction</h2>

When it comes to marine insurance claims in New Zealand, one common issue is boats being damaged due to incorrect fuel or water ingress. The consequences can be severe, including voiding of claims if the engine is run after a mishap.

<h2>Why Running the Engine Can Void a Claim</h2>

NZ marine insurers have clear guidelines on what constitutes valid claims and when running the engine could jeopardize your coverage. Here’s an overview of how they handle these situations:

<ul> <li><strong>Misfueling:</strong> If you accidentally put the wrong type of fuel in your boat, such as diesel in a petrol outboard motor or vice versa, it can lead to serious damage. Running the engine after this misfueling could void your insurance claim.</li> <li><strong>Water Damage:</strong> When water enters the fuel system through contaminated fuel or other means, it can cause significant damage. If you attempt to run the engine with water in the system, insurers may not cover the repairs.</li> </ul> <h2>What to Do Right Now</h2>

If you suspect your boat has been damaged due to misfueling or water ingress:

<ul> <li><strong>Do Not Run the Engine:</strong> This is always the #1 rule. Running the engine can cause further damage and void your insurance claim.</li> <li><strong>Contact Your Insurer:</strong> Reach out to your marine insurer immediately to report the incident. They will guide you through the process of filing a claim and may require documentation such as photos, witness statements, or a professional assessment.</li> <li><strong>Seek Professional Assistance:</strong> If water has entered the fuel system, it’s crucial to have a certified marine technician perform manufacturer-spec fuel system recovery at the workshop. This can prevent further damage and ensure your insurance coverage remains valid.</li> </ul> <h2>Conclusion</h2>

Handling boat misfueling and water-damage claims requires careful attention to detail and adherence to specific guidelines set by NZ marine insurers. By following these steps, you can help maintain your insurance coverage and avoid unnecessary costs or complications.
