Maintain a clean and compliant cooling and emission system with this genuine Indmar 1/2 inch pre-formed emission hose. Precision formed to the exact OEM shape for a perfect fit straight out of the box — no cutting, bending, or adapting required. Built specifically for Indmar marine engines where emission system integrity is essential for both performance and environmental compliance.

Compatible with: Indmar marine engines fitted to Malibu, Moomba, Supra, and Tige boats.

What does the emission hose do?
The emission hose routes vapours and gases away from the engine as part of the emissions control system. A cracked or deteriorated emission hose can cause:

• Fuel or coolant vapours entering the engine bay
• Failed emissions compliance checks
• Rough running or poor idle
• Unpleasant fumes in and around the boat

A small, inexpensive part that's often overlooked — until it causes a bigger problem.

When should you replace it?
Replace your emission hose if you notice:

• Visible cracking, hardening, or brittleness
• Fuel or coolant smell around the engine bay
• Soft spots or swelling along the hose body
• Any signs of leaking at the hose connections

Pro tip: When servicing your emission system, inspect all related hoses at the same time. Replacing one worn hose now is far cheaper than an engine bay full of fumes or a compliance issue later.
