Indmar Marine V-Band Clamp – Catalyst Exhaust | Part #735020

Secure your catalyst exhaust system with this genuine Indmar V-band clamp designed specifically for Indmar catalyst exhaust applications. The V-band clamp provides a strong, even clamping force around the full circumference of the exhaust joint — delivering a leak-free seal that withstands the heat, pressure, and vibration of continuous marine exhaust operation.

Compatible with: Indmar marine engines with catalyst exhaust systems fitted to Malibu, Moomba, Supra, and Tige boats. Contact us to verify fitment before ordering.

Signs your V-band clamp needs replacing:

• Exhaust gas smell or smoke at the catalyst exhaust joint
• Visible exhaust soot or staining around the clamp area
• Clamp body cracked, corroded, or distorted
• Fastener stripped or unable to achieve correct clamp tension
• Exhaust joint movement or misalignment visible under inspection

Pro tip: When servicing your catalyst exhaust system always check V-band clamp condition before reassembly. A clamp that has been removed and refitted multiple times may have lost clamping tension — replace it at the same time as your exhaust gaskets for a complete leak-free exhaust service.
