Sea-Doo 300hp intake manifold reinforcement

An intake manifold strengthener, also known as a girdle or brace, adds support around the plastic manifold seam. On supercharged Sea-Doo 300 horsepower engines, boost pressure can stress this joint and cause splitting or a boost leak. Bracing helps reduce movement at the seam, particularly on tuned engines running higher boost. A split or leaking manifold should be replaced before fitting a brace.

Installation

The clamp-on design does not require drilling or grinding of the stock manifold.

Fitment

Selected supercharged Sea-Doo 4-TEC applications. Match the manifold shape and part number before ordering, particularly on a modified ski or a craft with a replacement engine or intake. Contact South Quay Leisure with your model and year for help selecting the correct support.
