MerCruiser 7.4 Y Pipe

Y-pipes are designed to collect the spent exhaust from both manifolds and direct them towards the transom. In short, they’re needed to direct the exhaust from your MerCruiser to a single point. For example, a MerCruiser 502 Y pipe will connect both exhaust manifolds and funnel the spent gasses to a single point.

MerCruiser Exhaust Y Pipe Gasket

Gaskets are essential for forming a tight seal, especially where your Y-pipe meets the riser elbows. Depending on your boat’s design, your MerCruiser Y pipe and riser elbow might not perfectly line up. If this is the case, you can use spacer kits from PowerBoatSupply.com. They're designed to elevate the riser elbows when needed, and will help your exhaust system fit together perfectly. With new parts and expert assembly, your exhaust system will effectively vent gasses and cool your engine, without leaking water into places where it can do serious damage.
