7.4 454 & 502 Y Pipe Parts
NuWave Marine carries all the MerCruiser 7.4-454-502 Y-pipe parts you need to refurbish or replace your MerCruiser exhaust. Whether you're new to marine engine maintenance, or a veteran mechanic who has seen it all, you know that basic, routine maintenance is key to keeping your boat's motor healthy. We recommend you inspect your entire exhaust system every year and replace it when you notice wear, or after 5 years, whichever happens first. Should you need new parts, this collection of MerCruiser 7.4-454-502 exhaust parts will have you covered. Select a MerCruiser 454 Y pipe, and make sure you have the part you need for the job.
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 NuWave Marine. 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.
