When you need a MerCruiser 5.0 Thru Hull Exhaust Kit (or the 5.7 or 6.2 kits) to help overhaul your engine, choose PowerBoatSupply.com for the highest-quality replacement parts. Whether you're an experienced marine mechanic or a new boat owner just learning the ropes, you know a boat’s exhaust is a key system that has to function properly to vent spent gasses while keeping water from seeping into the engine. We carry all of the individual MerCruiser 5.0, 5.7, and 6.2 exhaust parts you need to completely refurbish your exhaust system, but when you need to replace the entire exhaust, it’s usually better to buy a kit.
MerCruiser 5.0 Thru Hull Exhaust Kit
It’s recommended that you inspect your boat’s exhaust every season and replace parts when they are worn, or after 5 years of use in saltwater applications. Freshwater exhausts might have a longer lifespan, but it’s still best to err on the side of caution. Exhaust manifolds are one of the most key components of any exhaust system, which is why MerCruiser 5.0, 5.7, and 6.2 exhaust manifolds are always best-selling parts. As we mentioned above, it’s often best to buy a MerCruiser 5.7 thru hull exhaust kit (or whatever kit fits your engine) and replace the whole system, riser and gaskets included.
Thru Hull Exhaust Kit MerCruiser 5.7 Replacement
Another integral part of the exhaust system is the riser. This is why you’ll find MerCruiser 5.0, 5.7, and 6.2 riser elbows in every exhaust kit. The riser transfers gasses from the manifold to the rest of the exhaust and needs to be positioned high enough above the waterline to keep water from back-flowing into the system. It’s also imperative that the gaskets between the risers and the manifolds are in good condition. Just a little leak could lead to a giant headache that keeps your boat off the water.
