Replace your boat’s old exhaust system with MerCruiser 4.3 exhaust kits from PowerBoatSupply.com, and make sure your engine is protected from leaks. Marine motors are built tough, but if there’s one thing they can’t handle, it’s water in places it shouldn’t be. The exhaust system is a main area where wear and tear can lead to leaks that allow water to seep into your engine. We recommend inspecting your MerCruiser exhaust every year, and replacing it every 5 years if you have a saltwater boat. Though it can be tempting to simply replace an individual part that seems to be worn out, it’s worth considering that if one part has wear and tear, the other components probably do, too.
MerCruiser 4.3 Exhaust Manifold Conversion Kit
Upgrading some MerCruiser 4.3 exhaust systems will require a conversion kit. At PowerBoatSupply.com, we have 1-piece to 2-piece conversion kits that will make the job easy.
MerCruiser 4.3 Exhaust Manifold Kit
The standard exhaust manifold includes all the components you’ll need to completely redo your boat’s exhaust. Kits come complete with exhaust manifolds that gather the spent gasses from your engine’s pistons, and MerCruiser 4.3 riser elbows that vent and cool your exhaust. Kits also include gaskets to form a tight seal between parts and the bolts to hold everything in place. Our 4.3 MerCruiser thru hull exhaust kit will help you keep your engine performing at its peak. Choose from wet joint and dry joint 4.3 liter exhaust kits.
Invest in Quality Replacement Parts
As stated above, the exhaust system is a critical area where water can seep into your boat’s motor. It makes sense to invest in quality replacement parts when servicing your exhaust. After all, choosing premium parts here can save you from headaches down the line. With four decades of experience in the marine engine repair field, we never settle for anything less than the best quality engine components. PowerBoatSupply.com only carries OEM parts and parts from trusted brands like Sierra. If we wouldn’t use them on our boat, we wouldn’t sell them to you.
