Quality Marine Engine & Drive Parts
Since 2006
Let customers speak for us
from 99 reviewsI like shopping with Macombmarineparts! I did not see an exact replacement so I contacted support and they found it and sent me a picture just to be sure.
These work awesome I run a river that is very shallow and rocky and things happen. These replacement. Blades are better than sliced bread.
Very helpful fast delivery, accurate part numbers
This place was amazing very helpful courteous fast delivery exactly what I need
Changed the remote control and cables on my bass boat from GEN 1 to GEN 11, the new Gen 11 cables fit but with very little adjust thread on the rod. The old Gen1 cables has a lot more adjustment thread. Just put them on my boat today, started and worked good in my driveway, I will get to to lake soon to see how everything does.
Easy ordering and fast shipping
Nice quality part, and fast shipping
Thanks, though the Bosch unit you sent did have a 5th blade and no tab for a securing ****.
Great Stuff Use it Every Winter
Would have been 5 stars but, I did not receive a promotional sticker with my $2000 drive unit. Just kidding, everything was great!
Fast track to Germany…
Ordered aftermarket power pack for my 55hp Johnson. Received email and text offering OEM part at aftermarket price. Absolutely great! Thanks!!!
Great company to work with!
Ordered a Piranha Propellers Complete A-Series 4 Blade Propeller from Macomb Marine Parts and even though we’re international, it arrived in just over a week — fast and reliable service. The propeller itself is a real lifesaver. We had the same model before, and after hitting a rock that damaged two blades, we were able to swap them right on the water and make it back to the marina without issue — something you simply can’t do with a regular aluminum prop. For peace of mind we decided to buy a complete new set (hub and blades) since an impact like that could cause hidden damage, but the system really proved its worth.

Maximize Performance with Quality Marine Exhaust Systems
Marine Exhaust Systems & Parts - A healthy engine relies on an efficient marine exhaust system. Consequently, choosing the right parts is vital for your boat's longevity. These systems work hard to remove hot gases and manage cooling water. Because marine environments are highly corrosive, these components require regular maintenance. At Macomb Marine Parts, we offer a massive selection of high-quality exhaust components. Therefore, you can find everything from manifolds to risers in one convenient place.
Why Your Boat Engine Needs a Robust Exhaust
First of all, the exhaust system is responsible for protecting your engine block. It ensures that cooling water does not leak back into the cylinders. If water enters the engine, it can cause immediate and permanent failure. In addition, a well-designed system reduces back pressure for better fuel efficiency. Since high-performance engines generate intense heat, the exhaust must be durable. Moreover, our parts feature precision castings to ensure a perfect fit. As a result, your boat will run smoother and stay reliable for years.
Essential Components of an Exhaust System
To maintain your boat, you must understand the key parts of the system. For instance, the exhaust manifold collects gases directly from the engine cylinders. Afterward, the exhaust riser or elbow directs those gases safely overboard. These parts must work together seamlessly to prevent leaks and overheating. Fortunately, we stock individual parts and complete kits for all major brands. Whether you have a small 3.0L engine or a big block V8, we have the solution. Thus, you can easily find the exact match for your specific marine application.
Signs of Wear and When to Replace Parts
Identifying exhaust issues early can save you thousands of dollars in repairs. For example, look for rust streaks or "weeping" at the gasket lines. Also, listen for any unusual tapping sounds that might indicate an exhaust leak. Since corrosion often starts on the inside, periodic removal and inspection are wise. Furthermore, if you notice your engine running hotter than normal, a blockage may exist. Consequently, most experts suggest replacing cast iron components every five years in saltwater. Therefore, keeping a close eye on your system is the best way to ensure safety.
Shop the Best Brands at Macomb Marine Parts
We take pride in offering the most trusted names in the marine industry. Specifically, our inventory includes parts for Mercruiser, Volvo Penta, and Crusader. We provide both OEM replacements and high-quality aftermarket alternatives to fit your budget. Because we focus on customer satisfaction, our team is ready to help you find the right part number. Moreover, our fast shipping ensures you spend more time on the water and less time waiting. Ultimately, macombmarineparts.com is your one-stop shop for all your marine exhaust needs.
Frequently Asked Questions
How often should I replace my marine exhaust manifold?
In saltwater environments, you should inspect manifolds every three years. Generally, they require full replacement every five to seven years to prevent internal leaks.
What causes a marine exhaust system to fail?
The primary cause is internal corrosion from saltwater and heat cycles. Over time, the metal thins and allows water to seep into the exhaust ports.
Are gaskets included with the exhaust kits?
Yes, most of our complete kits include the necessary mounting gaskets. However, always check the product description for specific details on what is included.
Can a bad exhaust system reduce my boat's speed?
Absolutely, because excessive back pressure limits engine power. A fresh, clear exhaust system allows the engine to breathe and perform at its peak.
