Would have been 5 stars but....

Would have been 5 stars but, I did not receive a promotional sticker with my $2000 drive unit. Just kidding, everything was great!

Gasket Exhaust Elbow 3 Hole | Crusader 96108

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.

Piranha Propeller

I couldn’t find a Piranha propeller dealer near me in Canada but found Macomb Marine Parts who could deliver to me. The order process was smooth and I was even contacted via email for clarification regarding blade shape and they were very helpful in choosing the best shape for my purposes.
I can’t comment on the prop’s performance yet as we haven’t had the boat in the water yet.

Upgrade Your Boat Engine with Premium Spark Plugs at Macomb Marine Parts!

Upgrade Your Boat Performance with Marine Spark Plugs

Every boater knows the importance of a reliable engine. Your engine depends on a strong spark to start and run smoothly. High-quality marine spark plugs are essential for this process. At Macomb Marine Parts, we provide a wide selection of top-tier plugs. Whether you need better fuel economy or smoother idling, we have the right fit. Our inventory includes trusted brands like NGK, AC Delco, and Champion. Therefore, you can shop with confidence knowing your vessel is in good hands.

Why Quality Spark Plugs Matter

Standard spark plugs often fail in harsh marine environments. Saltwater and humidity can cause rapid corrosion. Consequently, your engine may misfire or lose power. Marine-grade spark plugs are designed specifically to resist these elements. They feature special coatings and robust materials to ensure longevity. By choosing the right parts, you prevent unexpected breakdowns on the water. Furthermore, fresh plugs help your engine burn fuel more efficiently. This leads to lower costs and more time spent enjoying the waves.

Find the Right Brand for Your Engine

We understand that every boat has unique requirements. Because of this, we stock a massive variety of ignition components. You might be looking for NGK V-Power plugs for enhanced performance. Alternatively, you may prefer AC Delco Iridium plugs for their long-lasting durability. We also carry specialized kits for brands like Crusader and Volvo Penta. Selecting the correct heat range is vital for engine health. If you are unsure about compatibility, our team is here to help. We make it easy to find exactly what your motor needs.

Signs You Need New Marine Spark Plugs

How do you know when it is time for a change? First, look for signs of engine hesitation during startup. Second, notice if your boat is consuming more fuel than usual. Rough idling is another common indicator of fouled plugs. If you see carbon buildup or physical damage, replace them immediately. Regular maintenance is the best way to avoid expensive repairs later. In fact, most experts suggest checking your plugs at least once per season. Keeping a spare set on board is also a very smart habit.
