First Impressions of Sierra International 187802 Fuel Filter
The Sierra International 187802 Fuel Filter promises to be a reliable solution for maintaining clean fuel in marine engines. Sierra, a trusted name in marine parts, offers this filter as a direct replacement for several popular brands, including Mercury, Fram, and Wix. The compatibility and stated 75-micron rating immediately caught my attention as someone who values preventive maintenance in harsh marine environments.
I had been struggling with recurring carburetor issues on my older outboard, and suspected contaminated fuel was the culprit. Many generic fuel filters just don’t offer the filtration level needed for modern engines. I specifically needed a filter that could handle the demands of potentially ethanol-blended fuels and prevent water intrusion.
Upon receiving the Sierra International 187802 Fuel Filter, I was pleased with its solid construction. It felt robust and well-sealed, reassuring me that it could withstand the rigors of marine use. Compared to a cheaper, universal fuel filter I had previously tried, the Sierra filter felt significantly more substantial.
While I also considered a Mercury OEM filter, the Sierra option, with its multiple cross-references and competitive price of $10.99, made it the more practical choice. My initial impression was positive, and I was eager to put it to the test and see if it could finally resolve my fuel contamination issues.
Real-World Testing: Putting Sierra International 187802 Fuel Filter to the Test
First Use Experience
I installed the Sierra International 187802 Fuel Filter on my 1980s Johnson 70HP outboard motor powering my small fishing boat. The installation process was straightforward, requiring only basic tools and about 15 minutes of my time. The included viton seal created a secure, leak-free connection with the existing fuel filter assembly.
My first trip out was a near-shore fishing excursion, facing choppy seas and occasional splashes. The engine ran smoothly and consistently throughout the day, with no signs of fuel starvation or hesitation. Previously, I would have experienced intermittent sputtering and rough idling with the old, less effective filter.
There were no immediate issues or surprises after the first use, which was a promising start. The engine’s improved performance was immediately noticeable, increasing my confidence in the Sierra International 187802 Fuel Filter.
Extended Use & Reliability
After several weeks of regular use, the Sierra International 187802 Fuel Filter continues to perform admirably. I’ve logged over 50 hours on the water, including a few longer trips further offshore. I’ve observed no degradation in engine performance or any signs of fuel-related problems.
The filter body shows no signs of wear or damage, despite exposure to saltwater and engine heat. I have visually inspected the fuel bowl several times and noticed a marked decrease in sediment and debris compared to before installing the Sierra filter.
Maintenance is simple: just inspect the filter regularly and replace it annually, or sooner if fuel contamination is suspected. Based on my positive experience so far, the Sierra International 187802 Fuel Filter significantly outperforms the generic filters I used in the past, offering far greater reliability and peace of mind.
Breaking Down the Features of Sierra International 187802 Fuel Filter
Specifications
The Sierra International 187802 Fuel Filter is designed as a direct replacement for various marine fuel filter assemblies. It boasts a 75-micron filtration rating, crucial for removing fine particles that can damage carburetors and fuel injectors. The filter is designed to be used with the Sierra 18-7113-9 O-Ring.
The filter is designed for Mercury under-cowl fuel filter assemblies with a screw-on bowl. The vital statistics allow it to be interchangeable with Fram P8263, Mercury 35-87946Q4, 35-87946Q3, 35-87946A3, and Wix 33398 fuel filters. The included viton seal resists degradation from ethanol and other fuel additives.
Performance & Functionality
The Sierra International 187802 Fuel Filter excels at removing contaminants from the fuel supply, ensuring smooth and reliable engine operation. Its 75-micron rating strikes a good balance between filtration efficiency and fuel flow. A finer micron rating might restrict flow, while a coarser one wouldn’t adequately protect the engine.
The filter’s direct replacement design simplifies installation, minimizing downtime and hassle. The Viton seal provides a secure and durable seal, preventing leaks and maintaining fuel pressure. Its performance has met and exceeded my expectations, effectively resolving the fuel contamination issues I was experiencing.
Design & Ergonomics
The Sierra International 187802 Fuel Filter features a robust and well-engineered design. The materials used appear to be of high quality, ensuring durability in the harsh marine environment. While the filter itself is not held in the hand, its ease of installation and secure fit contribute to a user-friendly experience.

Durability & Maintenance
The Sierra International 187802 Fuel Filter is built to withstand the rigors of marine use. Its durable construction and corrosion-resistant materials ensure a long service life. Regular inspection and annual replacement are recommended to maintain optimal performance and prevent fuel-related problems.
Maintenance involves simply unscrewing the old filter, cleaning the fuel bowl, and installing the new filter with a new O-ring. The simplicity of maintenance adds to the overall appeal of this product.
Accessories and Customization Options
The Sierra International 187802 Fuel Filter does not offer many customization options, as it is primarily a direct replacement part. It requires the Sierra 18-7113-9 O-Ring. However, its compatibility with various fuel filter assemblies allows for some flexibility in choosing the specific type of bowl or housing used.
It’s also compatible with any associated fuel lines and fittings appropriate for the fuel filter assembly it integrates with. There are no available options for upgrading to a different micron rating within the Sierra 187802 model.
