❓ FAQ
Every 100 engine hours or once per season, whichever comes first. Shorten the interval if the clear bowl shows heavy water after each trip, or if the engine stumbles at high load.
It fits heads that accept a 3/8 in NPT port and an 11/16-16 UNC element thread — the pattern shared by Mercury, Yamaha, Suzuki and Honda outboard separators that take S3213 or 35-809097 elements. Compare both threads before ordering.
No. The box contains one 10 micron element and one clear nylon bowl. The head and bracket already bolted to your transom are reused, which is why this kit costs less than a complete separator assembly.
10 micron is the common rating for petrol outboards and is what Mercury 35-809097 and Racor S3213 elements use. Finer 2 micron elements belong on fuel-injection diesel systems and load up faster on petrol.
Yes, if the old bowl is still clear, uncracked and the drain screw seals. Replace the bowl when it has yellowed to the point that water is hard to see, or when the thread or drain screw is damaged.

Description
Product Overview
The S3213 marine fuel water separator kit pairs a 10 micron spin-on element with a reusable clear nylon bowl, so one box covers both halves of a routine outboard filter change: the element that wears out and the bowl that yellows or cracks over time. It fits filter heads with a 3/8 in NPT port and an 11/16-16 UNC element thread, and replaces Mercury 35-809097, Racor S3213 and Sierra 18-7919 style elements. The mounting head and bracket are not included.
