Engine & Model Compatibility
The catalog occurrences below identify this filter assembly by reference number in the listed Mercury four-stroke fuel-pump diagrams. The catalog records provide engine model, horsepower, stroke, and serial-number conditions, but do not establish a universal fit for all engines in a horsepower range.
| Brand | Model | Rated HP | Stroke | Serial Number Condition | Catalog Reference |
|---|---|---|---|---|---|
| Mercury | 75 Four-Stroke Bodensee | 75 | 4-Stroke | 0G960500 through 0T800999 | 35-881538T02 |

Always compare the original filter, manufacturer reference number, engine model, and complete serial-number range. A horsepower match by itself is not sufficient to confirm compatibility.

Troubleshooting & FAQ
How do I confirm this filter fits my engine?
Compare your original reference number with 881538T1, 881538T02, 35-881538T1, or 35-881538T02, then verify the engine model, four-stroke configuration, and complete serial-number range in the compatibility table. If any condition differs, consult the engine service documentation before ordering.
What are common signs that a fuel filter may need replacement?
Restricted fuel flow can contribute to hard starting, hesitation, stalling, or loss of power. These symptoms can have other causes, so inspect the complete fuel system and follow the manufacturer’s diagnostic procedure.
Are 35-881538T1 and 35-881538T02 the same number?
Both numbers are listed as references for this product, and 35-881538T02 is the reference identified in the catalog occurrences. Confirm the number and serial-number application against your engine documentation rather than relying on the number alone.
Does this product include a fuel pump or installation kit?
No. This listing is for one fuel filter assembly only. A fuel pump, hoses, clamps, and other installation parts are not specified as included.
Is this an OEM part?
This listing is for a replacement fuel filter assembly. The listed Mercury numbers are manufacturer reference numbers used for identification; this product should not be treated as a genuine Mercury-branded part unless the packaging explicitly states otherwise.
How much is shipping?
Available shipping methods, delivery estimates, and charges are shown at checkout based on the destination and selected service.
What is the warranty and return policy?
Warranty coverage and return eligibility are governed by the seller’s current policies. Review the applicable policy before installation, and retain the order information and original packaging.
