Frequently asked questions
What fuel filter fits a Mercury 60 HP (60 hp)?
The Mercury 60 HP uses the fuel filter sold as 18-7748, plus its OEM and aftermarket cross-references (17 compatible numbers are listed above). Confirm the number against your engine's model code and year plate before ordering.
How often should I replace the fuel filter on a Mercury 60 HP?
Replace the fuel filter once a season or per the service manual — and sooner after a batch of dirty fuel or water in the separator.
What are the symptoms of a clogged fuel filter on a Mercury 60 HP?
Hard starting, hesitation or surging under load, stalling at higher throttle and a general loss of power. The engine typically runs fine at idle and starves when fuel demand rises.
Do I need to bleed or prime the fuel system afterwards?
On diesel engines, yes — air must be bled from the fuel system after the filter change, and the video shows the procedure. On petrol outboards, squeeze the primer bulb firm before starting.
How long does a fuel filter change take on a Mercury 60 HP?
Usually 30-60 minutes including priming or bleeding — a straightforward DIY job with basic tools.
