Best Use Case
This filter disc is the correct service replacement for Mercury and MerCruiser engines equipped with the Gen III Cool Fuel module.

Parts Desk Insights
This is a routine maintenance item that’s easy to overlook — many customers don’t realize the Gen III Cool Fuel module has a serviceable internal filter disc until they experience a fuel delivery issue. It’s worth mentioning proactively to any customer servicing a Mercury or MerCruiser inboard or sterndrive engine equipped with this module. When a customer orders this disc, ask whether they also need the housing O-rings — it’s good practice to replace them at the same time. For other Mercury/MerCruiser engine maintenance parts, see the Quicksilver Power Trim Anode 818298Q1 and Quicksilver Anodic Plate 76214Q5 for corrosion protection, and the PCM / Crusader Fuel Filter Element 47047 for PCM-powered vessels.
