FAQ
What engines does this oil change kit fit?
This kit fits many compatible MerCruiser inline 4-cylinder,
inline 6-cylinder, V6, and V8 sterndrive and inboard marine engines.
Will this kit work for 7.4L, 8.1L, and 8.2L MerCruiser engines?
Yes, but these larger displacement engines typically require
one to two additional quarts of Mercury SAE 25W40 engine oil
that is not included in this kit.
What does FC-W(CAT) Certified mean?
FC-W(CAT) certification indicates the oil meets marine industry standards
for corrosion protection, lubrication performance, and marine engine durability,
including catalyst-compatible applications.
Does this kit include an oil filter?
Yes. This kit includes a premium Mercury oil filter for compatible
MerCruiser marine engine applications.
Can I perform this oil change service myself?
Yes. Many boat owners perform routine oil and filter maintenance themselves
using basic hand tools and the proper service parts. Always follow your
engine manufacturer’s service procedures and verify proper oil capacity
before operation.
If you do not feel comfortable performing maintenance yourself, a Mercury-certified marine technician can typically complete this service quickly and help verify your engine is operating properly.
