Engine Compatibility
The strongest supportable fitment for 75411 is MerCruiser 470 (2 BBL.) Mercury 224 I/L4 across 1976-1984 serial ranges and 470 MIE Mercury 224 I/L4 in current listed ranges. Current Mercury dealer where-used references specifically show it on 470 (2 BBL.) Mercury 224 I/L4 1976-1979, 1980-1982, 1983-1984, and 470 MIE Mercury 224 I/L4 1980-1981 applications.
Serial Number Fitment Notice
Verify fitment by exact engine serial number and the correct cylinder head / rocker cover parts diagram before ordering. This spring is tied to the 224 cid 4-cylinder valve train, so serial-based confirmation is the safest way to match the correct internal engine part.
When This Part Needs Replacement
Replace this valve spring when the original is broken, weak, damaged, or when the cylinder head is apart for valve train service or rebuild work. Because current parts diagrams place it directly in the valve train with the valve stem seal, retainer, and keys, spring condition matters to proper valve control and head service reliability.
Installation Notes
Install this spring only after confirming the correct MerCruiser 470/470 MIE cylinder head parts breakdown. Current OEM-oriented diagrams place it with valve stem seal 75624, valve spring retainer 75412, and valve stem key 547971, with 8 springs required per repair.
Alternate/Superseded Part Numbers
Current Mercury dealer references show 75411T as the superseding replacement for 75411. Aftermarket cross-reference sources also connect 24-75411 to MerCruiser 3.7L / 224 cid 4-cylinder valve spring replacements.
Parts Desk Insight
For an internal engine part like this, the important match is the exact engine family and cylinder head diagram. Small valve train parts can look simple, but confirming the 470 / 224 cid 4-cylinder application first is the best way to avoid ordering the wrong spring.
