OEM MerCruiser 865444T 3.5-Inch Grooved Idler Pulley – Quicksilver
Description
Description
Quicksilver 865444T is a 3.5-inch grooved idler pulley for selected MerCruiser V8 serpentine-belt systems.
Product details
- Manufacturer part number: 865444T.
- Manufacturer applications include selected 350, 377 and 496 CID engines.
- Part-number-specific replacement for the corresponding idler position.
Fitment and selection
Confirm 865444T in the engine serial-number parts catalog before ordering; other pulleys in the same belt system may differ.
Identify the correct pulley
The MerCruiser 496 MAG and 496 MAG HO seawater-pump parts diagrams identify 865444T as the grooved idler. The non-grooved idler is a separate part in the same assembly. Match the part number, belt-contact profile and engine serial number before ordering.
