Product matching notes

Use these checks together with the application table before final ordering.

How do I confirm CF-12174N-6G fits?

Compare Part No, OE numbers, Lester Numbers, the application records, and the spec table. The page is organized around Mercruiser Model 120, Mercruiser Model 140, Mercruiser Model 175 and related applications.

Which fields matter most?

Start with Voltage: 12V, Amperage: 55A, Rotation: BI, Pulley Class: S6, then cross-check OE numbers Mando AC155616, Mercury Marine 807652, 807652T, Prestolite 20130179.

What if I only have a photo or partial number?

Share label photos, drive-end and connector shots, and any partial number or Lester Numbers 12174. That usually narrows the match quickly.
