Specifications

Output
65 Amp

This is the Sierra 18-5960, a 65 amp alternator with a 2-wire connection and serpentine drive. It is shown as a fit for Mercruiser engines. The OEM reference number is 807653T, which is the figure to compare with the unit you are taking off. The maker's own number is 18-5960.

Our take

The 65 amp rating of this 2-wire Sierra alternator sets how much charging current it can supply, so add up your loads against that number. It is shown as a Mercruiser fit, so check OEM number 807653T against your old unit.
