Product Specifications and Features

The Tohatsu Alternator Assy (P/N 399-06023-1) is a genuine OEM charging alternator/coil assembly used on selected Mercury/Mariner small outboards. It cross-references Mercury/Mariner OEM ref 16074 (commonly listed as 16074T in later catalogs). Use this part when replacing a failed or damaged alternator/charging coil to restore proper charging output when the correct match is confirmed.

Before ordering: verify your exact engine model/serial range and match the part numbers to your existing alternator/parts diagram to avoid ordering the wrong component.
