DESCRIPTION

The Definitive Repair Guide for Mercury V6 2-Strokes

This Mercury Mariner 105-225 HP Service Manual is the factory-issued technical resource (Part No. 90-824052R3) used by certified marine mechanics. It covers the golden era of Mercury’s V6 power, from the workhorse XR6 and Magnum III to the high-performance Pro Max and Super Magnum series.

Unlike generic aftermarket manuals, this PDF provides the specific factory tolerances for the 2.0L, 2.4L, and 2.5L blocks. Whether you are diagnosing a “no-spark” condition on an ADI ignition, rebuilding a MercCarb, or timing the oil injection pump, this manual has the step-by-step logic you need.
