Overview

The 300XS is Mercury Racing's legendary 3.2L stroker — custom-built 2-stroke power that dominated the performance scene. This low-hour example shows just 193 original hours with 130–135 PSI compression across all six cylinders.

Rigged with the 1.62 SportMaster lower unit, single ram, and offshore trim. Compression and hours were just checked; the boat hasn't been used since aside from an easy 20-minute test drive that same day. Cowling and graphics are in amazing shape — the entire package is very clean. Photographed as offered, including the powerhead.
