Quicksilver 51100008P Alpha One Gen II Star Drive – Standard Rotation (RH), 1.47:1 Gear Ratio for 350 MPI Alpha

The Quicksilver 51100008P Alpha One Gen II Sterndrive is a complete, ready-to-install replacement drive for the Quicksilver/Mercury 350 MPI Alpha drive system. It was specially developed for high reliability, long service life, and optimal performance – ideal for sporty pleasure boats, runabouts, and numerous MerCruiser installations with 350 MPI engines.

With its standard rotation (Right‑Hand / RH) and the 1.47:1 gear ratio, this drive is perfectly matched to V8 power and ensures excellent acceleration, efficient power transmission, and smooth operation. The spiral-cut steel bevel gears have been optimized for minimal noise levels and offer impressive robustness even under demanding use.

The combination of the Tri‑Paint corrosion protection system and the proven XK360 low‑copper aluminium alloy effectively protects against electrolytic corrosion and makes the drive extremely resistant – even in harsh marine environments.
