Description

2026 Mercury Marine® 383 Mag Stroke

Best Value on the Water

Mercury remanufactured engines are factory refurbished with new components featuring the latest specifications and the newest technology, allowing you and your boat to benefit from improved power and reliability for less than the cost of a new engine.

Backed with Confidence

All Mercury remanufactured engines are backed by a one-year limited factory warranty. Mercury Product Protection is also available to provide up to an additional two years of coverage.

A Greener Solution

Engines from Mercury Remanufacturing reduce environmental impact by recycling and reusing major components brought back to OEM specifications. This reduces wasteful scrapping and lowers the energy and resources required to manufacture new parts.

Features may include:

Bravo® Sterndrive
  • The size and power of the 383 Mag Stroker 350hp engine make it an ideal replacement for 350ci and 7.4L engines in cruisers and large runabouts
