About the game

Build your dream boat, repair engines and deliver goods in the Marianas like the real deal.

Original Steam description

In this boat mechanic simulator: A tropical paradise, boat engines that need the special touch, and no honest way to pay for parts.

REBUILD IT

After years of neglect, your boat is ready to be reborn. Repair, upgrade and customize with your personal flair. Collect used boats or make money selling them!

WRENCH, FLIP, DELIVER

Learn to fix outboards, find and flip junk boats for cash, and deliver goods with whatever still floats. Pull plugs, fill tanks, diagnose real failures.

Live the island mechanic life, not a simplified version of it.

BUILT FOR MECHANICS

  • Mechanically accurate engines with individual parts.

  • Real working instruments, gauges and tools.

  • Diagnose failures yourself; no auto-fix, no shortcuts.

Grab some parts and check me at the marina.
