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