We can't confirm that the iScan Mercury will diagnose a 2026 Mercury 15hp outboard, so we'd recommend verifying before purchasing. According to OBDSTAR's official documentation, the tool's engine coverage centers on the Mercury G3 platform — DFI 2, Optimax, Seapro, Verado, and the 40HP–300HP range. A 15hp outboard falls below that stated range, and smaller portable outboards also vary in whether they provide a diagnostic connector the tool can communicate with, so support is not guaranteed.
The 2026 model year is also very new. OBDSTAR expands iScan Mercury coverage through software updates released roughly monthly, so the newest engines and model years are not always included right away.
The most reliable way to confirm is to check OBDSTAR's official supported-models list for the iScan Mercury, found under the "Function Manual" section on the OBDSTAR product page (https://www.obdstar.com/Products_356....), which is updated at the end of each month. For a definitive answer on your specific engine, you can also contact OBDSTAR directly with your exact engine model and serial number. Because the included M060 cable connects to the standard Mercury diagnostic plug, you'll also want to confirm your 15hp uses that connector rather than one requiring a separate adapter.
