SHO Power – Unleashed
At JC Maritime Services, we’re proud to offer Nizpro’s performance tuning for Yamaha V6 SHO outboards. With this upgrade, your 200, 225, or 250 horsepower engine can climb to an impressive 332hp—delivering the kind of performance Yamaha built into these motors but never released.
Beyond sheer horsepower, many customers also see fuel economy gains of up to 15%, depending on boat setup and conditions.
⚠️ Important: For best results and long-term reliability, your engine must run on 89–90 USA / 95–98 AUS octane fueland follow Yamaha’s recommended service intervals. Ignoring these requirements may reduce performance and risk engine damage.
If your ECU ID is not in this list please locate the "Prog. ID" or "Ver. ID" on the ECU and re-check.
If it is still not in the list after that, please select "Contact Support".
