Awaken the V8-
At JC Maritime Services, we’re proud to bring you Nizpro’s industry-leading performance upgrade for Yamaha V8 Offshore outboards. With this tune, your 300 or 350 horsepower engine roars to life with up to 425 horsepower—a true beast on the water.
Beyond raw power, this upgrade also delivers efficiency. Many boat owners report fuel economy improvements of up to 15%, depending on boat setup and conditions. Check out the tuner’s notes below for real-world results on a 43’ Everglades.
⚠️ Important: To ensure maximum performance and protect your investment, your engine must run on a minimum of 89–90 USA / 95–98 AUS octane fuel and follow Yamaha’s recommended service intervals. Skipping these can reduce performance and may cause 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"
