    Gallery: The Great Sea-Doo 18.5-Gallon Fuel Tank Upgrade



    It was a rainy Saturday on the Jersey Shore when two friends,Tommy Branella and Jason Frank, decided to perform a fuel tank swap on a 2018 Sea-Doo RXT-X 300. Since the ST3 platform was first released, a lot of gripes about fuel consumption sprung up. Yet, when Sea-Doo released the 2019 Fish Pro this year with a 18.5 gallon fuel tank and many asked, “Can that tank be retrofitted into all ST3 models (both 2018 and 2019)?” The answer is yes! But with some slight modification, of course.

    Can a 2017 RXPX 300 except the 18.5 gallon upgrade as well?

    I beg to differ. It will except the tank. However, it will not accept it.
