    2021 redesigned supercharger clutch Waverunners

    Is the new redesigned s/c clutch ( 27 vs 24 teeth and larger diameter ) only on the 2021 GP1800R SVHO , or is it on the 2021 FX SVHO as well ?
    Thanks in advance, Brett.

    What is the correct Yamaha OEM part number for the 2021 upgraded SVHO supercharger clutch?

    The -10 designates the updated 2021 version, correct?

    Looking for someone who has actually received the new part to confirm the part number on the box.

    I wonder if is a direct replacement when you need to replace a late model clutch on a SVHO 1.8 engine

    Last time they changed the teeth it we where able to install it on the older engines, even the SHO's if you installed the matching idler gear. Hoping for the same result, if the new one proves more durable then maybe ill bump up the boost!

    For clarity, the more teeth is the sprag teeth/ the teeth that hold the clutch. not the gear teeth that spin the charger. The change last time was the teeth for gearing and why the idle gear had to be changed.

    Nobody has received the new part. They are not available yet. Once available, the GreenHulk store will have plenty in stock and I will make an announcement on the forum.
