Solas YS-DF Dynafly Impeller

The stainless steel Dynafly impeller for the SHO/HO FZ, FX, VX and GP1800R models – this is designed around creating maximum pump efficiency- resulting in excellent bottom end efficiency and great rough water hook-up.

The YS-DF Dynafly impeller fits into the Yamaha HO 155mm pump with the large 25mm shaft used in the models listed below. Also, can be a great performance upgrade on some late model Yamaha Jet Boats!

It comes with an aluminum nose boot and an impeller tool. We do recommend buying the driveshaft holding tool (WR014H) for ease of installation.

We will custom pitch your impeller to meet your needs, are you riding at elevation or with a tune? Let us know and we’ll pitch it so you’re getting top performance!
