This is a Foil Drive Assist electronic foil motor Key points: -In great condition, comes with everything you need to get in the water -The Mast adaptor is for the Axis 19mm mast. (other mast adaptors can be bought from Foil Drive for $165) -This has a brand new "durable" (grey) hub and propellor set. -The only thing that doesn't work is the SUP paddle mount adaptor. These can be bought new from Foil Drive for 99 bucks if you want to do SUP. (i have just used the broken one and taped it to my paddle for the same result.) -Battery is still in great shape and has been properly de-charged for any time in extended storage. I get about an hour of use (I fall a lot, hence using the motor to get up quite a bit). -Has enough juice and power to be an e-foil for me(I'm 80kg, but note this is recommended as Assist to get up on the foil, not an e-foil.)
