I have a 2014 Mercury 115 Optimax (2 stroke) running a 20 inch LaserII prop on a Flo-TorqIII prop hub.
I had to replace the hub so I ordered the same part number I had purchased 2 years ago.
When the hub arrived, it had the part number I ordered but looked very different. After research I learned that the Flo-Torq hub series has been replaced with the SSR series, so I was ok until I read a confusing note indicating the hub was not to be used on 2 stroke engines.
I found this chart on the Mercury website. Do you interpret this as not suitable for 2 strokes? If so what do I use.
