I run one now. It is a pain in the ass to install and remove. But it is fast as f** on the flat water. I too am using it for surf; it does not provide the instant bottom end I need to fight the currents and to get me out of the hole. I am responding to this old thread because it is relevant to me now, and I need a different mounting bracket because I now have the OEM 61x head, after having seized my last motor on which I had the 62t head. Bracket pics would be greatly appreciated.
