Do you have a picture of the mounting bracket? I was looking to buy an extra one so that I can move my motor from my main boat to my pontoon boat. Since the bracket goes for $40 + shipping, buying a used complete set-up may be an option for me.
The bracket that I have looks like the below picture. Is this the same as yours?
If it has the same bracket, I'm interested. It's a bit hard to see in the picture, but the motor mounts to the top plate. The top plate is held to the bottom plate by a single screw that you can remove by hand. This makes it very easy to remove the motor at the end of the day. As I leave my pontoon outside 365 days/yr, quick release of the engine is necessary for me to bring the motor into my house to prevent it from being stolen.
