A turbo swing is designed for towing inflatables and skiing behind a boat with an outboard motor. This swing can tow up to three separate ropes. Originally designed for the 115 horse Evinrude E-Tec. The configuration for the mounting brackets are universal and will fit a wide variety of motors up to to 150 horse. It is only been used one season and is still in brand new condition. I also have an extra mounting port for it. Purchased brand new for $1000.00 this not a cheap accessory for your boat. but it does work extremely well for skiing text 415-261-161seven.
