Hello there,
Just happened to find your message. Nowadays the TurboSwing can be trimmed such that the pull is substantially higher. For a closer look, please go to our website
www.turboswing.com and view the video 40-175 HP, and see all kinds of acivities, including wake-kiting, towing a 5 person banana, 4 skiers at the time etc. Things you normally cannot do with a ski pole / pylon. For the 150 Yamaha we recommend the XXL, which is shown on the video on the 175 Suzuki and 100 Yamaha, now selling at GBP 423,- delivered. Installs within an hour.
Contact details can be found on the website, or drop your phone nr. and we'll be happy to call you back.
Best regards,
Peter / TurboSwing
