I just bought a 2006 Avalanche and noticed in your picture you installed either a Keel Guard or Keel Shield. Which one did you install, how long ago and have you had an problems? My dearler is concerned the paint won't hold if I install a keel shield or guard. He feels the paint will pull right of the boat.
Also, have you had any problems with Porpoising? I have a 150 Optimax with a 23 pitch Tempest and it seems to Porpoise slighly a mid range taking corners.
