  • Remove the window by using a putty knife to pry it away from the frame.

Detailed Instructions For Removing The Old Portals

Removing the old portlights from the boat requires careful attention to detail to ensure that no damage is done to the boat or the portlights themselves. Below, we provide a detailed step-by-step guide on how to remove the old portlights effectively:

  • Protect the cabin interior by using tape to cover exposed areas.
