First, safety is a factor. Trying to save a buck is foolish. Have the boat lifted.
The installation of a new 7/16 inch line for your centerboard is the same for all hunter water ballast boats. Information in the owners manual coupled with installation by Rgranger directions is the way you should consider. I was involved with the design of your boat. In fact I am the bald headed with gray hair felllow in the pictures. If
@rgranger and
@Kermit are willing to come and help you, take them at their offer. I taught them.
They have my contact should any questions come up
