Hello, I have 1999 Hunter 310. GREAT BOAT. I need to replace the piston on the Selden Rodkicker. It only says the name and not nomenclature on the outside. Has anyone done this and do you have the part number for a not Arotron piston? I would appreciate an assist. Since I am asking, has anyone added a Windless? I am looking at the Lewmar v700. Thoughts, suggestions. GO Navy!
