I'm trying to find the correct gas supports for my engine hatch on a 2007 23 Outlaw. The boat had a 20# Attwood and a 60# generic support on it when I bought it a few years ago. They finally gave out and replaced with a set of 50# generic struts. Those would not keep the hatch open so I replaced with 80# and still no luck. I would like to replace these with the correct units, does any one have the part numbers or the Newton force numbers for the struts they are using?
