I replaced the gas spring on the observers' seat on my 2016 Nautique 200 with a factory replacement Master-Lift ML36-80, an easy install, but it also failed to hold up the seat. I informed the fine folks at Nautiqueparts.com who sent me a replacement as perhaps I got a lemon. However, replacement unit also failed to hold up the seat. They are working on it again, and were to speak with the factory. There is nothing wrong with the seat, it is not waterlogged or otherwise damaged.
Has anyone had this problem? Should I go to something heavier than 80 pounds?
