The friction lever's internal spring helps to counterbalance the weight of the hatch lid. The friction it provides adds some stability to the lid when the hatch is open. The friction is adjustable by way of the Allen head fastener on the axis of the pivot. The spring tension is not adjustable.
Over time the friction lever may loose it's ability to hold the lid due to a combination fatigue of the spring and wear to the friction surfaces.

As Catalina introduces new models, it is likely there will be other boats that use this same hatch. There may be other instances where this was used. It is also the case that not every boat described above used these. Please verify that your boat used a Lewmar Offshore series hatch matching the dimensions above.
