HELP Removing Stuck Oars From Inflatable Dinghy

[Paul LeMenager]

Do you know how to remove stuck oars on an older Nisson inflatable dinghy (no longer made). Please look at the photos. I think this unit has oar locks that are different than modern oar locks. After removing the screw it does not come apart as I thought it would.
I have debated using WD40 or PB Blaster, but do not want to ruin the system because I still row to my mooring. I want to remove oars so I can store the dinghy in its bag.

Thanks
Any helpful info will be appreciated!

Images added. Those look like they would just pop out with a lot of pulling force.

Put the screw back in loosely and tap lightly on it while pulling up on the oar.

Thanks Les I'll try that - should I add some WD or PB if on really tight? Do not want to damage dinghy.
Thanks

When you try and work oar lock out, make sure you try rotating the oar. Like the oar handle point out, or the handle pointed toward the bow. There could be a channel lock in there to keep the oar from falling out. My Mercury dinghy has a channel lock so when I insert the oar it is facing in a direction that would be considered not "normal" in use.
