fitting the goose neck on a NE Dory

I am at the point of installing the sailing rigging and was curious about the fitting of the goose neck.  It appears that the rod that goes into the boom iis just a press fit. Can this be right or am I missing a step??

Thanks for your help, Gary

Outhaul tension keeps the boom on the gooseneck.  Not once in seven years have I had the boom come loose unintentionally.
