Pressed in or replaceable hub?

[Oprod]

I’m looking for a prop for a 2005 Yamaha hpdi 250
What are pros and cons between the two different styles of propeller/shaft attachment?

Rubber can fail and leave you stranded. Then need to take to a shop to press the old one out and press a new one in....

Square bore/flo torq normaly don't fail, But you can replace yourself at home or on the water if you have the tools and spare drive sleve. These hubs also allow for fitment of propeller on most any outboard with the correct hub kit.
