The lower unit on this 14 HP model has a splined hub rubber cushioned propeller and no drive pin.----Believe me , you can look this all up on line if you are not familiar with these motors !!---And I have seen more than 1 of these 14 HP models.
The manufacturers use to sell 50 cent shear pins.------But because folks are lazy today they sell $150 new props and expensive driveshafts.----A " win , win " for the companies.
