Counter Rotating Prop code

Hi all,

Over the christmas break I managed to hit a submerged rock with my propeller which has caused a small dent in the blade.

The motor is a 1996 175 hp Mercury Offshore and is counter rotating (the boat has one engine, I anticipate the previous owner purchased a used counter rotating motor from someones twin rig).

I can't detect any change in the performace of the boat or vibration of the motor since i have damagd he prop.

 

The code written on the prop is: 48 16545 A40 21P. I have been able to find a used on online for about $100 but I want to make sure it is counter rotating prior to ordering - is there something in the code which reffers to counter rotating?

 

Given that i am unable to detect any change in the performace of the boat or vibration of the motor since i have damagd he prop is it nessecary to replace the prop/would it be a good idea to file down the dent to reduce its profile?

attached is a photo of the prop code.

 I clipped a chunk of reef with one of my props some years ago. I simply removed it and panel beat the small dent out of the leading edge with a ball pein hammer on an anvil. Took 5 mins and good as new.
