I have a 2009 Outback** direct drive. What is the factory propeller size? Including the bore size.

I am considering getting a 3-blade Acme 543 (13 x 11.5) or the 1229 (13 x 11). I am probably 50/50 on wakeboarding and wakesurfing. My OEM prop seems to struggle wakesurfing with 1,200-lbs ballasts, trying to maintain consistent speed.
