Mariah G21 2011. Engine Mercruiser 4.3 MPi + Alpha 1. The propeller was apparently badly damaged by the previous owner. Can someone tell me which propeller was installed on the boat at the factory?

Prop installation would depend on where the boat was destined to be sold. IF i had to guess i would suggest a 3 blade 19" pitch was standard but a 4 blade 20" pitch would be good also.

thank you very much for your answer. I was thinking about 19 inches too. the previous owner sold me a boat with a damaged 16 inch propeller, says it was factory installed on the boat. I think it's not true
