I need to buy a new prop for my 322 Oday. There is a 14X14 on there now but Im not sure that is the right one for this boat. I have seen several different recomendations for size and am not sure which one is correct. I have a 1" shaft RH turn and a 2GM20F Yanmar engine with a Kanasaki transmission with a 2.62:1 ratio. The displacement is 10,250 lbs. Not sure what it really is but the guy at Black Dog prop shop wanted to know the operating weight. Im not sure I know that or can find out with out taking the boat out when she is ready to sail and have it weighed. I also dont know if the displacment is the weight before fuel, water, gear and people. Or is 10,250 the recomended weight loaded and ready to go. Thanks for your help in advance.
