Hi, I was looking to buy a prop off iboats. The factory number from the prop is 48-78120A4019P. It seems like there are a lot of options for this prop. I was hoping the solas prop number 1511-145-19 would work. I think my prop is 14" this one is 141/2". Do you think half an inch would work. They also have another make thats more expensive. its the Michigan wheel part # 031025. Its a 14". Will the cheaper one work. Anythoughts on a 19 pitch prop for my boat. Thanks
