I have just purchased a 1984 270 family fisherman sportcraft. It has a 350 260 hp inboard, 1.91:1 transmission. I was wondering if anyone can tell me if the 18 x 22 prop I found in the boat is the right one for it. The 22 pitch seems off to me but maybe with that ratio it will work. If you have any info or know where I can get it it would be appreciated thanks. Fish on!!
