I bent my orig prop last year and called acme. was sold on the 1847. installed it last year at the very end of season and liked it for the short test drive. june of this year I final had a chance to ride behind my boat with the new prop and my new murray 150. its awesome. smooth, great accell. same fuel milage. quiet. my oj had a weird noise while driving, the acme is sooo much better. I highly rec it to anyone.
