Contact skipper 9 on here best bags u can get most bang for your buck I run them off the side of my 272 with no issues as long as you take the time to make your ropes the correct length u wont have any issues with them getting into your prop I have a inboard and don't have any problems I like to make the back lines and the front ones a little long and then just wrap them around the cleat more to get them adjusted corectly and that way I can run different size bags also or I will adjust the back of the bags with the line to controlling how much drag I have to controll the boats speed down to the tenth on speed because as the capt Jim informed me if u can't run the correct speed you won't catch the fish seriously just contact him on here he will help u out
