I Have a 21 Aeromarine cat. Running a 5 port NR, Think it has a NR pipe and am running exhaust thru the transum using larger tube and coupler hose(3/4" ID). What should my pipe length be and what prop. Also,the strut is under the boat and what height should it be. Can replace pipe with OPS3280 and run it up thru the cowl. Don't really want to cut it up but I will. Have tried a x440/3,x440/2, x640, x442/2. Need help from the pros for the proper setup. PLEASE HELP. Thanks Tom
