There is two sizes of 5/16" tubing 5/16" x .014 x 36" is K&S # 1151 ..... This is the tubing you want ... and .....there is 5/16" x .029 x 36" (K&S 9211) - this you DO NOT want as it's (.024 thick wall) too tight ...........1/4" Cable uses 5/16" tube - if you use anything else it will destroy it self rather quickly - you do not want slop in the tube -- you want it snug fit ............Your issue (unless you used wrong thickness tube) is the real sharp bend --- the bend should be a gradual bend ------- yours looks like it will kink the cable -- will also wear out very quick at that point.........................
Do not run anything but 5/16" or you will be replacing it soon - fix the bend (kink) ....................When you bend your tube - put a cable inside it and make a gradual bend not a 'kink ............. 5/16" (.014) tube is for 1/4" Cables ............................. you should run small piece of 11/32" through the hull (gets glassed in) then the 5/16" runs thru it --- then if you have to change tube the 11/32" stays in boat and the new 5/16" will just slide through it. If you just glass the 5/16" tube then if you have to replace you have to cut out.. If 11/32" is glassed in hull --- then just take out old replace with new.
