Good luck! Trying to put in an another bilge pump. Complete nightmare. Wiring tube is full. I have a snake all the way from console to rear corner, can’t get it through. I tried another snake from rear to front, stops after about two feet. My Ranger would have taken me a few hours but the tubes were huge, old stratos was the same. These are only 3in at best and packed right full. Next I’m going to try a “grabber” blindly to see if I can grab the snake from the front. Using fiberglass snakes, flexible ones were just coiling in compartments which tell me tubes might not be through boat, just at beginning/ending of sections. 😡
