I’m assuming I need to replace the bilge unit on my 2000 518vx because it’s old and kinda beat to hell. Is Rule the brand that Ranger uses? Or does it matter. I used an Attwood 750gph on our last boat and it was phenomenal. I do want to try and stay consistent with the bilge switches for manual and auto but I may just go with an auto all the time setup like my last one. What are you guys running or suggest I use since I’m a big novice when it comes to bilge pumps. Also, my hose is corrugated coming out of the bilge. Shouldn’t I switch to a smooth hose so the full power of the bilge can be utilized? Thoughts? Thanks.
