I have a 2022 Ranger Z520R. I have owned 3 rangers before this one. I never had a Ranger to chine walk until now. It starts to walk at 65 mph. I had a Ranger rep come ride with me. I was embarrassed. We could not make it walk. I told him, the only thing i did different was I hadn't filled it with fuel. I ran it several trips without fueling up because I was having trouble with the fuel gauge no being correct. I was just going to see how low I could run before it would move on the gauge. The rep said more fuel on board would only make it better as far as chine walk. The next trip out I filled up with fuel. I added 22.5 gallons. It is back. The walk is uncontrollable. I and a couple of friends all with plenty of experience cant drive through it. It only gets worse with any combination of jack plate or trim until you trim it down enough to get under 65 mph. I talked to the rep about it he is going to come ride again. I noticed in another thread where BUB Tosh on instagram running his Z520R at 74.1 MPH with no chine walk. If you will notice he only had 15 gallons of fuel on board according to the gauge. Any Ideas how to fix the chine walk or at least make it tolerable? I have ran a 23p 3 blade fury and a 24p 4 blade bravo, not much difference as far as chine walk. I will try to post after the rep rides again. Love the boat other than the chine walk and a few other little glitches.
