Picked up my new 2021 X 18 with F150 Yamaha on the back Thursday and got on the water today for the first time. Having owned 2 Xpress boats before this one I was very impressed with the improvements they have made to a lot of small things that have caused issues with many others before. Caulking all around the top cap, rub rail and across the transom and underneath all the compartments that have caused leaking, drain plug hole was ground smooth, added 2 more cup holders for driver and passenger and they appear to be glued in. As for fit and finish that many have complained about, I could find nothing to fault after going all over the boat. Now for my question, after the 2 hour break in and finally getting to let her run for a bit I got 57.5 to 58.6 and 57-5800 rpms with the Power Tech prop OFX3R 23P and no porpoise at any speed but I did have a little chine walk that I'd like to get rid of. PTP is somewhere between 4 and 4 1/2 inches. Am I correct in thinking that raising the motor up will help relieve this problem. I could drive through it but had rather try to eliminate it. Actually satisfied with the speed and rpms are close to what they should be. Love the boat and sea dek is the best thing yet.
