I have a two-stroke Johnson, two different props. I did not raise the X dimension on this Whaler. On the previous 13s and 15s I had usually had a 2" piece of wood under the (on the transom) outboard to raise the X-dimension.
I do not experience any chine walking at 41 mph, I trim the boat way-out, watch my tach, watch my speedometer, and drive it like a Hydrostream. Get your Whaler dialed-in.
Boating in the Whaler is fun.
