If all else fails you could try fitting some of those "wings" to the Cav Plate. They have made a huge difference to my friends Humber which chinewalked like mad at anything over 33 knots.

I used to have a 5.8 with a 135 that chine walked terribly , at its worst on a flat calm, as that was when most of the hull would be out of contact with the water. I had a wedge fitted to the transom to tilt the engine back further as the transom angle was quite straight vertically, to give me more down trim, and I put some water ballast up front to hold the bow down a bit, and it cured the problem ...... thankfully, since it was a real frightener to be zipping along one minute, then slapping left and right the next.

I think contacting Humber would be a great place to start - is within their recommended power range and weight?
