Chris - your boat is definately prone to chine walking at these speeds (and at slower speeds). You might find that lowering your engine height will help with onset of chine walk. There are also...
Styler - yes, possibly… often raising motor height can change the dynamic balance of the hull sufficiently to mitigate onset of chine walking. trimming down will almost always help. here's an...
Glad you've got it all worked out!

Mr. McGibletts - chine walk is pretty common on performance hulls like yours.
As the hull accelerates, lift increases and the wetted running surfaces that are required to support the hull are...
your experience is pretty typical for a performance vee hull, and it's occuring just as your hull enters the "hump zone"...quite predictable.
There are indeed, some things you can do to address...
would anyone have a Power Curve (HP vs RPM) for the 115hp loop charged V4 ETec 115hp Evinrude? AND fuel efficiency vs RPM?
many thanks, in advance!

gmchiryder - what are the differences between the 150HO and the normal 150? Is gearing the same? HP same? is the 150HO lower unit exactly same design or does it have a different nosecone and water...
what are your experiences with the 150 E-TEC HO engine? Is performance much better than the 150? Reliability? I am looking to get a new engine, and wonder if this is the one that i want.
