I've had my 265 for four years now and, quite honestly, feel lucky to have not experienced a lot of these bad-behavioral attributes of the hull. Perhaps it helped coming from a slew of other deep-v boats prior to this, including two other Grady's and a Carolina Classic. I'm running twin 250 four strokes (Yamaha) so the only difference b/t my boat and the OP's boat is the year; mine being an '05 and his or her's being an '00 so our deadrises may be a few degrees different.
My procedure(s) for getting on plane and cruising have been, for the most part, unmodified from boat to boat and are as follows.
1) Trim engines all the way in.
2) Slowly advance the throttle until the boat gets on plane.
3) Once on plane, begin to raise the motors until the boat "releases" from the water. Hard to describe from a keyboard but easy to feel when operating the boat.
4) Slightly trim engines back down and adjust throttles to desired RPM.
5) Give a look back at the motors to verify they are level and true.
At no point, unless absolutely necessary, do I ever touch the tabs. Necessary reasons include, but are not limited to, sea state and load balancing. I advise my crew that, while on plane, they are to remain where they are if at all possible. If and when I do use the tabs, it's just a click here or there because the boat is VERY reactive to small trim tab inputs. Click starboard/port down on the trim tabs and wait a second or three for the boat to react as it's not immediate. Once I get to my destination I trim the engines back down and retract the tabs so-as to 'reset' the boat for the next time I need to get on step.
We make longgg runs to the canyons here in the mid-atlantic and my approximately 500 hours of run time on this hull have made me a believer in it's superb ride and capabilities.
Bow-walking at slow speeds is just the nature of the beast, in my opinion. All of my deep-v boats have done it to a certain extent.
