I thought all the MKII's came with Perky 200HP. They could wallow up onto plane to 15-16 knots + because they were the lightest of the series.
The hull runs happy at 8-9 knots at a pretty lazy throttle setting, that brings the forefoot up just a little and settles down the wander. The boats with 200HP will plane (clean bottom, not too heavy) at 13.5 knots but won't stay on plane in a turn or chop. 14.5+ I found mine would stay up comfortably.
There is a technique that involves perfect conditions, perfect timing and a lot of luck for planning a lower HP Mainship, or so I've heard. You run hard an produce a large wake, then throttle back and let the wake catch up and then hit the throttles and "surf" up onto plane. Urban legend maybe, I had 200HP and 42" trim tabs so I just pushed the handle with the red ball
