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

No the Mainship II came with various engines. Standard was the Perkins T6.354 at 160 BHP. They also made several early ones (1979) with a 200 BHP Mitsubishi. After that probably 1981 they used the Perkins T6.3544 at 200BHP.
They were a little lighter but 16 knots was a stretch even with the later Perk. 9 maybe 10 with the Perk 160, 12/13 with the 200 Perk, maybe 14 if it was lightly loaded.
I also had 42 x 12 trim tabs and I could be "on plane" at 8 knots without doing any tricks to get there provided the water depth was at least 10 ft. After my repower with the Cummins 270 I could run with an almost flat wake at 14 knots (tabs up).
