I finally got around to putting a manual jack plate on my 700LXDC.
Initially, I raised the motor approximately 5/8" from the original height. Had it out on the lake yesterday for a test. The RPM, acceleration and speed figures were pretty much the same as before; I'm still turning a couple hundred RPM under redline at full throttle and maximum controllable tilt, so I think some additional raising is next.
Several handling improvements were immediately apparent. Previously, at around 3000 RPM, the boat felt like it wanted to fall off plane. Now, it stays on plane smoothly at 3000 RPM. Also, there is much less bow rise on the hole shot...it comes out of the hole much "flatter." And, I used to have to get on the trim switch to tame porpoising in some situations; didn't have to do that at all.
So, the much ballyhooed handling benefits of the jack plate are there, now I have to tweak for a little more speed. I'll post updates. I also took pics of the installation and will post a project when I have final settings.
