If your 50hp Tohatsu is the TLDI model, our '05 Nissan is the same motor with a different color scheme, and it is one of the lightest of the 50s [which would contribute to a high stern/low bow attitude when at rest]. Your engine speed at WOT should be in the range of 5,150 - 5,850. We have a 12.1" diameter x 9" pitch prop, and top out at 5,200.

From your description and the previous posts, you maybe fine especially since any loading or mods to the back part of the boat - like extra batteries and water tanks, gas tanks, and midriff bulge will "level" her out. I originally thought there was a lot of nose down attitude but if your similar to the others it sounds normal, although my M seems to sit level but then it has a lot of weight in the stern when I am at the helm.
Check your prop, yes there are quite a few discussions about rpm, WOT, and prop sizes that you can search for and read. If you seldom run WOT a prop that takes a bigger bite at the low end may work better for you (and be the reason the previous owner used it)
I seem to remember a thread where the late Catagale waxed eloquent on the subject of WOT and low end torque.

Hello,
I always considered the "bow down" attitude reduces drag at the stern, thus you go faster.

And here I thought it was the M bowing its head to the stern heavy X

X...bow high = fly (bye, bye)
M...bow down = plow (slow)

When I first bought my 26M in 2004 the dealer had installed my pressure-water reservoir under the V-Berth all the way forward. With that tank full, I felt I had way too much bow down - and the spray I got in the cockpit under power confirmed this. I relocated that tank (it is a soft-sided model) under the rear berth, and I like the trim of the boat a lot better. I guess the lesson is - be mindful of what is up in the bow.
Also, remember that when you are looking at that black waterline stripe, your own bodyweight (and probably your passengers) is not in the cockpit causing the stern to go down a bit

Do not try and judge the waterline with the Admiral in the cockpit alone, either, because of course she is so petite that she represents negative weight, and the boat will actually float higher with her on it
