A perfectly straight bottom boat will not run above 30mph without bouncing. First step is to adjust the weight in the boat. if that doesn't stop the bounce next step depends on how much you want to spend. A lower rake prop will help, rake causes bow lift, a expensive attempt that may not work completely.
If you have never heard of a hook in the bottom of a boat, you need to look at the bottom of most hi-perf boats. We have been hooking boats for 30 years. The difference in a small hook and trim tabs is the length of the angle. Trim tabs are usually 6" long behind the boat. That small area requires a steep angle to accomplish the work. A gentle hook in the bottom starting that the back of the rear seat and ending at the transom gives you a much longer area to accomplish the same thing, no speed loss, no gathering vegetation in reverse. Like I said, been doing it for 30+ years, never slowed one down yet. Ask anyone that has purchased my hulls after I'm done with them. Ask anyone that has seen my rigs run. Better yet, here's the boat I currently own, guess what, it has a hook at the rear of the hull on the bottom. 4 stroke 40 merc with a 60 pcm in it.
I would start with a 1/8" hook and add 1/8th at a time until you can trim about 2 degrees positive with a normal load. The most I have ever hooked is 1/4". Hook only the two outside corrugations, DO NOT HOOK IT IN FRONT OF THE MOTOR!
Here's a video of the boat in the pic with the hook running black bayou:
same old 1552 WeldBilt and exact same old Merc.
