Hi, this might be a bit left field of what you were looking for but here goes.
Consider changing your prop(s). I trialled 5 Props for suitability Speed, torque, Trim etc.
I found a set that provided all my requirements including providing a trim range that would allow me to push my bow down in the worst of conditions the boat (err me) would handle.
I also put a heavy tow rop right in the forward area of the locker, and it just stays there. If ever needed (not yet) its there.
Best of luck on whatever measure you take.
