The motor does not look too high. Is there a pin or something limiting the down trim?

It's hard to tell from the camera angles of the pics provided but the cavitation plate (plate of the lower unit above the prop running horizontal) should be at the same vertical position as the lowest level of the transom when fully trimmed down. Because the pics show the motor trimmed up, its hard to tell. If this is a short shaft and you can't get the proper alignment of the cavitation plate, than a transom "jack plate" may be the solution to give you the ability to adjust.

Back to the deep freeze here in the Midwest.

Forgot to ask if you have a tracking fin on the bottom of the hull (see attached pic). These relatively flat hulls tend to roll up on a turn and break the prop loos if there is no tracking fin.

 

Tracking fin is in place and solid. Thanks

 

I got a wealth of knowledge from the original builder of these boats. He might sell me some shims to tuck the motor under further. He said these hulls were designed to tuck the motor under further than most boats. Thanks

 

I run a wedge. They are available from several sources. It does help the 18. The original builder of the Hydrodyne 20 is Ab Crosby Jr.
