Enormous slack in steering on 26M. Is it normal to have to move the helm 90 degrees, back and forth to steer while underway?
The motor is synced and linked tightly to the helm, and mimics immediate helm movements. This issue is that the boat does not respond without exaggerated engine/prop swings. This is problematic when navigating tightly into slips and through marinas. Add a little wind and its a real nail-biting nightmare. But even without the tight navigation, on relative calm waters I just want to know if it is normal to move the helm, motor and prop so far back and forth to maintain course.
I'm self-taught, but I have repeatedly read and reread the process for motoring into slips and it's just not getting better. I've tried with the rudders and keel up and with them down, heavy and light load and myriad combinations. With and without wind. I usually have a mate on the bow with a long pole as a precaution. I have nearly hit other boats on numerous occasions.
By now you are probably laughing at me or at least rolling your eyes. So after you pick yourself up off the floor, just know I am a pretty handy and adventurous type; I have great spatial acuity, can tear apart and repair engines, telescopes, computers and trailer bearings and run a pretty mean 10K for a 59 year old. I fly drones and don't get in car accidents, but this lovely 26M is making me crazy.
So, is it me, is it the load in the boat, what...

Good looking boat!
You need to determine if you are talking about slack, or lack of responsiveness. Trying to maneuver a high windage vessel using rear thrust only, Is a challenge. It is very likely that you are having to turn the wheel significantly to get enough side thrust to overwhelm the windage effect. It will be even worse if you don't have any dagger board down. Mind your depth though - don't want to break a dagger.
Nope - we're laughing with you!

It will steer better at low speed with some dagger board down and rudders down. If I have to maneuver in tight quarters, I put some dagger board down, leave the rudders up, and drive in reverse. This is the most control I've been able to achieve at low speed. The motor thrust moves the stern, and the dagger causes the rest of the boat to generally follow it.
Check your rudder linkage (back of the aft berth) to verify all of the linkage is tight. Several of the bolts in mine were loose and allowed excess slop in rudder linkage.
There is a speed that mine waddles like a duck. Faster, or slower than that speed is ok. Find that speed and avoid it.
Windage: Remember all that interior room you fell in love with? Windage is the price you pay. We can all tell you a strong cross-wind docking, or trailer approach story that would curl your hair. And, you can't reverse onto the trailer.

My solution is to approach a spot that I can gracefully land - given the wind direction. Then, walk the boat where it needs to go using the dock lines. Calm conditions are not usually a problem.
I almost took out a line of slipped power boats, and nearly destroyed both rudders on my first heavy cross wind trailer load.
You'll get the hang of it.
