Compensate
On my 356, the bow veers sharply to stbd when I apply reverse -- unless I compensate. I went out and practiced coming up to a mooring until I figured out what to do. If I'm at a standstill and apply reverse, I start with the wheel 1/3 turn to stbd. If I'm moving forward and want to back down, I turn the wheel 1/4 turn to port (and then to stbd once the weigh is off.) I can back as straight as I care to now, and I also know that I can use the thrust to cozy up to a pier on the stbd side if I care to. I can also use the veer to counteract a crosswind. So, don't fight it, learn to control it and work with it. Makes you feel pretty competent, too.
