Low speed wandering is a normal issue with these style boats. Installing Smart Tabs can help. In the mean time just keep the wheel straight the wandering averages out and constantly correcting just makes it worse.

Some wander more than others.If you pay attention you can anticipate its motion and avoid over correction.
And as suggested smart tabs can help.but apply then as lightly as possible a little at a time.
sometimes when used too aggressively the can cause strange handling and poor performance.

Can be scary while driving through tight spots (channels, by docks) but practice in large no wake areas and you will gain confidence in the 'let go, use the force' technique - I'm still working on it myself. Just watch it next time out and you will be pleasantly supprised. A perfect 'S' curve - end result....straight!

My Tahoe 216WT does the same thing as did my prior boats, except the duckboat..ha. Smart tabs can help.
