Sterndrive displacement speed steering problems
 

Hi,

I have a sterndrive on a 20' trailer boat and it zigzags a lot at slow
speeds which I understand is a generic problem for sterndrive boats, and may
be to do with water flow around the back of the boat and the stern leg. I
have also heard of one manufacturer that uses some type of vortex generator
around that area to combat the problem.

Does anyone out there know of any aftermarket add-ons that may help, or of
any information sources on the issue.

Sterndrive displacement speed steering problems
 

Trim tabs all the way down (bow down) and drive up (not trailer up) helps on
some.
What actually helps a lot more is a lot of low speed experience and then you
will stop constantly over correcting.
