2007 320 DA that lists

[Pat Bollom]

Hi. I bought a 2007 320 Sun Dancer this spring and when I'm going 20-25 it will list to one side. Seriously list like I think it's going to tip over?!?! It seems to do it more in the wind. The marina guy says I just have to get used to it - but it seems weird/dangerous. Do I need to do something with the trim-tabs?
Also - I sometimes (when going fast) get this trim-tab warning.

Any thoughts to share would be really appreciated.

Sound like you have a trim tab all the way down. I suggest reading your owners manual if you have not done that yet. ​

RIM TABS

​

The trim tabs are two flat
plates, hinged below the water
line on the transom at the rear
and are raised and lowered
hydraulically by using the
rocker switches located at the
helm. (Figure 2.9.1).
The trim tabs are used to adjust the sideways listing
of the boat due to uneven loading, a strong cross
wind or propeller torque. The twisting effect of
propeller torque is especially pronounced when
running the engine at high horsepower output. To
correct the listing, adjust the trim tabs to level the
boat. When the boat is level, right to left, the steering
effort will be the same for right and left turns.
Lower the trim tabs on the listing (lower) side by
pushing the top half of the trim tab switch in onehalf
second bursts until the boat is righted.
Using both switches to lower both tabs on a sideto-
side balanced boat will lower the bow, when on
plane, if the rear of the boat is highly loaded. Again,
use only short bursts of the trim tab switches to
adjust the trim.
When running at cruising speed, the trim tabs
should be fully up, unless the rear is heavily loaded.​

Pat,
I am assuming that you have V Drives and not I/Os. If not, you also need to check your engine, not tab, trim settings. You should have 2 sets of trim tab buttons. Before you go out, press and hold the set with the arrows pointing up for 6 or 7 seconds to ensure both tabs are fully up. Get up on plane and see if you are still listing. If so, as Vince, pointed out, you may have a malfunctioning trim tab that is stuck in the down position.

I would start by reading your manual very carefully and get to know your boat a little better. It sounds like you have a trim tab or an outdrive trim issue (providing you have outdrives). Both are easily diagnosed by being familar with your boat and manual.

By all indications that you are stating above, check your trim tabs. Bring them all the way up prior to getting underway next time. Adjust them accordingly when you come up to speed. This will most likely solve your issue, or tell you what is wrong.
