Re: boat list bad

If the boat dives then you possibly have a hook in your hull.
If it just pulls that way then something as simple as adjusting your anode tab. And yes, trim tabs will certainly help.
As far as the water is concerned it might be an issue if it builds up on the port side only - I don't see that being the culprit though.
Very possibly that your motor could be the source of this. Try putting it back a pin or two and then run it. Will be trial and error but this way you can start to get it narrowed down.
You didn't mention if this is a new problem or ongoing.

Re: boat list bad

With your engine being in that position it is pushing the bow down. It needs to be trimmed up. Don't go WOT until you adjust the trim.

Find out where that water is coming from. Does your boat have a live well?

Re: boat list bad

Most often a boat will list to port at speed because the bow is too low in the water. The cause is often motor trim (too much negative trim) or a hydrofoil.
