    2023 Trophy T20 leaning to port while on plane

    just curious if anyone else has had this issue.
    battery is on port side under stern seat
    I have a spare anchor in port side bow storage
    just me and wife on boat she sits in seat in front of console
    boat has merc 150 4 stroke
    could this be from prop torque possibly
    was told trim tabs would help this problem
    any brainstorms out there?

    Welcome to BOC and congrats on your new boat!

    Does the boat list while at rest?

    Have you tried moving the anchor to the other side?

      I have noticed a slight list at rest that I would assume being from the battery being on the port side from manufacturer.
      I wouldn't think that an anchor would cause this being that its not that much wait.
      I currently am waiting on water test from dealer to see what they think I'm sure the trim tabs will correct this I was just not wanting to always have to apply themas I'm sure they will cause more fuel consumption.

        It may not take much weight to "unbalance" the boat.

        Yes, several small vessels will start off a little off balance depending on the boats features and battery/tank placement.

        They try to "get it right" but sometimes a compromise decision is made and things are not perfect.

        Move that anchor and some other gear you have over to the stbd side and see how it looks at rest....and how it performs at cruising speed.

        Let me be clear....although I am talking human beings here...........when I have guests on the boat (20 footer) I will tell them where I need them to sit......I explain my need to have the boat balanced from port to starboard......and I instruct some to go to the bow for water skier pull up sessions......after the boat is on plane, I tell them they can sit in the aft seats if they like....but those seats are not to be occupied while pulling up a skier.....it makes it hard on the skier and the engine............and there is no reason to do that to either one!

          Even my heavier 25 footer will list on plane as occupants move around. Water condition and currents will also have an impact. I adjust the tabs often during a cruise.

            trim tabs would without doubt fix any list issue but I would not want to have them deployment permanently to correct a dry boat issue. I have them on my boat to improve the ride in certain conditions and to level out of passengers and load created by an imbalance although I try to place external boat load evenly.

            I would rather consider adding a house battery under the other seat and have the benefit from that instead just adding tabs to counter off balance, Agree with the other comments that it doesn't take much to list.

            side note on tabs - I installed lenco tabs and although you have a number of settings it is not as fine increments as I expected so you might find if your list is minor the tab might over correct you to the other side.

              I agree with adding the house battery on starboard side will probably correct the list while at rest as it is probably only like an inch or so do that when I finally save the funds for the minnkota. buts what's strange about it is I can trim up and most of the lean will go away but its like the boat is trying to turn left and if I move the steering to the right it kind of straightens up unless there's a steady crosswind than its like the t top is like a sail and boat really leans then. as far as trim tabs I went ahead and got the Bennet bolt electric with the auto trim pro. kind of like the idea of the trim tabs learning your driving style and then automatically deploying as needed. these electronics are getting pretty sophisticated these days. couldn't believe it when I saw that all my gauges were digital on screen. not sure if that's a good thing or not as long as they are working.

                This behavior may be normal for that configuration.

                My I/O on the last boat would pull to one side when the boat was trimmed up and "skimming" across the water.

                I had a little sacrificial anode fin on the lower unit had to be offset a bit so that the boat tracked fairly straight and I did not have to "fight" it.

                Here is the picture--

                  Without nobody on it my 21 ft boat lists heavily to SB. It is the side with 2 batteries, all the wiring, helm. Maybe if I fill the water tank that it will stop leaning. At higher speeds it straightens out and I can trim it, but at low speeds it is a fiasco. Last week I had to go a mile at less than 7 kts, the boat did not want to go straight. Then when someone moved even a little everything was upset even more. I drove both trim tabs down which helped... a little.

                    any chance you have water logged somewhere ?

                      Not likely heโ€™s waterlogged. I pulled my water heater for a pressure test the other day, without it on board the boat is now listing starboard a fair amount. 6 gallons of water (50 lbs) plus the weight of the tank itself at something around 10 -12 lbs give or take. 60-62 lbs missing from the port side sure does present itself.

                        rcguy, I wouldn't hesitate to add trim tabs. You will like the results.
