Boat rides uneven

16 posts in this topic

In my new Monarch when I get on plane with the motor trimed down the boat rides through the water tilted to one side.When i trim out the motor it helps but still does not ride level.What is causing this?The motor seems to be set straight on the transom.The cavitation plate is above the bottom of the keel at center and the edge of the cavitation plate is below the water line when on plane.Do I need to adjust the motor up one notch?Or will adjusting that little fin on the cavitation plate fix the problem?Or what?

Hmmm...does it lean to the side you're sitting on? (I just couldn't resist!)
Try putting your tackle box on the opposite side of ya! Maybe the anchor, too!

My experience with the leaning boat is a weight balance problem. The smaller the boat the more weight balancing is needed, even at running speed. A side mounted full livewell can be the cause. With all those fish your hammerin, that's probably your problem. grin.gif If your not catchin fish than Eyecatcher has some good ideas.

I don't believe it is a weight balance problem.Although the livewell is on the side that it leans to. smile.gif

You might try looking threw the arcives at walleye central there was some talk about this problem, not relating to weight distribution.

Fishhead, I have the same problem with my SmokerCraft 90hp Envinrude when on plane. Thought of everything and nothing helped. Then I noticed our neighbor in his Lund Grand Baron with a 200hp Yamaha doing the same thing on plane. he can't figure it out either. hopefully someone knows.

Does your steering have a lot of torque at WOT? If it does, the trim tab may be set incorrectly. The propeller creates both forward thrust, and lateral torque through a "paddle wheel" type of twisting action. This lateral force can cause the boat not to ride flat and can make steering difficult. The trim tab can be twisted slightly to counteract this force. Standing in the back of the boat it should be twisted slightly to the right, about 5 to 10 degrees. If you get the angle wrong you will know it by the torque on the steering. Just experiment a little and see if this helps.

Good luck!

I may have the answer. My dads first Tyee did this and it pulled real bad to the Right. What I found was that both batteries were mounted on the Right side of the boat. Both batteris combined with the driver all on the right was to much weight on the right. I rearranged things so the batteries were mounted just off center to the left(this balanced the weight)and adjusted the trim tab and the problem was fixed. The boat balanced and did not pull after that. I would check both, because you may have a weight balance problem and a trim tab problem if it is pulling real bad.ScottS

I just read a couple of posts about Crestliners having similar problems. The problem was the drilled holes for the motor mounting, one hole was drill 1/4" lower than the other one, so the motor was actually sitting on the boat slightly off of level.

Might check that out too,..unfortunately I think the only fix is a new boat because there isn't room to redrill a new hole.

Thanks for the replies guys.I think I will try playing with the trim tab first.I am amost certain it is not a weight distribution problem.The boat has a belly tank,and batteries are centered also.Locating people in different locations does not improve things much either.I have had quite a few boats and have never seen this problem this pronounced before.

You would notice the weigh balance problem even before the motor was running if you had one. Just put it in the water and it would be leaning one way. I am sure it is a trim tab problem.ScottS

I had the same problem with my 2000 Smokercraft Millentia with a 90 HP Merc. The gas tank and battery is on the passenger side (PORT) and the live well is on the driver side(STARBOARD). When the gas is full and a passenger is onboard it will list to that side. I fill my rear livewell which helps balance the boat and trim out. Maybe the Manufactures might want to take a little more time balancing there boats before putting them into production.

Just curious, what brand and size motor do you have?

MN-Brad, I have a 2000 Smokercraft Pro-Mag with a 90 mercury and when I am going at a good pace, the steering tends to pull to the left. Is this the problem you had?

    • Switched up my pick at the last second in bucket A and put Wheeler in there. Great ledge fisherman and sounds like this dude puts in more time on the water then any other angler out there.   A. Wheeler B. Evers C. Tharp D. Herren E. Omori   Sounds like the bite has been super tough. Will be interesting to see how it goes. 
    • They are drumming like crazy now. In fact, I even hear them at night. My wife said when she was a teenager growing up in rural Wisconsin, she always thought that drumming sound was the nearby powerstation.    
    • Lilac blooms are here, just haven't opened. Hearing some reports of good finds in the Houston and Lewiston areas of MN. I checked some new public areas today on the MN side. Could be decent later but too cold and wet right now. Will check some early season spots tomorrow but won't hope for much with the cold weather.
    • Nice!  Must have seemed forever waiting.
    • 6 months later and he is home
    • Three favorites at the moment.  By the time they upload, I may change my mind.
    • A few from Maplewood State Park on April 16th.  Non-professional, but they stood still long enough for me to get 'em.
    • You might be able to figure things out this week.  How big is your sump basket?  Is the  pump kicking in now?  Sit there for 15 minutes and count the number of times it cycles.  That should give you a decent idea on how much water is coming in.  Then figure out about how high the water has to go before it flows by gravity.  The spec for the pump will say something like that it can pump 2,000 gph at 10 feet of lift.  (the gph drops dramatically the higher it has to pump the water).  The answer to your specifics will give you an idea of how big of a pump you need.  If you match the size of the pump as close as possible to the amount of water your will face you can maximize the amount of time the battery backup will last.   Faced with this problem I took a standard boat sump pump and modified it so I could hook up a garden hose.  The I took an old shop extension cord and wired the pump so I could hook it up to a car in the garage.  So just prior to having Noah float by I could hook things up in the garage and be good to go for as long as I had gas in the car to pump up the battery.   Now that I am adult I bought a generator and wired the house to take care of things.
    • Inevitably at least twice each season I will leave the house, drive 45 minutes and walk some of my favorite grouse spots for hours and hours, seeing nothing.  Admitting defeat on that day, I will drive 45 minutes back home, only to find a covey of birds in the driveway...
