when I come off plane my boat kind of goes to the left a little. it has never done it be for. what could I do to fix this?

steer right a little  ;D

Lol.  That was a sa comment, but a funny one.  You have probably thought of this, but is you baout loaded properly?  A steering damper helps to remove the effects of prop torque, but I am unfamiliar with this.

I remember hearing of that. A guy bought a boat that had been in salt water and the trim tab was pitted enough to cause a right hand veering at a particular speed. If your trim tab is also the sacrificial anode and is worn down those problems will develop. They also come loose and even drop off, but in that case you would have found the problem, unable to even get on plane without a struggle.

you know i have not tought of that,I have two deep cycle batterys on the left and then a fishing parnter so that could be it.

The torque of the prop causes this, but you may have a trim tab out of proper setting.

i thought the prop torque  will pull you to the right

 Yeah, you're right.  I must be dyxlecsic (sp?)?  I would still check out the trim tab though.

I dont have trim taps.

but I ask one of my buddys about it and he said that his pulls to the right and he ask me to ask yall how he could fix that.

Trim down and come off plane slower. If you come off top skid too fast it can cause the boat to pitch left or right. By trimming down, you get more of both the boat and motor in the water as you slow down.

As far as right hand torque, it can be due to improper setup. The cheap fix is a $15.00 torque tab. The more expensive fix is the torque tab with a jackplate. The most expensive choice is hydraulic steering. Before trying either varify that propshaft to pad distance is correct. Trimming too high or not high enough can cause the right hand torque issue as well. Trimming too high can cause prop slip percentage to increase, as will the motor setup being too high. If the motor is too high you will see a rooster tail shooting high above the cowl. Rooster tail should be almost even with the top of the egine cowl when on top pad. Just because the engines rpms running higher with the trim all the way up, doesn't mean the motor is trimmed to the sweet spot. Trimming too high in effect pushes the transom deeper into the water causing loss of forward bite because the prop is pushing slightly downward and forward instead of fully forward. Trimming too low or the motor setup being too low will cause the prop to have too much bite. This will cause the boat to not have enough lift and the boat will plow causing the motor and prop to have to push harder to reach higher speeds. Thus never reaching the sweet spot either.  A damadged prop, or improper prop pitch (prop is too big causing lower rpms resulting in trimming too high to gain max rpms.) ) can cause right hand torque as well.

Figured I would comment here if it's ok.

I've always found the torque tabs on the motor do very little at low speeds.  Too much hull drag for that little tab to compensate for.  They are primarly to zero the torque out at full plane when the boats at/near max speed and properly trimed out.

Boats leaning and pulling hard left or right has more to do with weight balance and motor setup than anything else.  Ever notice how a boat can be leaning or pulling hard to one side at very slow speeds or coming out of the hole or steering be extremely hard in one direction but start trimming up and that lean or hard pull starts going away.  Also how when a boat wants to lean left, how it's always worse with a passenger than when without.   This is caused by hull drag.

The sacrificial trim tab, mounted below the cavitation plate, is the metal fin sticking down in front of the prop. It's there to adjust the tendency of a prop to make a boat veer right when you release the steering. If it's aimed too far left it can veer the boat left less dramatically than untrimmed right veering, but at a particular speed. The other trim tab we're discussing, usually a set of power tabs that raise and lower, control the side to side roll of a boat. They are used to level the boat to compensate for a bad payload arrangement, and they raise or lower the bow. They play a large role in plane out speed and shooting out of the hole without having the bow raised so much it blocks your forward view. Tilt of the outboard controls that if you don't have power trim tabs.

Read about  prop precession and you will understand this phenomenon.

Simple put: an increase in angle of attack, (the bow rising changing the thrust line of the prop) increases the lift on the down side of the prop) causing the yaw to the left. Hydraulic steering does reduce the right pressure needed to hold the boat in a straight line but it will not stop it completely.

The simple solution: don't come off plane so quickly, or anticipate and apply right steering pressure.

Depending on the motor and prop you have you may or may not have a sacrificial tab. Adjusting this to a bit of right thrust will also dampen the precession effect, but it will not eradicate completely. Perhaps in your case this tab has moved a bit. To adjust it look at it as if it is a small rudder and move the trailering edge slight to the right. Test and readjust to your satisfication.
