Default Steering problems!! Boat pulls to the right.

When I drive my boat at any speed in forward gear it seems to want to steer right. When at cruising speed there is probably a 10 lb force of pressure i have to hold against to keep the wheel straight. The trim tab on the motor is straight and the skeg isn't bent hardly at all. Why would the boat keep trying to steer right. If I were to let go of the steering wheel when on plane the boat would turn all the way to the right abruptly like jerking the wheel. This is kind of scary and tiring. I don't know what would cause this or if it is normal for an older boat (1988).

Also when I try to back the boat, all it will do is turn to the right. I can turn the wheel full lock to the left and still the boat will turn to the right and spin in circles if given enough time. This might help out describing the problem.

The boat is a 17ft fish n ski with an 88 evinrude 90

The trim tab isn't meant to be straight. It is supposed to be angled somewhat to counteract prop torque or the pulling to one side. Look at other outboards and you will see how much they are angled.

Not sure about the reverse problem. The trim tab shouldn't have much effect in reverse.

Loosen the trim tab just above the prop and move the back of the tab out to the right about 15* .

Your reverse problem is caused by the pitch of your prop. You've got a ski boat and its propped accordingly. Great prop for pulling a skier out of the water but not much good in reserve other than stopping forward motion.

Plan ahead.......

Move your torque tab so that the trailing edge is at about 1:00, maybe 1:30....

Sound like you have single cable steering. What you are experiencing is something all single engine boats do. Because most of us have hydrualic steering, we are unaware of this. Adjusting you torque tab may help but with singel cable steering it will probablt not eliminate it. dual cable steering would help, hydrualic would eliminate you feeling the pull at the steering wheel.
You can also add a torque tamer to the skeg:

???

I'm thinking it needs to be at about 4:00 or 4:30 as you are looking down while standing right behind the prop. Are you thinking that you are under the tab, feet toward the front of the boat, looking up?

To the OP; mine did exactly the same thing. Moving the trim tab fixed it quite easily.
