does the boat veer to the right while going straight? Or is it hard to turn the steering wheel for a right hand turn?

On your lower unit above the prop there should be a fin pointing downward, this is a trim tab. It can be adjusted one direction or the other a few degrees to counteract steering torque. If your steering pulls to the right then adjust the tab a few degrees to the right as if you're looking at it from behind the boat.

Is the motor plumb, and square, and level on the transom? Are the motor mounts good?

If'n ya cain't dial it out with the torque tab I'd start looking there.

If your motor is lifted and tab is out of water at high speeds, you can try one that attaches to your skeg.

Dave and others put on a NFB steering system and removed his adjustable tab, with out any torque steer issues.
I installed a Baystar hyd. steering system on my CV16 and don't have any torque problems.
Can you post more info and some pictures of your boat and set up ?

I think a lot of it is just the nature of the beast. The lack of power steering is probably the biggest killer. My CV16SS has always pulled. You can adjust the trim tab to help some but it will always want to turn if you let go of the wheel. After a really long boating day my arms are pretty tired!

Jason, you need to look at my mod for power steering I did on Phoneix.

Trim position of the engine will also affect how your steering pulls. If you have the engine trimmed all the way down it will pull to the right. Trimming it out will help equalize the steering forces. But you need to adjust the trim tab for best average based on your engine trim at cruising speed. Post a picture of your lower unit so we can see just what engine/drive unit you have.

Not certain if outboards are different from I/O's but my 16ss had lots of pulling, this is what I had to do.  My original skeg was bent, couldn't tell by looking at it, but when you really che Ked, you could see it.  It cracked when I tried to straighten it, so I cut a part off and put a skeg saver on.  As for the torque tab, it's trial and error.  Depending on trim and throttle it may pull one way, then another as you increase speed.  I spent a day on the lake and was able to set it so it was perfect 3500-4200 rpm.  At that speed I could let go of the wheel if I wanted too.  At WOT, just a slight pull right.  Boats that pull hard, and to lock if you let go of the wheel are dangerous, insure your killswitch works.

For relatively low $$ the NFB (no feed back) steering is a simple upgrade.

It has a mechanism that locks the steering when you are not inputting a steering command.

Turn and loosen your grip and it stays in the turn, go straight and loosen your grip it continues to go straight.

You can still feel that it is harder to turn left than right, but the boat will not spin out of you let go - intentionally or otherwise.

I consider it a safety device.

My torque steer went away with a prop change too.
