Torque steering
- Thread starter pubillos
- Start date
Interaction between motor angle, boat load, throttle position and boat attitude.
Can be adjusted away to a great extent with the little tab on the bottom of the cavitation plate above the prop. But the setting will be good mostly under the conditions for which it was set.
NFB is nice. Allows you to steer the motor from the helm but the motor can't steer you through the helm. If you let go of the wheel it'll stay where you left it. If you go into tilt or trail lift, motor won't flop over from where you left it.
But it will not eliminate the torque steer. You still want to do the adjustment. We put Teleflex NFB 4.2 on our V20 Wellcraft with 150 V6 Evinrude. It was very nice, but the 4.2 turns was noticeably slower than the standard 3.0 turn ratio. The 4.2 is suggested for V6 outboards.
A little one-way clutch in the helm is what allows the NFB feature to work.

All the above is true BUT. Prop torque can be tricky to dial out. One thing is, the tab on the motor will be pretty inefective at high cruise and WOT. If you are running at over about 40 MPH you might want to consider a "Torque Tab". It goes on the starboard side of the skeg at the trailing edge and takes out the pull to the right. They can be screwed on, pop riverted or best is to epoxy it and fair with Marine-Tex. Then trim the motor running position for max performance at WOT and see if it is running straight with equal pull in each direction. If it's pulling left now, grind the tab down a bit and try again. Still pulling right, you may need to raise the motor an inch or 2. 1 bolt hole up is about 1 inch. Be sure you have a water pressure gage to be sure you don't get to high and lose pressure.
NFB steering, and hydraulic, by far the best, will mask any feedback from your engine and prop to your hands, which is not necessarily the best situation. You won't know what it's really doing until you try to turn in both directions. It takes "seat time" to really get it right and really get to understand what's happening.
