I have a Glasstream 17ft. bass boat. I have installed new rack and pinion steering from wheel to outboard. When idling, if the steering wheel is released, it turns/pulls hard to the left. Under hard power, the wheel when released will turn/pull hard to the right. I've tried a trim tab with no luck. What can I do to make the boat track straight? :confused:

Re: Outboard Steering

It's a 1988 Mercury 115. Thanks.

Odds are it runs with the trim tab out of the water, and the prop either just under the surface, or slightly piercing the surface.

First, you should have put NFB (no feed back) steering on it.

You could have the prop shop put a bit of torque tamer on the trailing edge of the skeg. It would be a barely discernable buildup on one side, then manually file it back till it's right for you. It'll only be perfect at one speed but it'll help some at the others, sort of average out the setup.

One reason you need NFB is that if you should lose the helm at speed, hitting a wake or something, it'll tend to hook turn real sharp right now. If you had NFB steering, it would hold whatever position it was in till you got it back in your hand. It might be worth the while to change it out.

NFB has some majick clutches in it. You can move the steering with one finger at the helm. No force the engine would ever put out will move the steering. It has a funny feel to it, because the clutches take a 1/4 inch or so to engage, but the steering itself is so tight I can let go of the helm at 60 if I'm not dealing with wakes or something.

hope it helps
