Motor Pulling to One Side - Any Advice?
Hello All,
Have had this problem for a long time, and over the years have somehow accepted it, but after heading out yesterday (and feeling the pain in my arm!), I think it's time it got fixed.
I have a 1989 20HP Johnson tiller. While motoring, the outboard "pulls" to the right side. So, during operation, I have to "strong arm" it to keep it straight, causing for a sore arm after any extended trip. Unless it is going at it's slowest speed (and I take my arm off the throttle) it will stay in a straight line. Anything higher and it just swings over to the right side. Weird, as moving the motor left or right seems to have the same resistance and to the left doesn't feel any "slacker" than shifting it to the right...
I've searched for something to tighten, etc., but have come up empty handed thus far. Any advice? Simple fix?
Thanks in advance for any help...
Good Fishing,
Justin

yeah... there's a very simple fix.... there is an adjustable "fin" (don't know what its called) right above the prop... usually all that's needed is a 1/2" socket to loosen the bolt that holds it, you adjust the fin in the direction to compensate the direction its pulling, re-tighten the bolt and away you go.... its that simple... I am sure that if you googled it... you could likely get lots of pictures of just how to do it.

Thanks, guys - much appreciated....
Just went outside and had a look at the motor. What I see is a lead-coloured fixture that sits horizontally on the right side on the plate directly above the prop. It is approximately 1" by 1/2" and has two bolts holding it from the underside. I assume this is it?
Cheers,
Justin

You have been given great advice here, also fyi that lead coloured piece is a sacrificial anode to reduce corrosion as well as a trim tab.

Thanks, Terry - had a feeling that it was an anode protector of some sort, but since it didn't have a "keel" on it, had no idea it had anything to do with steering and trim...since it is only raised approx. 1/2 inch.
Will let you know how I make out.
Thanks again, all...

I suspect that what you have on your motor is an anode only and not a trim tab at all.
On some outboards this is combined.
The anode / trim tab is normally circular, with a fin and a single bolt allowing it to be rotated to achieve the trim or direct the water flow from the prop.
An anode only is usually a rectangular shape with two bolts, it is oftem machined to have fins to increase the surface area, but may not be located anywhere near the prop.
You should still have a device to adjust or trim the motor though.
If you can give us make and model number I can try and look something up for you.

part # 39 is what you are looking for if it's adjustable on your motor

Is your motor pulling when you are on plane?? I was told that if it is, it is not that little fin over the prop. cause that fin doesn't touch the water when you are on plane. The way I fixed the pulling on mine was that I got the motor installed at the right height. Cavitation plate level with bottom of the boat. Now when I am trimmed out I can let go the steering and it'll stay in a straight line.
