tiller motor pull

8 posts in this topic

Like someone mentioned in an earlier thread, I also have a hard pull to the right once I have my motor past half open. I have an older 75 Merc tiller motor. It pulls so hard you almost need two hands on the tiller control. Is it as easy as adjusting the screw above the prop and adjusting the fin below like someone recommended I try? Any advice would be great!

Yes try and adjust that tab above the prop. Also make sure it is very tight. I had one loosen one time and lost it when driving WOT.

I've got the same problem with a 2004 Mercury 25hp tiller. I have adjusted the skeg some; does a guy do a big adjustment or should a little do it? I have increased the steering friction which helped some.

Thanks.

Well, mine did pull right, but I bounced it off a few rocks, a tree, and a concrete slab in the river, and now it tracks so straight I can let go while driving WOT and it keeps right on going. Just lucky I guess.

I'd go for a bigger adjustment to see if that helps... otherwise you'll end up monkeying with it for a while to find that it's something else.

The other simple thing is making sure, after your hole shot, to trim your motor up to the point where there is no resistance. My 75hp tiller will pull when all the way down but when I trim it up I can get it to a point with absolutely no pull whatsoever (I could let go of the handle if I wanted to). I thought I would mention this as a friend who always had a counsol boat did not know this when he drove my tiller.

A big adjustment would be a 1/8" to 1/4" of rotation. It doesn't take much to make it run straight. Take a Sharpie and make a mark where your starting point is and then make a mark at the new position. That way you'll have an idea how much you've adjusted it if it needs some tweaking the next time out.

BTW, you'll want to turn the trim tab in the clockwise direction (when looking up at it) to eliminate the pull to the right.
