Toe in or Toe out
 

So I'm researching how to set up my tie bar and I keep seeing everyone reference toe in or toe out. Is this from the leading edge or trailing edge of the drive?

Sorry for the stupid question, but this is my first twin engine boat. Right now I have it where the trailing edge of the drives are 1/8" wider than the leading edge. Is this toed out because the propshafts are wider, or is it toed in because the fronts of the drives are closer together??
btw my props are spinning out.

Thanks for the help

Good question
:food-smiley-007:

This would be the correct discription. Think of it just like your cars wheels.

i think you have it right, under power the drive's will flex in with the prop's spinning out, thats how i set mine anyway. i think its toe-in that way.

That's correct (slight toe out 1/8 - 1/4") ASSuming your props are turning out. Because when they turn out they cause outward torque of the drive "heels" when running at the upper end of the speedo. The torgue then in theory straightens out the drives. If that makes sense?

Think of the toe as the fat end of the drive or bullet end....like your big toe....:p....or looking forward your toes are up front, heels aft.

The problem when I've adjusted, is getting the drives exactly straight with the tie-bar disconnected, then making the in/out adjustment exact for both drives from the center point. Typically there's a little dot or scribe mark just above the transom plate used to mark dead center between the two. Then you have to assume your transom plates are mounted perfectly vertical from the bottom of the boat. Then there's the wrestling with the drives against the hydraulic pressure. Lots of trial and error.

But probably if you nail it, you could very well get a better return on your efforts than screwing around with prop tweaking, and it's cheaper too...Good luck.

If you are in a single engine outboard with a right hand propeller and you let go of the wheel which way does it turn?

If you were a tree, what kind of tree would you be?.....:p.....Sorry, couldn't resist.

I would say since assuming you mean the prop turns clockwise when looking forward, that the boat would veer right.

Veer left if prop turning left/counterclockwise looking forward.
