Rudder Tie Rod Adjusting

Bottom Line · Post by **Bottom Line** » Jul 12th, '06, 10:52

I am ready to connect the tie rod to the tiller arms with new tie rod ends (swivel sockets). Is there any "trick" to adjusting the length or is it just trial and error until it fits right? Thanks.

You need to "toe in" the rudders, i.e. have the front edges one inch closer to each other than the trailing edges.

I wish I had taken a picture but I would swear that mine were set with the trailing edges about 1 inch closer. Does it make a difference whether they are toed in or out?

Mike,

Either way makes no real difference to the handlng of the boat, but with the rudders wider at the trailing edge makes a better "blue hole" of clear water behind the transom when trolling... Also it gives you a bit tighter turning radius.

Capt. Patrick: Good point. Any trick to adjusting or is it just trial and error in getting the length right?

Mike,

With the tie bar not connected to the tiller arms, but connected to the ram, turn you steering wheel to adjust the ram to dead center of its travel.

Set your rudders admidship and add the offset. Hold the tie bar above the tiller arms and adjust the connector ends to correspond to the tiller arms. This should be just about the location.

Hook everything up and turn the wheel hard over each way, marking the maximun travel of the rudders. Re-adjust as needed...

Cap't Pat..

In reference to my Bertram 33.. with oversized rudders (rectangular blades, with some balancing area area forward of the rudder posts) how much would you suggest my rudders be out of parallel alignment. Above is mentioned 1" at the forward edges, but different rudder blade configurations would probably need different distances.. is there some angular spec you are aware of? We are discussing this subject presently on the Bertram33 site.

Guy,

There is probably little or no difference in the settings between different designs and sizes of rudders... Just don't exceed 1" of total distance between the trailing edges and the distance between the leading edges. 1/2" would be the minimum difference.

Thank you for the above.. but just to be sure I am correct.. I assume when you say....

"Just don't exceed 1" of total distance between the trailing edges and the distance between the leading edges."

That you mean that the total distance S+ plus P+ is more than 1/2" and less than 1" than the distance S- plus P-.

I hope I don't seem nitpicking here, but it seems important to be sure of such small dimensions, since it appears that a small error here might have a significant effect on the overall handling of any boat.

Guy,

Yup... Run a tape from trailing edge to trailing edge. That will be between 1/2" - 1' greater than a tape from leading edge to leading edge. Each rudder is offset by the same amount, or 1/2 of the total offset.

Patrick

Thanks Cap't Pat.. You da man!

Capt. Patrick: I got the tie bar on and it may need some minor tweaking to get it just right but now another question. There seems to be a fair amount of "play" on the bar in that it swivels quite a bit on the tiller arm balls. I'm talking about a fore-aft swivel. Is there any way to tighten this up?

Mike,

There's two ways you can tighten the tie bar from sloppin' fore and aft.

1. you should have a threaded hole on the connector ends, opposite the end that fits onto the tiller arm. If you don't already have a square head lock bolt there, they are usually 1/4"x20. Position the bar vertically and drill a dimple into the tie bar, then install the lock bolts and tighten them down.

2. Have a couple of large nuts re-threaded to 3/4" NPT and put these on ahead of the connector ends. When everything is re-adjusted, tighten the nuts hard against the connector ends.

There will still be a bit of play but the tie bar won't flop back and forth.

Patrick

Capt. Patrick: The connector ends do have the square head lock bolt. I tightened these down. The bar is not swivelling inside the connector ends. Rather it is piviting back and forth on the tiller arm ball because there is a cut out where the ball is inserted into the connector end.

Mike,

In that case you need to tighten down the large slotted retainer cap screw to remove the excess play. Inside each connector end there should be a spring, a plunger plug, then two SS 1/2 collars, & the retainer cap screw. The body of the connector end has holes to accomodate a cotter pin.

When it is adjusted correctly there should be no side to side play between the connector end and the ball joint of the tiller arm. The cotter pin will line up with the slot in the cap screw, securing it at that adjustment point.

Capt. Patrick: I'll try that adjustment wehn I go to the boat Saturday. Thanks.

2006 right!

I need new springs any suggestions ?

Keith,

You might be able to match them up on Amazon...

Mcmaster Carr would also be a place I would look.
