Can anyone provide information on how to adjust the throws on a wheel system

The thtows seem timited to about 45 degrees to either side of center. I have tried different holes on the cable conection pin to the rudder, but either end up with more to port or starboard, but not to both equaly. Any sugestions where to get the manual if you do not know the model installed?

Try going to Edson directly thru their website or by phone...they are very helpful and will do what they can to help solve the issue...where was the pin in the rudder arm originally? You could also contact Arlyn as he has a lot of experience with the wheel steering and it's issues...Dan #747

Scott,
My rudder is also limited to 45 degrees port/starboard.
There is a rudder stop bracket on the transom that limits the turning angle.
If you remove the cables and manually move the rudder from the cockpit, you can see the angle allowed by the bracket.
Here's a picture of the bracket and rudder-control arm.

If the angle is less when the cables are re-connected, then you might have an adjustment problem.
The eye bolts are threaded and can be adjusted, but only are far as the bracket allows.
When installing the cable and pin, you should use the first pin position for best leverage.
It's also easy to install the cable and pin upside-down by mistake.
The left side is lower than the right side.
You can take up the slack in the cable to reduce the wheel play, but don't over tighten.
Also, the slack changes as the arm moves so test the wheel slack hard to port, starboard and wheel center.
Here's a photo with the cables installed upside down and with too much slack.

Let me know if you have any questions.

Russ,
Sure wish my bilge looked that clean. Guess I know what the next project will be. While yours has cables on both sides, mine has just one rod attaching to the stbd side of the rudder arm. I will check on the stops. I suspect that is the limiting factor. I did all of my previous sailing on OPB (other peoples boats)

and dinghies with tillers, so I am a little leery that this will give me the maneuverability I need. Any problems with the 45 degree limitations?

Scott,
I guess I jumped the gun. I should have asked if you had the 1-wire push/pull or 2-wire pull/pull steering.
I've heard of changes to the push/pull steering, but I'm not a good resource.

Anyway, about the 45 degree rudder angle.
I always turn the rudder and outboard together to reduce the turning distance when docking.
In the open water, I don't notice the rudder angle as being a problem.

What's your hull number?
I'm interested when the switch was made from the 1-wire to 2-wire steering.
Do you have any pictures?

I think it is kind of neat that my 250 is Hull#250.

Built in 1997. Thanks for the help.

I think the steering cable change from push/pull to pull/pull came following a temporary hiatis in offering the wheel steering option sometime around 2000.

I think by mutual agreement, Catalina and Edson decided the small boat steering system and the high aspect 2nd generation rudder were not happy together suffering too much warranty service. After stopping the option, Catalina set to redesigning a balanced 3rd rudder and Edson, a pull/pull cable system.

By 2001, I think the option was re-enstated with the pull/pull cables and the 3rd rudder.

I have it first hand from Gerry Douglas that Catalina blamed most of those problems on the beaching rudder being operated improperly in a raked back position. I tried to argue that it was the hold down design that was the problem but he wouldn't admit it, I think because Catalina had committed to dropping the beaching rudder and wasn't wanting to reenstate it.
