Rudder Position

The rudder not being in line with the shaft line would not cause it to go round in circles. As long as the rudder is parallel to the shaft line the boat will go straight ahead. Most modern twin shaft / rudder designs today have the rudders set slightly inboard of the shaft lines.
The swirl around the intake pipe might have more effect. But nothing you can't correct with the trim on the TX. Doug 😎

Liking the advice on the pick up tube Doug 😁
I'm thinking an attempt at moving the rudder stock may be an idea as it is fairly off centre and the photo doesn't really show it well. if I ever get to the point where i get it in the water I wouldn't want it going round in circles lol

Learning so much more with each reply to my posts. One day I may have a boat in the water 🤔

If I were you I'd leave them alone until you know how the boat behaves.
Most important is to shift the prop shaft forward until the prop is about half an inch forward of the water intake. i wouldn't worry about the intake pipe, not worth the effort.
If you want to move the rudder stock you'll have to move it forward or back a bit to ensure the drill for the new hole doesn't constantly try to slide into the old one, whatever it's filled with! I would drill it out until you can epoxy glue a tight fitting wooden dowel into it.

Rudder Position

I'm after some advice on rudder position in my ever tedious restoration of a crash tender.

After some great advice from DaveM and Doug I actually 'bit the bullet' and removed the old IC Engine Mount and lessened the angle of the shaft which will hopefully make motor alignment easier.

I removed the rudder bearing tube and water pick up for ease of access whilst re positioning the shaft and then noticed the rudder and pick up were not centrally positioned on the hull.

On looking at the plans for the 34" Crash Tender I found that the measurements of the rudder and water pick up tubes were also not positioned correctly.

I am now presuming that I will be need to re position the rudder as a priority and possibly the water pick up?😤😤

Any advice on this one would be much appreciated from you the experts😁😁😁
