Centring the steering wheel

[hymerbeliever]

When I motor straight ahead, the steering wheel is at 9 o'clock, which is mildly irritating. I took the wheel off (thinking it would be like my old car and simply a question of repositioning it on the splines) but it is keyed and will only go on one way to the Ultraflex steering box. There are 9 or so Hex or Allen bolts around the wheel fixing it to the boss but they are too corroded to remove.

Is there any way of straightening it other than buying a new wheel.

Unfortunately marine helms just have the one keyed position as you've found.
You need to remove the steering cable from the helm then keep trying the wheel in different start positions as you re-insert the cable until its where you want it. Will keep you amused for hours. (Mine's twin cable & what fun that is.)
Don't forget to position the engine in the straight ahead position before you start the process!
