General Info: FP Solimar steering, LAVEZZI &others how to lock the steering wheel

[CaptainRivet]

Hi all,
How can you lock the steering wheel on the Solimar steering that all FP cats Athena, Lavezzi, Tobago, Belize.. have. Saw the Solimar on several models.

I just have a quick fastener where you can dismount or mount the steering wheel but I see no way to lock the wheel on my Lavezzi. Is there a part I can order from Solimar, looked in their catalog but cannot find anything suitable.
As Lavezzi has the props after the rudders it is very important to be able to lock the rudder if you go in reverse so the rudder doesn‘t bang into full lock.

No lock that I have ever seen. Never had a problem backing down unless you are reversing at speed, the helm stays where you set it. I find it quite useful to to use the helm to vector the prop wash when mooring stern to in a cross wind

Looks like I need to make my own lock, badly needed.
Lavezzi has the props behind the rudders, different cup of tea then Athena.
2nd I have 2x50hp with 18“ props instead 2x20hp with 14“ ones, the pressure on the rudder when reverse is quite high, especially if they are not centered. They then slamm to one side and done that several times the rudder will get out of center and you have to realign the steering new.
