This are the pictures of the console I have at the moment. The S4 console is, in my opinion to small for a 450, I've had it on my 2001 Vanquard 400, wich fits great. The S5 console on the DR 450 fits very well. The distance between the console and the tube is almost 30cm wich is more then enough. Maybe it don't look like much, but in reality, it turns out better than expected.
On what kind of boat do you wanne mount the S5 console?
If you want, I can make more pictures. Let me know what pics you need.
Maybe I have an small video from the boat, if I have it, I will post it on Youtube. I will let you know.
