Wish I could take a pic for you, but it's at the weekend house. Let me know if you want a pic, I can take it next weekend.
It's very easy to remove, but I just leave it on in case i need it. When I said I haven't towed anyone, I meant another boat...but I wouldn't hesitate doing it.
It's all SS, so the differences in galvanic potential between the bracketry and the outboard bracket (I assume to be some aluminum alloy) are minimal.
I wouldn't go custom cause these swiss engineers have already done all the design work...why get someone to do a one-off design? It may or may not work or fit as well.
I looked at a Scout ski pylon that a Scout dealer had ordered for a customer but they changed their mind. He offered it to me for $500 (way below retail) just to move it. I didn't like that it mounted to the transom, I would have had to drill 4-6 holes in the transom. The surface area of its brackets was nowhere near the surface area of my 150 Johnson OceanRunner's brackets. I think that you're pulling from the engine brackets with the turboswing is the most unique feature...doesn't seem like it would stress the transom as much as transom mounted ski-pylons.
But then again, I'm not a structural engineer...but I did stay at Holiday Inn Express last nite
