I am going to make a few sets of jack plates that fit the new S550/GT350. They will sell for $130 shipped. You have your choice of powder coating in red or black and they come with grade 8 bolts and install directions. Just beware that they are harder to install on the S550 than the S197 as the pinch weld is now hardened steel, instead of just high strength steel. A regular drill bit will not work. You will need a good 5/16" bit (or two!). Cobalt or carbide. This is the bit Black Boss used to finish drilling his holes with.

If you want a set, just send me a PM as I am starting on them next week. Mike
Here are the plates being used on a Boss.
