The Sonata class rules state that The outboard motor shall be provided with a stowage bracket beneath the cockpit—but what kind of a bracket? Here are some photos and a drawing (pdf) of a simple bracket that fits between the bunks and slides out of the way under the cockpit.
None of the dimensions are particularly critical. The most important is the 601mm. This dimension is measured directly from my bracket and obviously works on my boat. Check the distance between the sides of the bunks on your boat and subtract a few millimeters for clearance and use the resulting dimension.
The 535 x 127 cut out is for the outboard casing. My bracket has a rather elaborate cut out that matches the underside of the engine cylinder casing itself. I believe that this achieves nothing other than over-complicating the construction and adding weight. The drawing shows a cut out that would fit a Yamaha 5hp and probably most others. The 535mm dimension could be altered to suit your outboard.
As a suggestion, the 372 x 76 pad on the underside could be extended to the aft face of the bracket, with a stainless steel plate on the top face in the region of the outboard clamps to protect the wood.
