The bracket will be bolted between motor stringers and the middle part is ready to accomodate shaft thrust bearing. The central hole shall be drilled bigger (the shaft will be 25mm).
The back side of the bracket facing the motor is reinforced with ribs to avoid bending caused by the shaft thrust. Probably overkill but one never know... the lenght of the bracket is 60cm, material is 5mm steel. Next step is to hot dip galvanizing.
At the end this was not used due to the lack of space. So no axial bearing is in and it works just fine.
