Gimbal housing install

[Jbasham]

Looking for the drawings/manual for the mercruiser gimbal housing installation, like the bolt pattern and hole sizes for the transom. I have an OMC Cobra but the pattern is the same. I've seen it posted before but can't find it anywhere. Thanks

Thank you. The factory install manual shows the keyhole cutout with dimensions. I really just need the hole sizes for the 6 mounting studs and the steering arm clearance notch dimensions...

This says Volvo Penta, but the Merc cutout is the same.
