Looks good. Try to keep it out of the sun when not in use to extend the life of the plastic as it's unlikely that it has any UV inhibitors in it. Be sure to check the knobs periodically after installing the motor. Sometimes they like to loosen up. I suspect there will be an impression in the plastic which will help keep it in place
When parked at our place, the boat has a tarp over it - that covers the plastic. I do intend to check the bolts periodically - have cotter pins in the end of them so the nuts cannot get lost.
