Where the SMC55 NAUTIC cannot be mounted from below using the M8 bolts and
lock washers supplied, it is possible to mount the drive from the inside.
NOTE! Remove the stainless steel screw thread holders from the drive feet with
an M8 bolt and nut before drilling out the holes.
The system can be secured from the inside if sufficiently long M8 stainless steel bolts
are used. With this installation method you will need to ensure that the galvanic
separation, provided by the plastic feet, remains intact.
