Drilling Installation Holes In The Transom

The M8-Collector come with a laser cut wooden template
for easy drilling the holes on your transom, the holes on the
template will be match the installation holes on the base of
the drive, so, all you need to do is attached the wooden
template to the right spot of your transom and drill the
installation holes with 4mm driller.

It is recommended that the prop shaft centerline be
approximately 5 to 8mm above the bottom of the keel, or
above the level of the sponsons on a cat. As the Drive will
usually be connected to powerful engines, it is also
recommended that the Drive be offset to the right by about
5mm from the keel centerline on the transom to counter the
torque from such engines. Higher torque tends to deflect the
boat to the right when running, and offsetting the Drive
reduces or eliminates this effect, although it is also
impacted by the choice of hull and propeller.
