of that drive is very straight-forward and it can be mounted in any position.
1. Be VERY sure to provide it a solid mounting base - a bulkhead is best, and any shelf or bracket you fabricate must be bullet proof and able to take lots of force. Much more force than you think.
2. Make sure you stay within the maximum mounting angles for the drive.
3. Make sure the rudder
stops are set correctly so that the drive does not bottom out before the stops. Many boats have wide rudder
stops, but this drive requires 35* stops, so yours may need to be repositioned inward to be within that angle.
4. Provide good heavy wiring
Those are pretty much all you need, and just a summary of what is in the installation
