Would like to hear opinions on the mechanisms offered by MG and MK - I fish in very shallow marsh in SE Louisiana and often need to temporarily lift the motor up somewhat but continue to run it to get out of tight spots; this is hell on my back. After two back surgeries I'm looking for an assisted/automatic system that will trim the motor up and down for me. Could you tell me if the available system allow this (as opposed to being either fully stowed or fully deployed) and what you think the advantages/disadvantages of the MG and MK versions are? I currently run a 74lb Maxxum on my Ranger 521 and it has been great.
