hi andrew, thanx for the questions
there is very little flex on the rear linkages, due to the fact they are very short in length, about 2 inches unsupported length.
the motor is bolted to a metal plate , the plate on the opposite side from the motor has a circular recess in it , this houses a o-ring , th eo-ring gets sandwiched between the motor plate and bulkhead A , this is done by 4 small studs protruding from bulkhead A, and using nuts you draw down the motor plate onto the O-ring, with a small touch of grease to help sealing.the motor plate also houses the rubber spring lip seal , which holds back the water, i`ll try and get a picture of it rather than explain. much easier. as wonwinglo said, a picture speaks a thousand words.
