considering you said, "its a blast", then i take it, you've taken ur out to the water already, and seemed to you, it performed like it should. So..only "maintenance" i'd perform on her, is, locate the black caps ontop of the motor, remove the clamp ring, and expose the bellows underneath the caps. Then remove the 2-allen bolts, securing the housing to the motor, and remove the unit. There are a valve under each, threaded to the inside of the bellows. You want to clean those about every 50hrs or so.....Only other thing i suggest you do, is remove the dropgate/reverse bucket and nozzle assy on the back of the boat to expose the "cone", and rmove the 3-8mm bolts securing it to the venturi. Nasty smelling oil will pour out, which then, once drained, re-install the cone ,with the setscrew facing up top, and remove that screw to refill the cone assy with 75/90 syn oil....:cheers:
