I own a 2001 Super Air Nautique ,so far,still in good shape and condition, even had fighting many times to fix the issues:
1) water go inside cylinder due to loss exhaust flapper and wave hit the stern,
2) over heat due to raw WATER PUMP fail, fix by bearing and water seal replace (never impeller fail),
3) starter broken due to lanyard intermittent so starter broken due to too frequent start on the sea,
4) overheat again few years later ,no parts fail,fix by cleaning all the raw water passage related parts,
5) can't run the engine continue,due to no fuel on tank,anti siphon valve stuck,and fuel RELAY strip down,
6) key pad fail due to moisture and water go inside, fix by surgery the rubber,clean and solder PCB,
7) milky ENGINE OIL due to riser water passage broken ,fix by replace it and change oil few times,
8) propeller and shaft ,rudder, struct toast by hit the earth , replace it,
9) idle surging and high ,when throttle to neutral will stop engine ,fix by replace fuel pressure regulator,
10) engine not smooth running,knock sound heard from inside engine,when pull throttle to higher speed vibration feel, figured out loose of the hall effect sensor (stator) inside distributor,temporary fix by silicon glue,it runs great !
hope these can help some body in puzzle.
