To sum up how a seaplane preflight is different:
- Watch for the float plane listing or tilting when you first approach it.
- Remove water from all compartments.
- Ensure drain plugs are in place and secure on floats or hull.
- Check your bilge pump is working if installed.
- Be cautious how you stand on the float when checking oil and fuel.
- Be cautious not to allow fuel or oil to drip into the water.
- Check water rudder cables are working properly and will not bind the air rudder.
- Check the rigging of the floats.
- Be very skeptical of a float compartment that yields no water when pumping.
- Check for propeller erosion.
