I used to have aq kicker boat too, and I replaced the bearings 5 times to every greasing on my airboat trailer.
Wet loading/unloading, especially after a bit of a road trip, is just asking for bearing failure. I've had buddy hubs, greased with waterproof grease, you name it. If it goes submerged when its warm it sucks water AND condenses inside. Any long term boater knows this. Its nothing to me as long as you want to its your boat and trailer.
My only point was "I" will go elsewhere where "I" dont have to put "MY" trailer in the water. I think this satisfies the Airboaters Creed.
