hi fireman , your neck of the woods sounds much like our area here ,
lots of water , swamp , bog , rock , beaverdams , washed out roads and
grown over skidder trails , driving over 15 ft alders,
the engine is a very good one , but , always at least one but, the gas must be clean and fresh , i cannot emphasize this enough , use the machine regularily , or make sure the gas is stabilized , or drained from carb and tank , take this seriously.the axles do need attention , more they are greased the better , leaking depends on many things , used in water with a lot of sediment , sand etc the time to replace is shortened ,my exp. is when the axle or bearing , or seal , any combination thereof , i replace the entire assembly , axle will be grooved
seems to not last long enough to make the savings worthwhile , that being said i would still think 10 years or more is not impossible .
floats in about 2 ft of water, i have bilge pump, insurance? i cross rivers each week at least 75 yds 4 plus mile per current , stable and secure
