Here's some assorted notes on different seaplanes. Hope it helps, after all the less we know the more we do :-)
weak link, requires lots of care and maintance
main gear cavity flodded when on water so gear submerged when 'wet'
even when maintained failures are common
scarificial landing strip on bottom to allow very safe wheel up landings on land
said belt cheap and easily replacable
float cost $750,000
minus 7-10kt speed with wheels out
