And I can't wait to use that as a chapter heading in the forthcoming ops manual, but I've made further mods to the pontoons specifically to support the power-plants, and the easiest way to drop and re-fit a pontoon is with a car-jack.

Simpler in fact, now those tyre bays use pneumatic drives to over-tighten the nuts.
Anyone beside me figure they're in cahoots with roadside assistance?
