Australian mini airboat build

Hi I’m new to air boats and have been interested ever since I was a kid I’m after so advise or direction with building one I have a 51hp Rotax 462 with a reduction box and three blade prop and I also have a 10x8 flat bottom tinny ( I think you guys call them Jon boats :razz:) and I’m wondering if it will work as a airboat

Sounds fun

Hello and welcome to the site !! To be honest I think the combo is a little mismatched...You need a bigger engine or a narrow hull...The 8ft wide should be a few feet less for 50hp...Will it work ??? Yes, but you might not get the performance you're dreaming about...
