Looking good mate just thought id check on your progress ,seems like your doing a good job.Is it your own design ? also while im no expert on airboats i still think your motor will run ok on that boat,sure it might not have the power of the others mentioned but it will get it moving just fine.I ran tame .46 nitro on an airboat my mate ran a powerfull one and his went faster but mine still went well.Just my thoughts on it mind .
