2 person jon boat: power to move the boat

Postby steveca4@hotmail.com » Sat Oct 13, 2018 9:50 am

I plan to build a light, strong, two man, 16' x 3' jon boat, to weigh out at approximately 80 to 100 lbs at most.

I will need to build reinforced rear deck area to support the motor, prop and cage.

For me speed is not a big issue as I'm going to be in marshes and small lakes/rivers.

What would be the smallest motor and prop combo that would move this boat at a 3-5 mph over lilly pads infested fresh water.

I'm a complete novice when it comes to thing air boat related so practical information is what I seek.

thanks

From a practical standpoint, 16x3 would be a canoe, not an airboat hull.
Any engine that would be operationally satisfactory would produce enough torque roll to turn it over.

Why so narrow? There must be another consideration that you've not shared.
As described, almost sounds more like submarine plans rather than that of a boat.

Look at a Monark hull. Might be a bit wider

If it's only lily pads and veg, get a longtail mud motor kit and a 13 hp predator engine, put it on a jon boat. A lot quieter than a fan. If you build an airboat do it right and get a 7'+ wide hull and at least enough power to run dry ground. THAT is what an airboat is for!
