You can start by applying slick bottom to the bottom of the hull and goto a carbon fiber and or warp drive prop. If none of that stuff works, you might have to get a bigger motor......

Got a Tach on it?
How high is that engine turning up when it's stuck?

It takes LOT of power to run green grass even with a small boat.
Frog spit or steel flex will help.
I ran a 13 foot Kennedy with a 125 Lycoming ground power for years. It ran the hiil better than a lot of more powerful boats, but it had poly on the bottom.
It had a 66 * 34 stick prop. turning about 2700 RPM's.
Rules: Stay out of the green dog fennels, black muck, dollar bonnets, and white beach sand. Believe me I have been on all of it, and it don't work.

2Stroke - First, be sure your engine is up to snuff mechanicaly, then you might opt for an adjustable 68" prop. The adjustment allows any airboater to tune the whole package to optimim performance.
