I'm gonna build a jon boat airboat . I was gonna run one 22hp preditor . My question is . If i put 2 of them in tandom spinning one prop . I should beale to double the tourque and spin much more pitch on the prop ???? I'm don't care about speed AT ALL . Where i go there's no open water , just THICK swamps .

Wow, there’s a few thing mentioned that may be a concern.
First; It’s a narrow Jonboat with reduced payload capacity and lateral stability. You’re increasing the weight aft with two power plants. Second; designing and building a drive system and synchronizing the engines for one output shaft. It’s more complicated than an adequate single engine. Third; Propellors, and all airfoils, have minimum and maximum angles of attack limits and exceeding them will result in not producing lift or stalling. Too much pitch will stall a prop and the airstream will be rotational instead of rearward. This will cause a craft to roll.
Keep it simple; keep it reliable.

cajun,
Go back to the cat's original suggestion. You are describing a hovercraft opportunity
. Otherwise, just keep humping it
