Ive been looking to Rent a fishing boat on One of the lakes on the Kissimme chain but i haven't been able to find any. They either only rent pontoons or its a guided fishing trip. Does anyone know some place to go?

A company called Butler Boat Rentals provided rentals at Toho, but their website isn’t clear anymore whether they are only renting on the Butler Chain or other lakes as well. 
 

You could also call Mark at Toho Marina, and ask if he knows of anyone renting boats on the Kissimmee chain.
