Thanks for the replies. I'll look into the rentals at Okeechobee. I was thinking about going down there for a day, as well. I used to live in the Stuart/Port St. Lucie area and haven't fished Okeechobee in over 30 years.
I did find a web site for a company that rents fishing boats primarily on East Toho and their web site says they will also rent West Toho. I'm still looking into them and could end up with a guided trip. I've got time to decide. The company I'm looking at is here. https://recreationalwatersports.com/boats/
Thanks again!
