The Espyville/Causeway Marina is a wonderful place to rent boats. Not only do they have a wide varity of boats but also has some of the nicest boats on the lake. The owner (Sarah Juracko) and all the employees are a kind group to rent from. It is located right in the middle of the lake,so if you wanted to go to either end of the lake it is very close.  The prices are very reasonable and you get your first tank of gas for FREE, which will last for about 4-6 hours full throttle. What a deal! They also offer overnight rentals and fishing pole rentals.  They not only rent boats there, but they also have food. This is good for when you come in from a hard day of fishing.
