The RT188 is a nice boat and with your busy work schedule, you won't break the bank getting on the water for those precious non working days. Wind is a factor when tin fishing, but 24 volts will help ease the effort. The Opti 115 is a great motor. Oil consumption is not a bank breaker as you will be amazed how little it uses. That rig as described will make you smile each time you blast across the lake or sneak into a cove and work the shore.
