Barry,
It depends on you. If you want to go fast, beat the pants off your buddy then maybe 115 is not for you. If you want to get places but are ok taking a little longer or you are going places where you will never hit WOT anyway (think ocean with 3+ footers), then a 115 will be fine.
The Etec will also give you more mid range torque, and with the 115 your fuel economy and oil usage will be excellent (especially if you use the Xd-100 oil and setting).
Go to http://www.evinrude.com/en-US/ and click on the Performance Reports tab, select the 115, and then the boat that's the closest to yours in terms of design and weight to get an idea of what you'll see for numbers.
