My ultimate plan (5 year) is to install an 8-10 hp kicker with electric start, tilt, remote shift, (Yamaha 704 dual binnacle controls or OMC controls) and steering. Only kicker I know of that has all of the remote electric stuff is the 8 horse Yamaha high thrust 4-stroke. I know, Geek prefers 2 strokes!! Don't know of a 2-stroke with all of the remote stuff. Yamaha 8 HP 4-stroke weighs between 80 and 90lbs. Alittle heavy, oh well. If I install a kicker, my 24 gallon tank will be for it and the 60 will be for the main engine. The added weight will probably cause me to modify the engine well, increase engine well scupper size, and raise the control and electric access through the sides of the engine well. Another option is a bracket and close off the transom. Check out this article which is a detailed installation on a Whaler.
