Electric start on a portable outboard is an unnecessary luxury. Unless you have problems using your arms (in which case I would advise against running a tiller skiff) it adds weight (starter motor, extra cranking battery) and a potential failure point (have seen an e-start gear get stuck engaged to flywheel). I have it on my 25 Merc and have yet to use it. I can start mine with two fingers and a half pull. Don't let it influemce your decision. The E-tecs are great motors, most of the guides up in Alaska where I worked ran them. I prefer 2 strokes to 4 strokes mostly because. I like the smell, sound, and top end, but Tohatsu makes a great motor too. I also prefer to run a premix two stroke (albeit less efficient) because I don't want to hinge catastrophic failure on an oil pump. I think either would be a good choice- also consider weight, although the Etecs are heavy for two strokes.
