if there was a 70 eTEC when I bought my boat, I would have got that instead, but the new ( I think 2nd year ) Yamaha 70fla maxed out my 2012 competitor 165 tiller and was lighter or comparable to available 2 strokes... it has been a very good choice for me
"YAMAHA’s newly released F70 four-stroke marks a further continuation in the evolution of light, powerful and fuel-efficient outboards. According to Yammie, the inline four cylinder F70 is an enhancement of the Japanese engine maker’s popular F60. It shares the same displacement (996cc) and is only marginally heavier (10kg) than the F60. But the F70 differs from the F60 via its a unique engine design. Unlike other 16 valve engines, the F70 operates via by a single, not dual, overhead camshaft. This gives it a weight advantage over its competitors in the 70-75hp class and also increases performance. "
...other 4strokes now are lighter yet ... but if given a chance at the time, I would have gone eTEC
