Found this when I was looking for a engine for new 2007 NR. If you can't guess I picked Yamaha
In June 2006 PB ran a heads up test on 150hp outboards. Although no longer in business, if you can find the report it makes for some interesting reading.
Just a little of what they had to say:Their words not mine
What We Found
In the drag race, the Yamaha (16.8 seconds) and the Mercury OptiMax (17.1 seconds) finished one and two, followed by the Suzuki (18 seconds), the E-TEC (19 seconds), the Verado (19.7 seconds) and the Honda (20.5 seconds). All of the engines were plenty quick for us. We did notice that the E-TEC had a slight hesitation before initial acceleration. In addition, it vibrated significantly at 2100 rpm.Conclusions
The E-TEC, with its vibration, hesitation out of the hole, and lower fuel-efficiency numbers in this test, doesn’t make the cut, either.
