I'm going with the ETEC, I've been posed with the same question to equip my up-comming boat build & had a Evinrude previously that was 28yrs old, thus when the lower unit went instead of repair, bought new a Suzuki spending the 1st year getting out all the bugs, then ran ok til' sold in fall, back to American built for me. This video made me feel pretty good about my decision. Could not get to upload, but is Youtube "ETEC vs Yamaha tug-of-war" Both same Boats w/150 HP proped the same, interesting to say the least.
