I have owned every major brand of outboard except a honda. All have their pluses and minuses. Currently my big boat is powered by a Yamaha. I am a giant Yamaha fan. The etech g2 may prove to be a super motor but to date they are a new technology. A repower is a large investment, as with all my investments I try to error on the side of safety. The Yamaha is a known quanity and you do a spreadsheet to calculate your expenses without unknowns. The other question is trusted dealers and service in your area? Last if you but a motor out of state it needs to be shipped to a certified installation service or dealer to maintaintain the warrenty. Best of luck!
