I bought my last Mercury 4 stroke - once it's off warranty and you have a "Serious electrical burn out" and nearly a "Fire" your out of luck with Mercury Marine.
I wanted to 'buy American' but they gave me no choice an I will buy Yamaha or Honda, better product !
Etec has my vote also, fuel efficient and quiet.Starts first time everytime and trolls for hours with no loading up.Evinrude got it right with service also, no hassles.
