Not sure what goes on with the warranty, since they dont make etec anymore.
That would be my biggest worry, parts(not the warranty so much).
The 25/30hp were real nice, abit heavy but no more then the 4 stokes at the time.
Sorry cant help with price, used stuff went crazy high since covid...seems to be getting alittle better lately. If parts are avaible and theres someone(or yourself) capible of doing repairs,in your area(if needed), $3500 isnt a crazy price.
