I am looking at a 40 mercury tiller. 1996. Tiller. Its on a skiff i want. Might keep it. Might not. Anyways do they have reliability? Its a 4 cylinder. I thought most were 3 cyl?? Supposedly has low hours. I have been seeing a lot of hells bays with them. But probably newer engines. Should I stay away from an older one? Whats the resale like on it? If i switch to a good ole evinrude.
