I have a 1971 omc tufm-19ex 215hp sterndrive , a rod bearing went out on my motor. I've been shopping around for a new engine to replace it it. I believe it has a 307 v8 motor in it. I want to know what engine to get to swap it. Do I get the same motor? Will the stern handle a 327? Or a 350? Will I damage the sterndrive with a high hp?
