Hi Scott. Would that be a factor in the 80’s and 90’s ? We had 140 versions of the v4 here from around 84/85 up to around late 90’s I’m sure. Had the 130hp too. Most common was the 115 version…but I’m also aware that likely half of these or more, were probably upgraded to be about 130/140hp by dealers. Amazing engines I think.probably doesnt pass emissions
