I am looking at a used boat (18ft) that has an older 4cyl volvo penta inboard motor. Maybe 15 years old, older fisherman had it and swears it was one of the best motors made. I am getting it checked out at Custom Craft marine. Any opinions on these motors? Reliable? It looks basically like a Ford Pinto motor. I had one in a Ford Courier and it was great. Does 110 HP sound about right?
