    thermostat sleeve options

The one I am looking at now is an '87 V195 with a 185hp Mercruiser. From what I can find, it seems...

    Hello all, I am planning to go look at a 1987 Four Winns 195 Sundowner. The owner has said that it has a 165hp mercruiser with a alpha 1 outdrive. But the pictures he sent me clearly shows a GM "v" type engine. My understanding is that the 165 was a inline 4 cylinder? This would be my second...
