I have acquired an Evinrude with the following stamp RPH 0432160. So I take it as a replacement power head. It has 235 carbs and crossing some other part numbers it appears to be a 1985 model. Is there a way to look up the RPH number to determine what type of power head? I there a good way (and easy) to verify that it is a through-and-through 235? Again, the only model/serial is the RPH 0432160.
