Every time I order parts for my suzuki they turn out wrong. It is an 83' model EL50 and it says cabrea on the cowling. I figure it's just like a DT50 but I know that the carbs are different and the impeller I just tried to put in is too small to go around the shaft. The # next to the model is 05003 and the serial is 803383. Does anyone know what's different about this?<br /><br />On a side note when pulled the old one it had 1 fin left (but it was still kinda pumping). I recovered the other 4 fins but I couldn't find about 3/16" missing off the tip of one. How worried should I be about this- enough to start taking parts off to find it?
