Just bought two Evinrude Fastwin 15s. One decent but with scuffed paint, the other a parts motor minus carb and tiller and painted a garish blue and white.<br /><br />The decent one runs well. Serial # 15014-13735. Seller told me it is 1958. Has pressure tank.<br /><br />Any pointers? Never used pressure tank before and would appreciate any hints, tho things seem to be ok right now.<br /><br />I paid $280.00 for both motors and pressure tank full of fuel. Was this a fair price?<br /><br />What oil/gas ratio should I use?<br /><br />What is year of motor?<br /><br />Thanks guys
