I have inherited a seized evinrude lightwin. I have the power head completely disassembled. I am new to outboards and am wondering how to ascertain the year and horsepower rating for the motor. I would also appreciate some insight into whether parts (pistons,gasksets,etc.) for this motor might be available. The numbers I found on the powerhead are 3502a and b03228 1.<br />Thanks in advance for your expertise fellas. Michaelj.
