I don't want to seem rude second guessing you Backlash, but I find the second serial number closer to ~1969. There's a quick way to be sure; if it's from the '60s it'll be a 9.5 instead of a 9.9:<br /> Under the cowl of a 9.9 <br /> Under the cowl of a 9.5hp <br /><br />Peanut - can you post the model number from the 9.9?
