hi i was told this motor was a 80.5 mercury 175 black max. i found a site(not american) and put the serial # in and it said it was a 79. is this correct and how reliable is this motor. it starts and runs strong (59 mph on water)but because of the age and not knowing the history other then the fact that it is very clean and appears well cared for i am wondering if during the winter i should just send it in to be rebuilt. i have a f4riend that said he would do it for around 1200. does this seem fair and should i do it or just keep running it as its not broke. the serial # is 5394565. hope to here from some one ....thx in advance, bill
