Old Merc Tips?

[my64]

I just bought a 1968 Merc 500 w/15" shaft. <br /><br />My questions are as follows.<br /><br />I was told it was a racing motor, that's why there is no alternator/generator<br />on the motor, how can I verify this?<br /><br />Do I go with the standard 50:1 oil/fuel mixture?<br /><br />On a 1964 13'8" glass runabout (about 600lbs) what would be a good pitch for the prop<br />or, anyone know the ?final drive ratio? <br /><br />and lastly, is there _anywhere_ I can get specs on the motor? (hp/torque/*** cc's|ci?)<br /><br />Thank You... This is my first boat & motor, I can't wait to get out on the water.<br /><br />tony

Re: Old Merc Tips?

As far as a racing motor, I would have my doubts. Mercury in those years didn't have a alternator/generator. There is a electronic pack on the right side of the motor tha tcharges the battery, but it's not that much of a charge compared to todays motors.<br /><br />A mixture of 50:1 is standard for Mercury.<br /><br />As far as prop pitch, I would start with about a 17 and go from there. If you have a tach, keep it in the recemmended rpm range.<br /><br />HAve fun with it and I hope that this helps
