50-1
could you please tell me the weight of a 1980 mercury 80hp 2 stroke outboard motor
1980-81.
enough oil is what you need
oil ratio is 1% Pierre
56lbs according to nada pricing guide
Most likely its a 1980 I just called mercury on an engine that matched that same serial number and it was a 1980 the only difference is the last number was a 9. Im sure its a 1980.
The 1979 - 1980 model, 115 hp Mercury outboard, requires a 50:1 ratio. One pint of 2 cycle oil, to six gallons of fuel.
1980-1981 www.marineengine.com/mfr/mercury
For the 80 hp Mercury, you may use any brand of gear oil that has been blended for use as an outboard motor gear lube. There are many brands available other than oem, and are specially formulated for outboard use.
