Most 4/6 cylinder inline Mercury outboards used the same lower unit from the early 70's to the mid 80's,however the gear ratio changes with the higher hp models. 80 hp and 85 hp inline 4 used a gear ratio of 2:3

Are you sure the 8 isn't a B?

Re: 80 hp blueband Mercury

That is a Australian serial number and it should be a 1976. You need a unit off a 4 cylinder motor in the following hp's: 65/75/80/800/85/850 as they are all 2.3:1 ratio......

Thank you all for your advice, no all I have to do is find a secondhand unit.
