Mercury Marine produced the Black Max outboard engine series primarily during the 1980s and 1990s. The specific last year of production for the Black Max models was around 1996, after which the company shifted focus to newer engine technologies and models. These engines were well-regarded for their performance and reliability during their time.
The last Mercury Mariner was produced in 2010. Mercury Marine, a division of Brunswick Corporation, ceased production of the Mariner brand when it discontinued its outboard motor line. The Mariner name was used for various outboard motors and the last of these models were phased out by that year.

To determine the age of a 50 hp Mercury outboard motor with the serial number 5684541, you would typically need to refer to Mercury's serial number database or contact a Mercury dealer for specific information. Generally, Mercury outboard motors have their production year indicated within the serial number, often related to the last two digits. If you can't access that information directly, checking online forums or resources specific to Mercury outboards may also help identify the year of manufacture.
I run my 150hp mercury V6 on 50:1 pre-mix (fuel to oil) this has been working fine for the last 7yrs! Your engine will be the same if you wish to pre-mix. This equates to 0.5 liters of oil in 25liters of fuel or 0.8pints in 5 gallons. This is very a very common practice where I live, as the Mercury engines are prone to thermostats corroding, then overheating which causes the oil pump drive to shear, loss of lubrication and then seizing!

The serial number 9414679 for a Mercury 50hp engine indicates that it was manufactured in 1982. Mercury Marine typically uses a system where the first two digits of the serial number correspond to the last two digits of the manufacturing year. Therefore, the engine would be from that year.
