You can look up the year on the maxrules site, by serial number.
Depending on the year, it will be a 2 liter or 2.5 liter 60* V6 motor. The engine is of a proven design and is still in production, although with an updated ignition system.
I'm cornfused. The SN would indicate about 1987, which would be a 2-stroke antique. Sure, proven design (if you're into Mercs), but "still in production" - I thought they haven't been made for 30 years or so. Or, are we talking about parts availability?
The site I was on shows only 4 strokes made now.Didnt even show the optimax.Maybe their like Yamaha where 2 strokes are still made just not for n.a. market and Europe I believe.
The current Optimax shares the same block as his carb'ed 2 cycle motor. That motor was made up until Merc stopped production on carb'ed and EFI motors, likely in the 2000's. Production on that motor started in 1978.
I have looked all over cannt find ser number listed single my first mercury ob it was completely overhauled last year but don't know any thing about it thanks for help
