Hi All,

I have a 75Hp Merc, 4 cylinder 1986 model. Mercury also manufactured a 3 cylinder at the same time I was just wondering why they would do this seem strange. Is one meant to be better than the other?

Thanks

??--If you had a room full of 4 cylinder motors or if you have a shelf full of parts for a 4 cylinder design.------Would you throw them out?-----Or would you market them during the changeover?----Called ----" manufacturing management "----I believe.
 
If you ask the 'better' question, make sure you get the title of whoever answers....because it matters....bean counters take better to be cheaper which usually doesn't mean the same to the purchaser/user...
 
That's a lot of leftover parts spare to manufacture both engines for that time period. It would be interesting to know the different running characteristics. I know that Mercury was involved with Yamaha for those earlier periods and as Yamaha typically made three cylinder engines I was wondering if that influenced the decisions. Im guessing its also cheaper to make a three cylinder engine rather than a four cylinder.
