this is a first timer here, I used the searches, but to no aveil. So you've heard it before, <br /> What year is my motor? <br />Mercury 110 9.8 HP (Lighting)2cyl<br />Serial number 7103018<br /><br />some casting numbers 74818 837-6476 <br /> 133 stamped twice, must be the assemblers #s <br /><br />I need to get a manual, any good connections?<br /><br />The motor is only firing on one cylinder and I suspect the brain box (# p/n 339 5287A3), due to the rotting and fraid wires...or the coil is toast. any good connections on parts? kev3
