Re: Mercury 110 9.8
Serial number is not freeze-plug stamped on older Mercs, rather it is actually stamped into the block itself. It'll be a 7-digit number, stamped into the upper rear of your motor block in about 8-point type...<br /><br />I've got a few 1968-1969 red-band motors (4, 9.8, 20, 35 & 50hp) and I consider them to be solid runners - if you take care of them. A few things to look out for - leaky lower units, particularly at the upper driveshaft seal, located in the base of the waterpump housing. The driveshafts are carbon steel and will rust, particularly in this spot creating a rough sealing surface. There are fixes for this. I rather like model 110 - very quiet and lightweight...<br />- Scott
