Hello all... Hoping to find some info on my old mercs. I have a 1969 125HP that has a great powerhead but the lower unit casing is cracked. I also have a 1974 Merc 115 not running but has a nice lower unit. Will the 1974 gearcase fit the older 1969? I am pretty sure they will swap but looking for a confirmation from someone who knows these old motors really well.
Also, will a blue band control box work on the red band motor or do I need a red band control box for the 69'? Looks like the male/female connections are the same on both motors.
Many thanks to all of the great people who contribute to this board!
