seems to be some slight performance advantages as far spark timing and a little hotter coil.needed? not sure, maybe just the latest and greatest for a couple more bucks.

you shouldn't have to change anything other than the exhaust pipe to the transom plate. Either transom plate has the same dimensions, check the spread of the motor mounts with a tape measure, they should be the same. They standardized most of the transom assembly back in 84. As far as timing goes, run no more than 5 degrees initial, I can't remember what the total was, but they had a service bulletin saying to set all the 3.7 to 5 initial. While you have the point plate off, check the advance weights and springs.

Spare you were rite , Checked the spread on both Transom brackets mounts and they are both 9 1/2 inches . That makes things a little easier ! The reason i thought i needed to swap them was that each bracket has a different configuration at the top .

they added two bolts somewhere along that time
