You would need an SE206, but I cannont tell the gear ratio from the serial number. You will need to count the teeth on the pinion gear, 14 teeth is a 2.00 to 1 and 15 teeth is a 1.87 to 1. You might be able to call Mercury to get the gear ratio.

after talk to mechanic, said the radio is 1.87.
part # 1647-9148 T 86.

do you have it avaible this part to buy?

That part number comes back as being a counter rotation drive. We do not make counter rotation units at this point. Do you have a twin engine setup?

Thanks,
