Re: old evinrude
Look for a plate on the transom bracket for a plate with the numbers. Failing that, look on the powerhead for a welsh plug(freeze plug) about the size of a quarter for the numbers. The A115152 is a serial number. We would need the Model number to identify the motor. Tough on those old motors sometimes, as the plates are missing or the number on the block is painted over. Just look everywhere on the block if the transom plate is gone and post any numbers you find. If you can post a pic of the motor, that would be helpful.
