Ayuh,.... Welcome Aboard,..... Cadorette don't make the motor or drive, 'n yer picture is to small for me to see who's motor it is,....
It appears to be an OMC, 5.0l Ford motor,....
You should use the serial number from the motor to find a replacement,....
What's wrong with the current motor,..??
You can probably buy a replacement Long Block motor, 'n then swap over the accessories from the current motor,....
