Replacement solenoid for Bob’s Machine jack plates with standard series pump (Flats jacs, Ultra light, Std Extreme, etc)
This solenoid is the “new” style that has been in use since September 2012. If your jack plate was made on or after that date, this is a direct fit replacement.
If you have an older jack plate, you will need to purchase the solenoid upgrade kit, as this unit will not fit onto your old pump backing plate.
You can find the solenoid upgrade kits here :
