There are many different style of solenoids.
Over the years Mercruiser has updated and changed some of the solenoid designs.
Don't be surprised if you get your new solenoid and it looks a little different.
Make sure you turn off your battery switch before removing your old solenoid.
Take notes as to what wires attach to which terminals.
Some solenoids use the mounting bracket as a grounding base so make sure
the contact areas are clean and rust free for a good ground connection.
The best way to buy a solenoid is to EMAIL us with your engine serial number.
You can not buy a solenoid just by it's "looks" and never install an automotive type solenoid
or you could cause an explosion resulting in damage, injury or death.
