Hi, I'm Kyle with Stern Pinball and today we are going to go over how to remove the boat and shark target assembly. To perform this service we will need to remove the glass from the pinball game. We will need to open the coin door. We'll want to unlatch the lock down bar from the cabinet using the two latches on either side of the coin door. Take the lock down bar and set that aside. It's always a good idea to shut the coin door when you remove the glass so it doesn't come out and scratch on the edges. Once you get the glass out, make sure you put it down somewhere soft and gentle. Once the glass is removed, we have the coin door open, which puts the interlock switch in its powered off state, which removes 48 volts from the playfield so it is safe to reach inside. We want to remove the pinballs. The quick and easiest way to do this is to locate the ball serve plunger which is attached to the end of your ball trough where all the balls live. You can grab that plunger and push up on it and it will kick one pinball out. We'll want to repeat that five more times until all six balls are out.

If you're going to just remove the boat target, you do need to lower the shark target down into its lowered position. To do that, we'll need to use the service menu. To lower the shark target, we need to have the interlock switch pulled into the service position. The playfield lights will come on. Enter the service menu by pressing the black button until you see Go to Diagnostics Menu Hit the black button again scroll to the right using the right red button until you reach game specific tests then select shark motor test Once in this test, you can use the left red button to lower the shark target below the playfield. Once you've lowered the shark target below the playfield, press the interlock switch in to remove the 48 volts from your playfield. And to perform the service, we're going to want to have the playfield in service position. You'll grab it here in the middle of the apron, pull up, grab the service rails, pull it forward until it stops, and lift it up and against the head. With the playfield up, this gives us the ability to remove the wiring harnesses and auxiliary things around the boat and shark target assembly. They don't need to come out together. In this video, we're going to remove the boat and then we will remove the shark. To remove the boat assembly, we will need a quarter inch nut driver and a three-eighths inch nut driver. The boat target is affixed to the playfield with these two studs that have these nuts on the underside and a screw on top. The first step to remove the boat target is to unplug the wiring harness going to it, which is this one here. Depress on the locking ramp and pull them apart. We'll take our 3-8 inch nut driver and remove the nuts on these two studs here.
