I'm a new owner of a 2008 330 express. Can anyone tell me where the fuse for the power assist pump is? The manual describes it by the batteries. Others said by the pump, so I pulled the panel, found the pump but no fuse was found. It happened right after I was using the windlass and noticed very low power. Right after raising the hook the power steering went away. The battery looked horrible so I installed a new house battery so that's not the issue. Any idea's other than the pump just went out. Thanks

Can you see any connections in the wires going to the pump, where you can test with a volt meter? If there is power, even low power, the fuse is not blown, although you still want to locate it.
If near the batteries, the fuse might be an inline fuse or it could be a breaker like the ones with a button.
I am not sure if your problem was coincidental or happened as a result of using the windlass. It is possible that you have a bad connection somewhere. The first thing I would look at is if there is power at the pump. If you follow the wires at the pump, you should be able to find where they connect to the harness. There may be two connectors on the pump unit. One with two heavy gauge wires is the feed from the batteries. The connector on the harness should have 12v or so across the two wired pins in the connector. That 12V usually comes from the battery area and should be switched by the main battery switch.
The second connector on the pump should be the control signal. That should have 12 volts on it when the motors are powered ( they don't have to be running). That wire should be a smaller gauge. If you have juice on both connectors but nothing happens when they aye plugged in and power is on, the pump may be bad but it could still be a bad connection. To tell you need to measure the voltage when the pump should be running. That can be tricky depending on what type of connectors are used.. I am basing my suggestions on the assumption that you have a Seastar power assist pump.
Try selecting the BOTH position on the battery switches to see if that makes a difference.
By the way, does your windlass still work normally?
The windless works poorly. May be a worn or corroded motor. Yes as far as I can tell its a seastar power assist surrounded by a 100 other wires behind the holding tanks, fun. I'll continue the search. I'll try using 1 & 2 batteries. I just repowered and ran it down from pompano to marathon and the steering was great. It just seemed to go out all at once.

Assuming its a Seastar Hydraulic Power Assist...There are some variations in models but they never have a fuse at the unit. The fuse is at the power source end of the wire.
Some came with inline fuses and some just had ring terminals to connect to a breaker/switch. The connection could be at the battery with an inline fuse or on a breaker near the battery or your other breakers or the +12v House breaker or on a Positive bus bar somewhere. Follow the gray wire.
The PO may have added it or it may have been added by the dealer. there isn't necessarily a "Grady" way to connect it.
Looks like this model pictured has a wire to the key switch to turn on/off with the engine.
