Two fuses for the washdown circuit?

[Boatagain]

On my ‘16 C30 LE, the circuit for the raw water washdown is fused in two separate places. One is a 20a spade fuse located in the PDP fuse block in the cave. The other is at the cockpit switch panel for the pump where there is a built-in fuse holder for an older style glass tube AGC fuse.

Is it necessary to have two fuses in this circuit? The cockpit switch fuse holder on mine got so corroded from weather, that it became inoperable (the fuse didn’t blow), so I temporarily bypassed it. I’ve ordered a replacement switch/fuse panel. Does anyone happen to know the amp rating I would need? The corrosion is so bad that I can’t get the fuse out of the holder to read its size!

Thanks in advance!

Anybody?

The wash down fuse corroded up on my R25 as well. Replaced it with a new fuse holder and a 10 amp glass fuse. :mrgreen:
I pulled the spade fuse to keep it from turning itself on inadvertently when the switch gets bumped. I only put it back when I want to use the pump.

10 amp! Thanks! Good idea about the spade fuse.

Had the same problem with the fuse. Cleaned it up, replaced the fuse and coated the insides with dialectric grease. The super lube from Harbor freight. It protects from both corrosion and moisture.

Very strange. Just did this today. Yes two fuses in the line. I replaced the Johnson pump unit including switch and fuse. The fuse in this assembly does not seem to be able to be removed. I like the idea of disconnecting the 20 amp fuse when not in use as it would be quite easy to inadvertently kick the pump on.

I made a small plastic c-shaped bushing from a plastic washer that slides behind the switch. I drilled a hole in it and tethered it to the water outlet so it does not get lost. I just pull it out to make the switch functional. I also made one for the cockpit lighting that always seems to be accidentally turned on when using the stern door.

It’s little things like this that make this board so wonderful and life a pleasure. What a great idea! Thanks Mike!

Similar to knotflying I made several of these “keys” out of several glued layers of thin strips of teak. One for each of the rocker switches on the boat that I don’t want inadvertently turned on. I’d post a photo but I am not at the boat.
