On my boat, this pump turns on with F3 button. 

I was using it, and then I think I blew the fuse. The F3 light flashes now and I cannot find the fuse location.  

Any help??

The fuse is 30amp and is on the outboard end of the We panel. PM me your email and I will send you the PDF showing the fuses on this panel.

thanks Wayne!! 

Yep!  I see it now after reading your message and taking a closer look!  It’s buried in the middle of the board!  I had to move the wire bundle to see it!

Thanks a million!

Another reason to replace fuses with the "glow when blown" variants.     MUCH easier to find and replace.

I sent the WURTH 12V diagrams I have to your email account.  Hope they help.

This is the reason why I have replaced all fuses by resettable ones.  I once lost a fuse I had to change and it disappeared into the Würth panel and caused a short circuit on the PCB. This was a 1000€ silly mistake.

The F3 pump is also a problem.
It has a rubber propeller who can not run dry.
Besides if it stay off for a long time the propeller locks and the fuse blown.
After having changed several fuses I took it out and replaced with a grey water pump.
This can run dry without melting the propeller.
I also took out the filter as this pump does not need one.

The throuput is lower but you can rely on it when you need it.
