I've tested it and it's all working well, I'll give it a clean up and see what you think.
If want to take a look at it and see it working (and have a coffee), give me a call, or I can bring it along on Thursday, it won't break the bank.

I might be able to help with a fixed VHF.
I've got an old (hence pre DSC) and tatty Seavoice RT550, as far as I know it's all working well, I'll test it tomorrow and let you know.
As can be seen from the photo, it needs a bit of a clean up.
I wonder how long the "New Beach" will last, or the small bay east of Hamworthy Park.
It looks as though any current will now bypass it and it'll silt up.
I think there could be a problem with the festoon type, as the LED equivalent does't radiate light in a continuous arc.
There have been a few threads on WSF on this subject, if I can find them I'll post a link.
Fishfinder and GPS won't draw much current, but the pump will probably be the problem.
What type of pump is it, need to know the max current and how long it's likely to run?
As Rob said, is it seawater or fresh?
If fresh:
Do you have a fresh water tank onboard? If yes, could it be overfull and the motion of the boat causing it to come out of the breather?
