Now that was funny.
Oh surprise, another knucklehead who works at West Marine giving out blatantly ignorant advice. Next time you are in there please ask him what his qualifications are to have said that? Probably a retired proof-reader at the M&M's factory. "Damn another typo W&W."

Ask him what the short circuit current is a 100Ah Northstar battery is, you know the ones WM sells. Now ask him what the short circuit current is for four of them in a house bank? Then ask him if he thinks 4 GA wire shorted can handle the current from a shorted 400Ah battery bank....

On second thought, forget it... This guys is so cluelessly ignorant he won't get it anyway.....

Back to West Marine. Once I discovered that a joker valve is $80 and the bottom seal/flapper is another $20 - and a new entire flush unit is only $109, I went with the new unit.

I was a seriously nasty cleanup - but we got the new unit in and we're back in business.
The joker valve is not designed nor intended to overcome improper plumbing... If your holding tank could back fill the head you have an improperly plumbed system..

You need a high point and 1.5" siphon break between the head outlet and tank or this WILL happen again.......

Always cheaper and easier to buy and install an entirely new $hitter.

Glad that one failed on you at the dock and not at sea.

Re: 1989 Hunter 40 - A million questions.

Okay - per the above feedback, I've started cleaning everything up. I got the negative busbar in and moved everything over then got all the negative cabling squared away on the house bank and the starter battery...



It's definitely looking a lot cleaner - but I still need to get the positive cabling finished up. I've ordered more +/- cables to ensure that I've got the same gauge throughout and that it's all marine-grade - and that all the old-nasty stuff (except for the negative from the engine and the negative for the panel) will be gone..

And now the LinkPro seems to be locked in...



However, in testing the difference between what I'm seeing on the LinkPro and what the multimeter is reading on the actual batteries - I'm seeing a difference of about .5-.8 volts (the LinkPro is a bit higher). Is that normal?

Now that was funny.

We also got the companionway screen that the boys helped build in place and it rocks...

Re: 1989 Hunter 40 - A million questions.

Maine and Miti are of course right(and I also add my note of thanks to them for the expertise they bring) yet as a fellow owner of a 25 year old boat pragmatism forces me to agree with you Smack.

There are definitely things on my boat that are less safe than they should be yet I aim at all times to try and make everything as safe as it can be.

All of my boat issues were likewise inherited problems, yet the joy of boat ownership is such that the moment Iolanthe became ours and I the skipper they were instantly all of mine to solve and the consequences of not doing so mine to live with.

I guess it is about prioritizing.

Except of course Eric Kaufman prioritized as well...

He spent quite some time and effort methodically installing self steering (A Hydrovane, the quote for ours was 6k) something very commendably bluewatery yet as a keen observer pointed out in the forums he had also just done a 'quick fix' on his hull deck joint that may have played a significant role in his boat's undoing at sea.

I wonder if he just did the 'quick fix' because he ran out of time trying to perfectly and professionally install his Hydrovane?

FWIW I ignored my most of my messy 12V wiring for a good year and instead spent money/time on new seacocks, new rig, new lifelines and meeting ISAF offshore safety regs We went cruising and did ok so we were either right........or lucky.

Yes - the ACR will allow the start battery to get any current it needs.

Next on the list is engine overheating, which is 24% of fires. Fuel leak is only 8%.

I think we're probably talking past each other here.

What's in that report is essentially what I said in my post...that electrical fires are followed pretty closely by mechanical fires (such as engine overheating), fuel, etc. They are "right up there". So I understand the percentages, I was just saying that these things are at the top of the list...which they are.

In any case, that's not the point I was making regarding Maine's comment. So carry on.

Re: 1989 Hunter 40 - A million questions.

In my time on a 20+ year old Navy submarine we have quite a few fires. They were 100% electrical and none were cables or connectors. They also 100% put themselves out once the breakers to whatever it was tripped and the "fire" went out. Meanwhile with all the holes in the boat for seawater there was only 1 minor case of flooding (wouldn't have been an issue if we hadn't been so deep at the time, which we weren't for long).
