Re: Stus-List Voltage / Amp Hours
Some good answers so far. I used to sell and install those things and they ALL have issues. We'll start with basic principles. You can get a meter that keeps track of current in and current out. Kind of like an odometer that rolls forwards and backwards. The current out part is only semi-tricky. Amps X Time = Amp/Hours. If you use 100 amps for one hour or 1 amp for 100 hours, you used 100 amp-hours. Peukerts Law (https://en.wikipedia.org/wiki/Peukert%27s_law) screws this up. 100 amps for 1 hour takes considerably more out of a battery than 1 amp for 100 hours. The various meters have different ways of accounting for this, but none of them are perfect. Some have preset constants for different battery types and some have learning functions. Either way, errors add up and eventually your meter is way off. Current in is much worse. Charge current can actually charge the battery, heat it up, or boil off electrolyte. It has to go somewhere, but that somewhere is not always stored electricity. I could put a constant 1 amp charge on a battery for 500 hours, but that does not mean it gained 500 amp-hours. It could have gained 5 and got slightly warm instead. Knowing when to stop counting - when the battery is topped off - can be very tricky. Bottom line is I found you have to reset the meter every so often to bring it back to reality. If you are on a good charger all week, chances are the batteries are full and you can reset. If you use 100 AH out of a 400 AH bank and the batteries are at 11.9 volts, chances are they are beat. Joe Coquina C 35 MK I ___ Thanks everyone for supporting this list with your contributions.

I was headed North towards Kent Narrows and saw what looked like another 35 MK I headed south. The AIS said she was "Mr Bubbles", so I gave a call and got an answer. She is a 1972 35 MK I from Rock Hall. I told them to sign up for the list - hope to see them here. Joe Coquina ___ Thanks everyone for supporting this list with your contributions.

I assume that your 450 Ah is a nominal capacity, but you don’t know how much of that is left. The 6 A you mention, is it 6 A over several hours (let’s say 3), i.e. 6 A times “several (3)” hours = ~18 Ah or just 6 Ah?

Re: Stus-List Toilet Replacement
Just read this before heading out for a quick sail to pickup the prawn trap... and the head started acting up! Seemed to have lost prime on the seawater intake. At first I though it was plugged, but it was just sucking air. After a few minutes, I finally got it going again. No pleasant as the Jabsco replacement has a nasty habit of pumping air back in the bowl and spraying water everywhere, so keep the lid down! Anyway, probably not much help to you, but the label on the cabinet indicates the original was a PAR (I think), and the Jabsco seems to fit ok, although only 3 of the 4 mounting bolts line up. Not sure if the PO had to drill new holes or not. Given the cost of rebuild kits (~$100 CAD) vs a new toilet (~$150 CAD), if this problem happens again, it's probably time for a new one, or I will consider making a composting unit fit. It seems the holding tank vent line is shared with the vented loop vent line, so when flushing, nasty smells fill the bowl as air is drawn from the holding tank. Possibly the vent through-hull is plugged... next thing to check. I have spent more time on the head than any other item so far, and would gladly say goodbye to the whole mess if a composter would work! -- Shawn Wright shawngwri...@gmail.com S/V Callisto, 1974 C 35 https://www.facebook.com/SVCallisto On Sun, Jul 7, 2019 at 8:25 AM Raymond Macklin via CnC-List < cnc-list@cnc-list.com> wrote: > Hello: > > I have a 1985 C 33 and i am looking to replace the manual toilet.

Re: Stus-List Toilet Replacement
Ray, I’m sure it was a Wilcox-Critten. I had the same issue and the Jabsco doesn’t work with the way the studs are on a #@. Luckily I still had the old toilet and was able to clean it up, get a new seat (West Marine for $66-YIKES) and re-build kits are still available. If the old toilet is gone or beyond rebuild, you may have to resort to eBay, or other Internet places that have “used” ones.
