hi all, i have a leak coming from the hinge whare it bolts through the Perspex and down to drip on the bunk.
there looks to be 2 sizes of gaskets to fit different sizes of hinge, both similar shapes but slightly differing dimensions, does anyone out there know what size/type the hatch is so i can get the correct gasket for it.
its on a 2006 bav 33 cruiser.
thanks

as sy posted but add to check exhaust elbow, a pinhole in the raw water to exhaust manifold would let exh pressure into the system. before it gets bad enough for your coolant to escape.

Hi, I've got a schematic which more or less shows the changes I made to the default setup.

Some remarks on your plans.
As said, such a large battery system with relative small chargers (both engine and shore chargers only have a max! of 50A) will take more than 12 hours to recharge your batteries. I'm not sure the standard charger will be able to deliver this.

If you do not want to fix a solar panel, you could invest in a portable solar setup. If you are not able to create a special connection for that, you can look for those portable versions you can directly connect to the 12V accessory outlet. You would be limited to max 150W then, but it could compensate for half or a third of your consumption.

As symphony mentioned, such an amount of energy does not make sense in my opinion. It will take 12h + to run the engine from empty to full. The size of your dc-dc charger seems ok. Your alternator will not deliver 50A at engine idle, but needs approx. 1500 rpm to generate the 50A without overheating. The usual way to design a lifepo system is:
1) Calculate your average daily consumption (sum of runtime of each item in hours x current draw in Amp). Start with your fridges, autopilot, nav instruments, ..). Fitting a battery monitor in advance to know your demands in helpful to avoid costly stranded investments.
2) This demand has to be produced somehow (shorepower, altnator, ...).  Divide the result of (1) by the max current of your charging device, and you roughly know how long you need to run it every day...
3) A sensible battery capacity is 1.5 to 2 times your daily energy needs. If you can't or don't want to produce your electricity daily, increase your battery capacity by the amount needed for each additional day without production.

Maybe one or more of the following issues:
Not enough raw water flow, raw water circuit partially blocked,
impeller ripped,
filter clogged .
Thermostat not working.
Head gasket blown.

Bavaria 30 Volvo  D 1-20. Engine running fine for 2 hours then overheat alarm. Coolant forcing its way out of expansion tank. Clearing very hot. Raw water circuit working normally with water exiting the exhaust and exhaust temperature sensor (i fitted) normal. Any help gratefully received

Here is my boats power-electric system schematic (individual small loads connect to house bank main distribution bus bars). I drew it up in Miro, cant export a higher resolution with the free account. Is going to change a wee bit, but functions so far (I see the windlass is not wired up here, but I have it connected to the main LiFePO4 bank. I have three large lithiums in parallel and they can give out a stable ~400 A, which is way sufficient for windlass action which I have fused at around 250 A).

Taking on board the advice given on this forum and elsewhere, we have decided to go for a 10kg Lewmar Delta.
For those that may be considering going down this path, we can report that the anchor fits on the bow roller and doesn't obstruct the lid on the anchor locker.
We did notice that the shank is a tad taller and this results in the anchor sitting slightly more forward than our old CQR. This is due to the bow roller locking pin. Otherwise no issues.
Many thanks for your input.
