Sea water in bilge sump.

[Vara]

Bummer, found 1.5l of salt water in sump.

Checked all possible points of ingress, all dry.

So tomorrow rather than my usual routine of pretending to do boat maintenance, while drinking coffee and doing the crossword, it's all sole boards up and an in depth dig about.

When that happened on my last boat, it was the O-ring on the log transducer, allowing an almost imperceptible dribble of water into the boat. I find kitchen roll is great stuff for checking for presence of water.

Try that blue paper you get for wiping stuff up - it shows the water more than white.
Oh, and our last leak was the secondary (manual) bigle pump not having a high enough swan neck and water came in when the boat heeled enough in westerly winds.....

if you're sure it's sea water then the stern tube is often a culprit. Might be worth checking the fresh water tank, mine leaked and it took a long time to realise it, with the usual frustrated sweary language!

another goody is a small fracture in the engine exhaust pipework, don't ask how I know, took ages to find the little begger!

Still puzzling, not engine or stern gland based as these have a separate bilge. Not bilge pumps as they exit just below gunwale, and as I is a gentleman, they are never near the water!
Poss culprits now under review. Kitchen roll a go-go.

Don't you love boats? I thought I had a slightly overweepy stern gland which I had tightened, only for the next time out the injection elbow to blow out... Obviously rust isn't very waterproof... Never the thing you suspect first

Boat ripped down to component parts and no sign of source of leak, getting fed up.

scant consolation, found my favourite 8mm socket and a pack of cable ties, lurking in bilge.
