With respect to the USS Squalus, Thresher, scorpion

I have water in the boat. Getting tons of water in Karla.

Sun roof drains running clear , check..

Door seals maybe?

Coolant level ok. Vacuumed two gallons out today.

Well that is hard to miss. Only in back foot well? Wet seats? Pranked by the Ford truck up the street?

Dry seats. I’ll check three sunroof drains.

No signs of water thtough door seals.

Stumped.

I,ve never had a functioning tailgate washer. does the waterhose to the rear run in the car or under the car. I don't think there is a separate reservoir, right?

Wet at front and back or just back (as per Volvolugnut)? Are the door drains clear? Are sure the left rear door is not sloshing around.

Door seals can leak between the seal and the door, but I have only had it on the front doors about the level of the door mirror.

How was the car parked when the water came in? Was it on an angle?

Have you checked the drains by the fuse box under the cover are clear?

Sunroof drains can fracture near the edge of the sunroof 'cassette' at the corners. But if you had those leaking it would give evidence of the leakage into the car through the headliner.

We got inundated with a real ocean rain storm while I was overseas. The Admiral told me it was coming down 4-6 inches per hour.

Current working hypothesis: Maybe the sunroof drains got overwhelmed and I’m just cleaning up the leftover

It stinks of coolant too , as,y residual heat exchanger leak left the foam with residue.

Coolant level rock steady in car.

Update

Came back from a week travel and rain.

Made extra effort to get sunroof closed and level. Car is dry inside.

6 inches of rain and water in the boat again. Looking at door seals I have something going on here, not right.

there is a piece of plastic trim out of place on the LHS rear door that might be re-directing water into the cabin

Caulk sunroof shut, and rear doors. You only need the fronts.
