Fuel tank leak

Is that farmer towing away his new chicken hutch?

It did surprise me that they had a tractor....it had Beneteau written on the sides...
Anyhow...that was the busiest boatyard I have ever been to...vehicles wizzing everywhere...literally not a safe spot to stand anywhere

How is the diesel getting into that well, it looks sealed (dammed up) at both ends?

It's either coming through where the cable exits directly at the bottom of the V section or more likely at the top of the V from under the tank which won't be sealed to the moulding.

Well...that is the mystery from the beginning...for a start...that is a very shallow bowl below the engine...when it overflows the diesel pours aft a couple of inches and goes into the keel, below the shaft.
However...on land the boat was a little more lower in the bow...this caused, somehow, the diesel to flow forward then fall under into the keel...kind of forward, down, back..
Don’t forget...you are seeing less than a liter...I’ve pumped out and disposed of 60 - 100 liters
 
Anyhow...next the tank comes out...either by the end of today or Monday (they close on the weekend)

Yes I wondered about that cable but could not decide if it went through the bulkhead or was just resting against it.

You are talking about where the diesel may accumulate but first it has to go into the space under the engine and I think that is what the question was asking, how does it get there?

I suspect it's not a solid rib or bulkhead but just a part of a moulding with the hull or keel space below it. I am assuming that the cable goes through it to some transducer or instrument elsewhere.
 
Nobody can get information from the Beneteau factory of exactly what the anatomy of the boat is below the the tank and engine, not even their main dealer can prise out this information

Maybe it's just a space with the hull beneath it and that moulding bonded to the hull, if that is a cable going through the moulding and it isn't sealed diesel will have gone into whatever is under the moulding :eek:

Hopefully they will find wet diesel on the top of the moulding under the tank, does that cable go through the moulding and if it does what is under the moulding and what's the cable for?

I don’t know...also don’t forget there is I believe, cooling water going to the coupling
