Help please - Sealine F42/5 Bilge Pump 4 location

[zaph]

Hi All,
On a recent trip in rough(ish) seas my bilge alarm went off and would not stop. The alarm panel indicated it was for bilge pump 4 at the bow of the boat. To extinguish the alarm I had to disconnect it via the circuit breaker on the main panel.
However I have been unable to find where the pump is located. The manual implies it is under the floor by the bow thruster battery box but this appears to be pump number three. The only location forward from this is down by the bow thruster itself however access to this is impossible without removing most of the bed in the main cabin.
Have any other F42/5 owners had an issue with BP4 and if so where is it located?
Any help will be much appreciated before I start taking things to pieces.

Thanks
Zaph

Hello Brixham Bound, I do have the user manual but it implies the bow bilge pump is under the floor panel at the foot of the bed in the master cabin but as I mentioned that is pump number 3. Pump number 4 seems further forward judging by the faint buzzing sound when I actiate it from the switch on the helm panel.

Hi Zaph, I've just purchased a 42/5 and have the same question. It seems to have 4 pumps however only 3 are included in the drawing. Did you manage to find pump 4?
