Electric bilge pump on Moody 38

[Hippohay]

Hi - we want to fit an electric pump on our 38CC (1996) and have been told by the yard it will need a new outlet run and thru-hull fitting. I'm a bit reluctant to start drilling new holes in the hull. Would it not be possible to tap into the outlet pipe beyond the existing manual bilge pump? And was a run/thru-hull for an electric pump not fitted at the factory? We've only just bought her and I've only spent a short time on her - but I'm sure I saw what looked like a water outlet pipe in the port lazarette.
Any advice appreciated.

My dad and his mate fitted an electric, (Rule), bilge pump to Rogue in 2003, (I bought her in March this year). The bilge water comes out of a hole by the starboard lazarette, (I assume that is the big locker almost on the stern?). The outlet looks like an original fitting.

Spoken to Jeff.... He cut the manual bilge pump pipe just in front of the bunk in the aft cabin, (behind the gearbox), fitted a Y junction with non return valves, and joined the pipe from the new bilge pump there. The biggest part of the job was feeding a wire from the bilge pump to the switch panel, the switch being conneted directly to the battery from the panel.

Hope this helps, and I also hope that it was the right way to do it!!

Cheers

G'day Hippohay,

Provided the existing outlet is large enough to cater for both pumps to be running at the same time no problem.

You can avoid the non-return valve by raising the pipework above the the 'Y' joint and not have to worry about it working or not.

I've been thinking about this on my M44. I was going to sacrifice the battery venting pipe and use that for the electric bilge pump, so it would be the same distance just with the exit on the port side.

However, I have been warned that the total distance plus the rise would make the electric bilge pump incredibly inefficient. How does your one perform?

I've never monitored it as such but, when I run it manually, it sucks until there is no water left, (well, only a bit), and it doesnt run back in.

I've also been stood on the stern and seen water being pumped out in reasonable volume... so it seems to work OK on manual and automatic.
