I would like to add to my question about Bilge pumps. that in my RAF style launch, the water ingress problem has stopped
One, as i filled the mainshaft tube with vaselaine, but probably more so, that i sloshed clear varnish around the inside of the hull in all compartments, let it dry, and did the same again,

I now as of today, have NO water ingress at all,

I used a hydro switch and a 3v-6v pump at 3v. Mounted the switch 1/4" above the pump pickup. It comes on when the switch gets under water and goes off when the water is out. So far has worked perfectly.

Thanks for the replies,
I did think about a windscreen washer pump, and am running a 3s lipo,. so 12v on tap,but overnight in my dreams (weird ones) i used a large syringe when the boat was back in port

Hi Steve,
I did install a bilge pump in my Typhoon.
It is from Ram Electronic Devices, they are located in the US.

The bilge pump is Ram 45 listed under fail safe devices

Hi, Over the years, I have used numerous setups for bilge pumps and water ingress alarms/switches for members in our club, and ultimately to sell.
I had a friend years ago who was quite adept at devising speciality circuits. He made a water sensor alarm which was only size of a large Postage Stamp. He made approx. 20 units before he died, and I still have one left.
I have another modeli g friend who has found a similar unit on- line which can be wired to a small pump and alarm. I still do have a couple Robbe water pumps in stock. And it is also possible to incorporate a windscreen washer pump into the bilge to suck out the evil water.
