Electric pump installation with unique features^

Post by JulesT » Sun Apr 22, 2007 9:38 pm

I spent some time in the winter fitting an electric pump. This has a unique solution to some of the common problems encountered with electric pump installations. I've now tried it out and first indications are very good - it works well! The write up is at the following link. http://www.zen40268.zen.co.uk/seakayaki ... ation.html. lI'd be interested to hear any comments from readers.

I hate to drill a hole in my new North Shore Mariner.

Very clever Jules, my hat's off to you mate!
How easy would it be to shape the outlet to "hook" the cockpit rim?

Great ! Think I'll head into town tomorrow for the bits before you patent it :-)

Looks good. How much did it all cost?

Instead of the slightly skanky cockpit coaming contact plate
you could use a 2 or 3 mm wire bar. It could be threaded through two holes about 6 or 8 inches apart. This design would depend on the profile of the coaming and is perhaps more suitable for a plastic boat.

Interesting idea!

Is there a risk of a partial circuit being made when the inside of the boat is wet with salt water? I probably wouldn't be enough to run the pump but could it flatten your battery?

Cheers,

Tom.

Thanks for the feedback guys for some reason I wasnt getting topic reply notifications so per chance I notcied just now.

Tom - unlikely; OK the pipe end could be in salt water but the cockpit coaming contact isnt - time and testing will tell

Guy - the current setup allows a range of positions of the tube against the contact. A single wire may be a bit more of a hit and miss contact. But yes I might try to remake the contact so it looks a bit better. You wont see it with the spraydeck on.

Cost? pump approx 18, battery 13 (+charger if you havent got one). Fuse holder and wire a few quid. Poly pipe a few quid. The rest left over bits from hoarding. Its not so much the cost as the availability / replaceability / alterability and whether you can make it work in your specific kayak.

Pelagic - a slight curve in the tube would help. Need to try a pipe bender. Copper tube would bend easily but probably go green in salt water and sizing is a problem; 15 or 22 mm standard. My SS bit of tube is either 19 or 20mm and fits in polypipe perfectly.

I just came across this and I am suitably impressed! I'd be interested to hear the latest from your R&D dept!
