I would try contacting Robbe, as they say they have the instructions Online, but the page doesn't seem readily accessable. http://at.robbe-online.net/rims_at.storefront/en

[edit] Perhaps you just have to Register on the Robbe Site to access the instruction library.

The pump(s) in my fire boat are custom pumps. I cast them up, and a friend helped with the seals.
We guesstimate that it pumps about 3 gallons a minute.[>:] And I have designed for three pumps.[>:] http://www.rcgroups.com/forums/attac...hmentid=151803
I have seen pretty good results from a boat in Seattle that uses a smaller RV water pump designed for sink and shower facilities. The trick is finding the small one.

When you are ready to launch let me know, If I have time I will sail support.[8D]
