    I know I can get one there but I am kind of strapped for cash so if I can make one for a little bit less cost that's what I'll do I just don't want to spend anymore Money then I have to

    One way is to get a small electric toy boat that uses an impeller for propulsion and take it apart for the parts. I bought one at KB toys for 5 bucks, and haven't taken it apart yet.

    There used to be a really good article on how to make an impeller with copper plates by soldering them to a base plate. Use pvc caps and suchlike for the housing.

    Scrounging for fun and profit:

    I made a really little proof of concept once with a small motor from a printer. Darn thing didn't work after I mailed it off. About the diameter of a quarter. Printers can be found for 5 bucks at thrift shops at times, and will supply you with all kinds of things :) Lots of screws, Lots of gears, Lots of wire. The older, the better. Old non working VCR's can be canibalized also. The head has some high quality bearings, If you can get them out without destroying them. I'll bet you can find dead printers and vcrs for the asking, and there is a lot of fun in taking them apart :) And the base cabinets are sometimes aluminum, which can get you some cash at a recycling center. All the too thin copper could also be saved up.

    I've used windshield washer motors with poor sucess, as these sometimes are only for intermittent pumping. And work great, until the mechanism fries itself.

    Luck

    Sometimes you can find suitable models available for other purposes. I know Michael's stores had a fountain pump on sale a few years ago that was small, ran on 6V, & pumped enough for a small ship.

    If I make my pump which motor from battler's connection do you think would be good enough for use as a pump motor?

    You have several options; presumably you want the smallest that will yield the desired flowrate, which is dependent upon the geometry of the impeller and pump housing so it's possible that you may need to do a bit of experimenting before finding an optimal choice. An alternate source of electric motors besides Battlers Connection would be Visit this site

    There's always Radio Shack. If I remember correctly you are shooting for somewhere in the neighborhood of 30 gpm... I'll bet that the radio shack motor 3-6v or so will do that.

    This hobby is not that spendy. Compair it to airplanes, helicopters. Even fishing & hunting cost way more. You'd drop 10x the cash on an ultimate fishing trip compaired to going to NATS. ATV, dirt bike, fishing boat, restoring cars, flying real planes, stopping at the bar, eating out, sports games, gambleing. All "Hobby" stuff that cost way more then the ships. For $1000 you can build a ship. $200-$300 per year maintains it. $1000 a year to go to NATS & 2 regional battles.
    Cheap.

    Tis true. I have $$$ wrapped up in model airplanes. Although the average sport plane only costs around $350 ready to fly, the bigger more complicated aircraft can run thousands of $$.

    Same goes for RC cars. When I raced 1/8 scale off road competatively, my car ran $1500. Add in the cost of fuel for each racing weekend, plus a couple sets of new tires for each major race, and the cost skyrocketed!

    Our warships might cost a good amount of money to get into the hobby, but once in the cost to maintain seems to be lower (especially if you resist the urge to build yet another ship!) heh.
