    Fresh water pump

    I'm afraid I might have to replace our fresh water pump next weekend. I say "might" because I didn't have my volt meter with me to confirm power is present at the pump. The fuses look good and the light comes on at the switch. The pump does nothing - not a sound and no heat. If I end up having to replace it, does anyone have any tips and/or warnings? It looks pretty straightforward to me, but I am new to this. It is a Shurflo 5.7 GPM.

    Going by memory only, it was pretty straight forward. I'm a real Capt Rooster Poot when it comes to electricity so I remove fuse first - disconnect the battery cables - Disconnect old red and black wires from pump - remove hose - remove pump - install new pump - reconnect hose - reconnect wires (check for proper polarity) - reconnect battery cables - put fuse back in - pucker your cheeks and turm on the faucet. If that dont fix it send a private message to Old Houseboater .

    They are easy to replace - especially if you go with the same model. If you switch to something different, you may have to do a little plumbing. Hopefully it is plumbed with cutoffs on both sides of the pump so that you do not get much water in the hull.

    I got off easy on this one! The switch was defective. It was dropping most of the voltage across the switch. Pump now works great!

    Good deal, a $15 dollar switch verses a $300 pump. Radio Shack is always my friend for switches in a pinch

    You are absolutely right! I was not wanting to drop 300 bucks. I'm trying to find a switch to match the others on the console. It's one of those rectangular rocker switches with a light. Can anybody recommend some good places for boat & electrical parts online?

    Most of the switches you see are either Pollak http://products.pollakaftermarket.co...ocker-switches or Cole Hersee http://www.colehersee.com/home/grid/cat/2/. If you weren't tied to matching what was there, or if you were lucky enough that your manufacturer used really good switches, it is hard to beat Blue Sea Systems stuff. http://bluesea.com/category/8/33/pro...e/overview/147.

    None of these manufacturers sell retail, but a Google products search will bring up an online seller for a specific model number.
