Bilge pump mounting

2ndchance · #1 03-15-2007, 11:34 PM

Looking for some advice/opinions. I am going to put a new bilge pump in the 2ndchance (750 GPH with a float switch) and I would like to here how some you guys did yours. My plan is to put a dab of 5200 under the pump and let hold it. Other options will be considered.

Sounds like a plan, but I'd use a bigger pump such as a Rule 1500. In my 87' there is a pad glassed in that the pump is mounted to.

i like two 1500 gph pumps minimum, remember, the bilge pumps are rated at 14 volts with no head pressure. Drop the voltage down to 12 volts, add 6 ft of corrigated hose with about 3 ft of head, and you'll be lucky if that 750 pumps 250. Your drain plug hole will let well over 250 in if you happen to leave the plug out.

I have a flat plate right in front of my drain plug that I mounted mine to. I would use screws to mount both *because you do not want to take a chance of them comming loose. I would wire directly to the battery and to a switch on you dash. If you leave the boat in the water you may want to add a second float as a back up. My boat sank years back because the float switch failed in a day of very heavy rain and I was out of town. I also agree with others and go with a min. of 1500.

Most pumps come with its own bracket, try to use the biggest pump you can afford!!

Mount pump up off the floor of the bilge about 2 inches. This will keep all the heavy sand and stuff on the bottom.

If you don't you will suck up every thing from sand to what ever is in there and be burning up pumps faster then you can buy them!!

If you are leaving the boat in the water then you will need a float switch or a pump with a built in float & a 2nd battery.
