View Full Version : Ballast pump details

I have the Rule 700GPH Aerator Pump out of my boat and I have been over it with a magnifying glass and can't find a part number. I have been on the Rule Industries website and can't find an exact match. I found some that are close, but nothing exact, and with the tight space and special mounting bracket I am afraid to get something that is a little different.

Can someone at SC give me some guidance?

Does your look like the solid style? What I mean is the "old" style the motor and pump housing are one piece. The newer ones are two piece. The motor seperates from the housing. I like the new model better. You do not have to uninstall the entire unit. You just unsnap the motor from the pump housing and change the motor cartridge. It should be the same size as your old one, just two pieces.

I think these are the part numbers, I will verify this weekend:

201FC Pro Series 500 LW Pump, Seacock Fitting
203FC Pro Series 700 LW Pump, Seacock Fitting

Yea, that is what I was thinking, but I was not sure if the "seacock" fitting was threaded or not.

Ok, here is the info from the Rule site. It is described as having 1" tapered threads. Just click on the model numbers for the different flow rates.

Yours should be the 203FC

Is yours the arrtridge style like my pic above and do you only need the motor. I ask this because sometimes, the housing is broken and you need both parts. The link below is for the motor only.

If so you can order one from here --> http://www.boatersworld.com/product/477200125.htm

It seems that the 203FC has been discontinued from Rule. the only replacement seems to be the 500gph, but i really don't want to downgrade. has anyone found a suitable replacement?

btw.. i have the old style that is glued together and a 07 LSV. back left empty pump has a dead short in it.

I ended up finding a 800gph Tsunami areator pump at walmart for $25. It works great... Although it is a little bit louder than the original.
