Anyone know for sure if the stock 3/4" ballast intake scupper is pipe threads or standard threads? I want to T off this intake and I bought a pipe thread T, but wanted to find out if the intake was NPT as well before I started disassembling. Thanks.

Yes, I did the drains last season. I changed the drain thru-hulls to 1" ports and all the lines (drain and fill) to 1". To drill out the 3/4" ports to 1", I put a cork in the hole so that the hole saw bit had something to bite on to; worked like a champ. Someone on the forums here suggested that, and it worked great. One note on the drain pumps. I am using the 1100 Rules from wakemakers, but I'm going to switch one of them to the T1200 for comparison. I feel like Rule is not pumping out very fast, and I'm only thinking that because the water doesn't shoot out very far from the boat when draining. Could just be that it's a 1" column of water so thus it doesn't go out as far, but I want to compare it to the T1200.

Dont bother switching. Ive done the flow testing on the Rule 1100 and the Attwood T1200 and the Rule is faster. Heres the just of the testing that I posted on another forum back on Sept. 2011.
Ballast Pump Flow Comparison
--------------------------------------------------------------------------------
I was able to finely get some time this weekend to do some flow comparisons amongst some of the common ballast pumps used.
In this test, I used an Attwood Tsunami T800, T1200 and a Rule 1100 All 3 are common live-well style Aerator pumps used for ballast installs.
I have been wanting to do this anyway, but it moved to the forefront this weekend when it was posted in another thread that the Rule pumps were always over rated, as there is no standard of measuring that is used. Well, doing some investigation, I fond two interesting things: 1) Rule does not list a standard of measurement used to rate their pumps (but that doesnt mean they are over rated). The next bit of info was the most interesting. I found that Rule is under the same parent company as Jabsco, ITT Flow Control, and that in the flow rating for the Jabsco, there to is no std of measurement listed. So, is it safe to say that the Jabsco Ballast Puppy too is over rated?????? Well, we will have to answer that question later, as I did not break out the only Puppy I have on hand and test it, but i will here at some point.
Here is how I laid the test out. I tried to make at as real-world as possible, so I set up a mock ballast setup.
I used a Fly High W713 v-drive sac rated @ 400 lbs
5 gal bucket fed by hose as water supply
deep-cycle battery with 2A trickle charge
5' fill hose from pump to top of sac
2' hose from vent on top of sac.
The water supply was lower then sac, typical of a ballast install, and the vent was higher then sac. Sac was drain dry between each test. The clock started as soon as the pump was turned on, and the clock was stopped as soon as I had a steady flow from the vent. Each pump was run 3 times to get an average. For the Rule and T1200, I used 1" hose and 1" fly High quick-connect fittings. For the T800, I used both 1" and 3/4" hose slid over the threads, as well as 3/4 hose on the supplied 3/4" barbed fitting. For on of the T1200 tests, I also used the Fly High W747 3/4" sac valve threads x 1-1/8" Tsunami threads adapter.
Rule 405FC 1100 GPH pump. 3/4" threaded inlet and a 1-1/8" outlet and 1" hose: 4:29 avg fill time.
Attwood Tsunami T1200 pump. 1-1/8 inlet and 1-1/8 outlet and 1" hose: 4:37 avg fill time.
Attwood Tsunami T1200 pump. 1-1/8 inlet and 1-1/8 outlet and 1" hose and W747 adapter: 4:44 avg fill time.
Attwood Tsunami T800 pump. 3/4" inlet and outlet with 1" hose. 4:57 avg fill time.
Attwood Tsunami T800 pump. 3/4" inlet and outlet with 3/4' hose and 3/4 Fly High quick-connects. 5:11 avg fill time
Attwood Tsunami T800 pump. 3/4" inlet and outlet with 3/4' hose and 3/4 Fly High quick-connects and the supplied 3/4 hose-barb connection on the outlet of the pump. 5:25 avg fill time.
Two surprises, here! 1, the Rule 1100 was actually faster then the Tsunami T1200. Not by alot, but IMO, certainly not well over rated 2, the W747 adapter did not slow the T1200 flow down as much as I expected. This is great news, because with the use of the adapter, you can easily mate this pump right to a 3/4" thru-hull setup, and not loose a ton of volume.
Again, this was not meant to be scientific, but simply to compare these pumps flow rates in what is as close to a real world situation as possible. So, take the info with a grain of salt.Last edited by MLA; 07-03-2012 at 09:11 PM.

Looks like MLA has it down. I noticed that with my old 3/4" lines out the back for draining it was more of a pressure spray shooting out a few feet, even with just the little Rule 700 powering it.
With the T-1200 on a one inch drain line it's more like a, uh, ever seen a cow taking a piss?
So when is this "old enough to know better" supposed to kick in?
