|Has anyone tried using the scupper or scoop type of thru hull water inlets to fill a sac WITHOUT USING A PUMP? |
|Still working on you set up?? |
I do remember an old post about someone making some type of scupper that would create enough force to fill and could be reversed and used to drain… I don’t think it was like a normal brass thru-hull scupper though.
Someone also made a pvc type scupper under the hull but I think they still used a pump. (not sure)
|Still working. I have it all figured out but not sure if I can get the hoses over the gas tank.|
|I used a small scupper to prime my pump, and as it turnes out it will fill a sac too. I found this out after I drained the sacs and forgot to turn off the shutoff valve on the pump. While driving back to the dock, the scupper was scooping up water and filling the sacs without the pump. So yes, you can. Also, the scupper I made is small. I used a 1 inch pvc elbow fitting and cut it in half lenghwise and glued it to the bottom of the boat and the tru hull fitting with J.B Weld. It works like nobodys business|
|Does it fill it pretty tight?|
|have any pics of that set up?|
|There is a manifold system used in combination with a "scoop" type under hull pickup manufactured by Launch Pad. It was advertised in Level X recently, but I can't tell you which issue because I loaned it to a friend. I think it was towards the front in a "new products" feature. |
I think Launch Pad is a Straight Line company. I think this might be worth tracking down...
|Claibra has a scoop on there boats for there ballest sytems.It fills in 45 sec and draines in 15 sec.|
|Dont they use the scoop intake for the water intake to cool the engine? Also, the calabria uses like 2 3inch inlets at the back of the boat, so it has to be stoped to fill, but has to be moving or on the trailer to empty|
|Hey bt lowe, |
I looked all over on the straightline site and could find anything.
Yes, you cna fill sacs with just the scoop. It is not all that effective though, and you will still need to put some type of shut off valve on it or you will blow up your bags.
|Yeah, I did the same. The manifold was in Level X magazine as a little product-promo type spot. It allowed up to 5 pumps to run off a single "scoop" style intake. |
The article had a phone number of the inventor/mfg., and I'm pretty sure it was the same inventor of the "launch pad", which is a straight line product.
I'll see if I can track down the number...
|If you could. That would be very cool. I dropped an email to straightline also. |
|I had a flush type through hull fitting with a rule 4000 GPH, had endless troubles getting the pump primed etc, I made a scoop out of a piece of pipe and pushed it into the through hull fitting and it halved the fill time on the system. Now I can fill 3 sacs for a total of 1500 pounds in about 5 mins.|
|Did you glue it in?|
