    well this annoys me but I just finished making a new bait tank for the Bertram and I just got it lifted in a trailer last friday. I am leaving for Westport Friday morning where she shall stay the rest of the summer.

    Much to my dismay I found the thru hull for the washdown, which is the thru hull I was planning to tap into, is just a thru hull with no scoop. I have never tried running a bait tank off a thru hull with no scooop and obviously it’s preferred. But at this point there isn’t enough time to get it done right without cancelling a fishing trip.

    The thru hull is mounted behind the transmissions in a twin diesel boat that cruises at 25kts but never really gets very far out of the water. Is it worth trying or is it proven that it will not work? My other option is to mount an external transom mounted unit.

    The tank is about 40g.

    Many of these boats don’t have a scoop... actually if the do have a scoop it points towards the rear of the boat and doesn’t really help direct water into the through hull..... I think you’ll be fine.....

    The bait tank on my Defiance did not have a scoop, the bait tank on my Rampage no scoop, the bait tank on the new Hatteras has no scoop....

    If it stays in the water it should suck water just fine and keep your bait alive....

    We don't have a scoop on the washdown pump or the bait tank pump. They still work at speed.

    You need the scoop no matter what. Good luck should be a great set up.

    Very different boat but I tried to T into my washdown pump intake, which doesn't have a scoop and is always in the water. Without the scoop I did not have sufficient flow and dead bait.

    If your boat isn't going to come out of the water much you'll be fine. Most pumps will clear air on their own if installed correctly. Even with no scoop, mine will continue to push water when on plane, even after I turn the pump off.

    Mine doesn't suck enough water on step to keep bait alive so I took my intake screen off and fitted a 90degree pvc pipe onto it. Fitted the intake screen onto the 90. Now I can rotate it, up when Im not tuna fishing and don't need constant flow and down, even with the hull when tuna fishing. Works good.

    I will put it this way, without the scoop you are not getting all you can get, if the pick-up is located far enough back you may get away with it, however I would correct that ASAP.

    I’d rather miss a trip and get it fixed than to half ass it. Just me. It will cavitate and suck air.

    Screenshot_20190724-142009_Chrome.jpg You can find the "BRASS" scoop/grate that screw on that go over the intake fitting, try fisheries supply or seattle marine.

    I do not have the scoop on mine but have a high speed pickup that goes into a groco sea strainer and appears to work fine (have not tried it with bait yet but fills and stays filled with what appears to be good flow at speed). It has a cutout on the leading edge to channel water based on pressure differential I think. Different than just the plain thru hulls. So if you have that may still be OK or sounds like adding the scoop per Paul's advice is a relatively easy way to go.

    I don’t have a scoop and I am on step all the times I run, no issues but then my pump is a sureflow, not one of those cheesey bait well pumps. Mine never cavitates that I know of but it is pretty far back.

    Yep! That's the way I plumbed my NR O/S and there was never an issue. Always plenty of water to the tank. I did use a high volume Sureflow pump.

    the water moving fast past the opening can create suction and overwhelm the pump depending on speed and bottom config...you'll soon find out

    Never would have thought you’d make such a rookie move.
