Converting my Prowler hatch for live bait tank

I’m going to show some pictures of my Prowler 4.3’s live bait tank which I’ve made. It works very well and keeps fish alive for many hours. You do get some water overflowing at times but hey it is a water sport. I find its position is great as you can easily access the fish and keep a eye on them to see how they are doing. All parts are available from the BLA site

PLEASE NOTE: If you don’t install this property you may get water going into the hull of your kayak causing you some safety concerns. I haven’ had a drop go into my hull and I made sure I used plenty of fix seal MSP clear which is a strong adhesive sealant around my holes.


Here’s what you need:

  • 2 x white through hull skin fittings
  • 310ml Aquaseal Marine Sealant – mSEAL 595 clear (BLA sku: 264156)
  • 1 x Whale High Flow Submersible Pump (BLA sku: 133104)
  • Irrigation fittings
  • 1 x rubber boot switch
  • 1 x strap

Here’s how I did it:

step 1



You need two of these through hull skin fittings.

Then drill two holes so the thread just fits snug through the hole.

I placed my kayak in the water and filled the tank up with water to see where to position height of the holes.

Make sure you put plenty of fix seal between the fitting and your kayak to ensure you don’t get any water leaks into your kayak!

You need a Whale pump next which simply fits into the scupper hole.



I then just used some irrigation fittings to get the water from the pump to the tank.

I’ve also put a couple of fittings on the inside so the water flows up the tank.


The wire from the pump then goes in through the hole at the front of the hatch. make sure you leave it loose enough so you can still lift your hatch and turn it around.


You then wire it up to a switch. This is the switch, you can see i’ve used a switch with a rubber boot over the top to stop water getting in. I also embedded the hole underside of the switch with silicon as well as the hole the wire comes out of and in the hole where the fish finder wire goes into the small hatch. This is to ensure you don’t get any salt water into you switch and wires. I’ve had mine for over a year now and it still works no problems.


The wire from the switch then goes back out the same hole and straight across into the hull of the kayak where it connects to the battery.


I just have my battery sitting on the bottom of my hull and use a strap to strap it back to a bit of the kayak moulding. This ensures it stays in position in rough seas and doesn’t get disconnected.

Now your ready to load it up with water and put your livies into it. Pending on what livies you have in there and how many as to how long you need to run the pump. I usually turn mine on and off as needed.
