Super Jet Help me wrap my head around this

[Quinc]

Putting my pump back together and I want to setup dual cooling and ditch the stock bilge. ( Going to run two electric bilges) So my question is if I can fill in the bilge with epoxy and tap it with a brass fitting for another cooling line. So this is the part I am having trouble with. If I run a line from the bilge portion of the pump, wouldn't it still work as a bilge? What is the difference between the hole in the pump housing for the bilge vs cooling line?

Bilge side:

Cooling side:

Bilge comes off the reduction nozzle not the stator.

That 2nd hole you have is for cooling assuming its not too big to tap. may have to go to a 1/4 npt fitting there.

It is a 1991 SN, I don't think the bilges came off the nozzles until 93?

Did some searching and believe this is the New vs old:

water blowing out that big old hole, then goes thru a Y fitting. as the water rushes past the Y it creates a vacuum in the small tube, that sucks the water out of the bilge. just like a bead/sand blaster nozzle. if you want to leave that as a bilge, just drill another hole, put a fitting and run dual cooling.

I tried this before- Bad Idea, I had to run my bilges constantly. I was surprized at how much water the stock bilge removes. Its much better to install an extra line if your set on dual cooling, its actually pretty easy, Like a 10 minute job.

This x10. Keep the stock bilge. Bilges fail. Trust me. I've had a few. From rule to tsunami. They all will. Honestly the rules are the worst from my experience.

I still haven't put in the footholds so I might keep it. I have a Blowsion hood and new hood seal so shouldn't get too much water in the hull. Hopefully...

Never know! Something catastrophic could happen and you get a huge flow of water and your bilges won't work..Switch could fail, or you could have something get stuck in your pump and it'd blow a fuse.. That's happened to me before.
I'd recommend getting a ratchet hood strap if you haven't already too.
If you've already got the tray apart yeah, just put in a new line.

idk, personally i have had NO issues running dual bilges. and i will be running dual cooling next year. I ride inland lakes though, no surf. Only time i really need to run the bilge pumps is when i am power stabbin or subbin my ski. and with dual bilges, you turn em on and you are good to go... i am running a 800gph and a 500gph right now. when my 500 craps out i will be putting in another 800, just because i like doin subs.

if a fuse blows cause he has something stuck in his pump, the stock bilge still wouldnt work... right? so in that situation, anyone would be $cr3wed. But i do agree, if tray is already out, and you have the option, run a new seperate line for the dual cooling and keep stock bilge for the H3ll of it.

To answer the question you originally posted.... I always put tape on the inside of that big hole, pack it full of jb weld, remove the tape after it has hardened completely, then drilled and tapped for my second cooling line. I have been doing this for years and never had one issue.

I meant if he has something stuck in his bilge pumps motor. Like a small stick, screw, anything. I've had that happen and it blows a fuse , but the stock siphon was still working so I could still ride. Now with a new hood seal, sn hood mod, ratchet strap, I'm not too worried about water ingestion, but with a stock siphon I won't always need to run my bilges except when I'm underwater alot.

Make sure to take dremel and grind some lines and relief areas inside metal area to be epoxied first. This will give you a mechanical lock as well as chemical bond. Have seen several blown motors from epoxy pulling out and loss of cooling...

Yep, forgot to add that I do scuff the inside and make it rough as possible. Thanks for the extra input!
