superjet bilge siphon removal?

[superjet44]

i have been riding my 2010 superjet for a while and i notice it takes on a little water and the original bilge siphon doesnt pump it out very good, i am planning on getting a bilge pump for it but i want to know how to get rid of the original siphon.
thank you

I would recommend keeping it. It is basically foolproof unless a human messes with it. As long as there is water exiting the jetpump, it will suck out water.

Ditto. I agree with Bruce. I run a stock siphon an a bilge pump

I run a scupper, stock siphon and a rule 500 bilge in both my boats. You can never have enough water removal methods. The siphon is the most reliable though, the other two have a better chance of failing.

thanks for the help

I run two 500gph rule bilges and the stock siphon. Doesn't hurt to leave it in there, it doesn't weight anything, so you won't be cutting weight by removing it.

the siphon tube works well for dual cooling!

Seams to me that if you use this as a cooling line, the water is going out not in.

it would if u hooked to it, but most ppl drill and tap and put a fitting.

A new fitting on the pump is typically tapped and then the line runs through the siphon tube. The whole point in using the siphon tube is that you don't have to drill and install a new tube through the foam and bulkhead. IMO... If you aren't going to use that tube for dual cooling, leave the siphon in place.

Would the stock siphon on the reduction nozzle still work if it was bored out? Is there enough pull/pressure on a flush surface instead of siphon sticking out in flow. Would boring the stock siphon flush and leaving it operational be a problem with water intrusion?

I think I read somewhere you can use that siphon tube to run a trim cable through also.

Can anyone answer these questions any knowledge would be greatly appreciated

Bored out...not sure. I tend to trust Yamaha engineering though.

Cut flush, the answer is a big no. The tube must extend into a negative pressure area of the jet stream. If you shorten it or cut it flush, then it will then be in a positive pressure area of the jet stream and it will in fact pump water into your hull. Ask me how I know this.

What he said^^^

You can bore without cutting the tube if you use a dremel style of boring.

Don't remove the tube. You will be pumping water into your bilge instead of removing it.

 

[BruceSki]

Other option is to remove the tube....bore it out....then re-install a tube about the same size. Stainless or aluminum is best.

Great info thanks guys

 

[superjetguy]

On the other end of it. I've always had that tube as a dual cooling line instead and used a rule 500 as my only way to remove water. It worked fine. If your bilge stops working you can tell when your ski is heavy.

Superjetguy what type of riding do you do?

 

[superjetguy]

Everything. Lakes, delta, and ocean
