Bilge pump switch/concept for surf

[Mark44]

o

Well let's think about that a second... If your ski is upside down, the ball would float up toward the bottom of the hull. If your ski is upright, the ball falls toward the bottom of the hull.

So either way the air passage would get blocked. Back to the drawing board.

Spring pressure when the ski is upright and when the ski is upside down the water pressure overcomes the spring tension.

Hilarity ensues.

yeah, and then someone actually makes one that works very effectively, and everyone ends up eating their words while begging for seasoning to go with them. good point, matt.

 

[Matt_E]

Let me know whenever that happens, please.

 

[the WaTeRhAwK]

can't we just install one of these in the hood somewhere, connected to an electronic valve that it activates and closes the breather hoses when it detects water? I'm sure it would have to be calibrated so it doesn't activate with small amounts of water though.....

matt, you're the electronic wizard here......

This was hit on before on the four stroke thread,its pretty simple actually,run it off of vacumm using spring loaded flaps.When the engine is running the vacumm overcomes the spring tension and opens the flaps on the air intakes,as soon as the engine stops running the flaps spring closed blocking off water from entering.Cars use vacumm to control all sorts of doors and ducts on the heating and AC systems,simple, reliable and best of all no electronics to get salt water corroded and break.You could also use a vacumm operated switch to work the bilge pump but it would need to be totally sealed or you are back to electronics that break from salt water corrosion again.

here's a couple of things, not sure if one or the other would be useable, but it's talking about flow detection,etc....

I think you mean proximity detection don't you?

Waterhawk, aren't you overthinking this just a tad ?

 

[Matt_E]

Not at all.

He's on to the next big trend in freestyle/freeride 550's.

I once saw a guy wearing a surf leash riding his superjet .That will keep you from getting seperated.All hands on deck (faces or other body parts) That is comedy!

what's the big deal with 550's, matt?

why would wanting to building a high-tech engine hood be "overthinking" ?

You're right.
Go ahead and make a high tech, Pentium powered, electro-mechanical hood with solar panels for a skin.
It will go great with a brainless total loss.

:silly:

this one looks like the one to use.
just install it in the hood and run the breather hose(s) off of it and hook the activation leads to a solenoid valve in the breather tube that will close when it detects a set volume of water passing through it.

* Full scale flow ranges from 0.15 GPH to 400 GPM and .015 SCFH to 2000 SCFM
* Connection sizes from 1/4-inch to 48-inch flange, tube fitting, sanitary, stub-welded, or hot tap
* Construction materials: 316L Stainless Steel (standard), other materials available
* Transmitter outputs include open collector contacts, 5 VDC, or 4-20mA for flow/temperature, or flow/pressure
* Accuracy is 0.5% of rate
* No moving parts or flow obstructions
* Pressure ratings to 10,000 PSIG
* Optional battery powered LCD that displays rate and total
* FACTORY PRE-CALIBRATED TO CUSTOMERS SPECIFICATION

Exactly what is the big deal with 550's .there are other better units with bigger engines out there you know.

yeah, like the 300 lb. square sitting in my garage.
