Dual Bilges

[BruceSki]

i bought two attwood 500's today and i was mocking them up to see where im going to set them up

one fits to the grease fitting side of the thru hull perfectly, but the other wont fit on the other side due to the stock bilge.\

just wondering where everyone is mounting the second one if they are running attwoods...

i want to keep the stock bilge along with the two electric ones.

i am running a third line thru hull for my dual cooling line for when i add a pipe later on..

Slide the stock bilge siphon forward under the motor and mount the attwoods on either side of the mid-shaft.

so i should ditch the bracket that holds the siphon and just 5200 the siphon to the bottom?

didnt even think of this

That's what I did except for the "5200 the siphon" part.
I had the water outlets from the attwoods face forward (towards the front of the ski) and stuck the siphon under the hoses. Never moved once without any glue.

man your batting 1000....

thats an even better idea...

gonna mock it up like that tonight and see how it fits...

thanks for the good idea, i was stumped on how to do it...didnt think of moving the stocker...

(guess i need to get my head outside the box a little)


thanks boris

Maybe now is the time to go dual cooling, you'll get the stock bilge syphon out of the way and be all set to go if you were going to do it down the road anyhow...

i want to keep it there as a third form of protection...plus it gets the hull super dry, more than the bilges will.....and no scuppers for me...

im putting in another stainless thru hull line for the dual cooling so i can keep the bigle

I kept the stock syphon, put one bilge in the back under the drive shaft, and the other up front in between the gas tank and engine.

I actually see more water come out of my front bilge than the rear.

interesting

Definately keep the stock siphon if you don't have scuppers. Otherwise you have NO way of getting water out if the pumps fail.

You can't 5200 the stock one as I"m pretty sure all the openings are on the bottom (the the 5200 would close them all up).

I also put my stock siphon under the bilge pump hoses and used zip ties to hold it in place (before I got my scuppers and dual cooling that is)

Since I have the 1.5 inch Home Depot one way's in all my boats, the pumps very rarely even pump water out, just never have a problem.

Thats surprising, I always thought those were placed poorly when I saw people running them. I guess if you are really ingesting a lot of water they would work but I just always thought the rear bilge would pump more due to the angle when riding on kneeling in the tray.

I guess if the ski was weightless it would work, but usually after I sink my ski I get it back up on plane as fast as I can. Seems to have worked so far for me.

I just zip tied it to one of the pump hoses. I ran the pump hoses facing out. The shorter the pump hose the more efficiently the pumps work. My hoses are only 1 foot and the siphon hose is behind the pumps against the wall with a small pickup screen from a polaris on it.

If freestyle, I would put one up front and just put in a scupper.

#0 on the boards actually turned a rule 500 into a stock syphoning bilge when the pump wasn't turned on by hooking it up the same way the stock bilge was hooked up. It works really well for him.

im scared of scuppers....i just started riding the surf now that i have a newer boat i trust out there... but i dotn want to flip it and be far away and watch it go under:Thinkingof_:

thats pretty wild....so it still works as an electric bilge as well???



just an fyi i wound up mounting one right under the couplers along with the stocker in the stock location....i put the other on the pipe side of the boat since i usually lean it that way after i take on water to keep it away from the carbs...just a habit i guess but i figured it would help out the other pump if i take on a ton of water


i attached a crappy pic of when i 5200 the bases on the other day....i have since clipped the bilges in, ran the hoses and drilled and fitted the two bilge fittings.... i need to get the camera back over to the garage and take some newer pics


thanks for all the help guys
