RE: 750 install

I did not reinforce mine yet, but I need to as they bow inward when the bags are full. That is a winter project this year. I am thinking about using some more modern materials like what they are using now. The black panels on the new boats look good with no carpet on them, but I am just curious as to how it affects the engine noise. I would think that the carpet helps knock some noise down. Once I get started on it I will post a thread.

RE: 750 install

I plan on jerking the hard tanks out of my 230 this winter and replacing them with 750's too. I'll take some pics.

RE: 750 install

Great day! Went out with wakeboard1 and we tried out my 750 sac install. Worked great.. Both of us got in a good set under some great weather. Couldn't ask for a better day.

Alright, for those of you always looking to save a buck like me, here is how I did this by using the aerator pumps instead of buying high dollar ballast puppies:

Gut the hard tanks, but leave your hoses in place.
From the fill hose connect a "T" fitting so that the water has to go right or left when it comes out of the hose.
Connect a short hose to one side of the T- connect that hose to the bottom fitting of your sac. This will now fill the sac.
Connect a short hose to the other side of the T -connect this hose to your empty pump - connect your factory hose to the empty pump so now the water can pump out the side of the boat.
All thats left is to connect your overflow hose to the top of the sac. You need to put a shut-off valve in that hose.

What I did with the empty pump.
When you take out your tanks you will see a small area where the empty pumps are when attached to the hard tanks. Kinda like a box with no top on it. I Mounted my pumps in there. I didn't want the sacs to put any pressure on them so I cut a piece of treated 2X12 to cover the pumps. Painted them black for now, may get matching carpet later. Leave 6" or so for all of the hoses to come up from the pump.

For this to work, you kinda have to run it like the piggy back method. Open your valves on the overflow, and plug the empty holes on the side of the boat. fill the sacs, close your valves on the overflow. Smile while you stand in ankle deap water on your swim step. Ride till you can't anymore. Then take out your plugs, drain water and go get a massage from the lady friend.

Pretty easy. If anyone needs pics let me know.

I did something similar, but just took the carpeted pieces that covered the stock tanks and cut 6 inches off the long side.

I thought about that. Then I thought if I ever sold the boat, I want to be able to set everthing back to stock depending on the desires of the buyer.

Had a few request for pics so here you go.

Nice install, thanks for sharing the pics!

For anyone that is looking for some new ballast puppy pumps (or any ballast products for that matter), we do have a discount available for Planet Nautique members, so shoot me an email for more info.

Sorry to revive an ancient thread, but didn't want to start another ballast thread. I have an '03 SAN. I replaced the rear tanks with fly high bags over the weekend. I did a straight swap. Drain pump at the rear bottom fitting of the bag, fill line to one of the top fittings, and vent line to the other top fitting. After reading jward's posts it appears I may be missing something. Am I going to have issues when I try out the new setup tomorrow? The only problem I can think of would be the additional volume of water pushing through the drain pump and out of the boat. If this happens I'll just install an inline valve. Any other problems I need to be aware of?

Thanks.

If you stuck with the same pumps (which it appears you did), you are going to have some long fill and drain times, as I believe both of those pumps are off a 3/4" thru-hull. Other than that, I think the 2003 setup should work. I think you are going to have to close the ball valve though to keep them from draining when at rest. I'm not super familiar with the 2003 setup (which is different from the 99 and 2000 setups that I am familiar with), but I think that the 2003 stock system still uses the combination of a closed vent line coupled with a hard tank to prevent water from flowing past the propeller in the aerator pump on the drain line. This does not work with soft bags, because they just compress. The hard tanks can't compress, so they hold the water in because they have no air to replace it with. It's a vaccuum / pressure thing.

But I could be wrong about how yours works. There may be a relay with a gate valve on those lines, so you might be okay. You should find out pretty quickly though, and if they are draining when you don't want them to be, just close the ball valve.

[MBKY210]

Thanks for the info. I guess I'll find out if it works today. I'll post how or if it works in case anybody is thinking of trying this.

Please Do, I have my 750's sitting here in boxes ready to go with the exact same plan(straight swap for hard tanks).

In the same boat, looking to make a straight swap as soon as my bags get in.

^ Chexi is dead on with this one. I had the exact same problem last year when I tried to attach the stock Rule 1100 GPH aerator to the empty port in the 750. It would just push the water out and we'd have a half-empty bag after a couple minutes. You'll either have to put a manual valve in the empty line or go with the puppies.

[MBKY210]

Tried out my setup last night and I would say it was successful. Just to clarify... '03 SAN, I replaced my hard tanks with 400# sacs... straight swap so the fill/drain system is stock... just have bags instead of tanks. Sacs filled easily and quickly (~6-7 minutes). If I lost any water out of them while riding it was minimal. This may be different for 750s. The extra water in the 750 may push through the drain line. This could easily be fixed with a manual valve. The sacs drained easily and quickly also. There may have been a gallon of water or less left in the sac after draining. No biggie in my opinion.

Maybe one day when I have the cash and the time I'll go the ballast puppy route, but for the time being this will work...ballin' on a budget for sure.
