Ballast Pump Setup in 89 SpN

[spiralhelix]

Thought I would share how I added a ballast pump to my 89 SpN with an old Fatboy fat sac I had.

Not sure the coding yet on this forum, so I'll just add a link for the video.

Fill Side:

1 1/4” forstner bit to drill hole (hole saw would have been preferred).

Measured back 10” from garboard drain plug so it would be right at the engine compartment area for installation and use.

Atwood Tsunami 800 GPH aerator or cart pump (important as regular bilge pumps don’t have the inlet fitting) I also went with 800 because the rest of the fittings were easier to get than for the 1200. $24.64 + free shipping https://www.amazon.com/Attwood-Corpo...800&th=1&psc=1

1 1/8” quick twist connect: $8.99 https://www.wakemakers.com/fly-high-...ting-w734.html (for the Tsunami 1200)

Ratcheting Crimper: $22.49 + free shipping https://www.amazon.com/Titan-Tools-1...Z20MJK0EBAJ90Q

*Connections were made in the switch, then the entire inside of the switch was covered in dielectric grease for corrosion resistance.

I added a accessory outlet and plug between the cart pump and battery so the pump didn’t have to be connected all the time. The inline fuse is right at the positive side of the battery to the acc. outlet.


Rough estimate total without tax or shipping, doesn’t include barbed fitting, hose, connectors, crimper: $160.00

SpiralHelix, good on you for making something DIY that seems to fit your needs and also for sharing it.

Looks good. Now go get two more bags for the sides of the engine. Post some wake pictures, too. Been a while since I've seen an original Sport Nautique wake.

[ScooterMcgavin]

Yes post some pics of your wake! I had an original sport nautique. Great job on the ballast.

[spiralhelix]

Thanks! I finished the project just in time to not be able to actually use the system to it's fullest. I have been helping a guy learn to wakeboard all season (extenuating circumstances) and our last session was it for us. But next year I will get some before/after shots. I wanted to get this up before the winter in case others wanted to add it to their winter list of projects. I'll see what I can do about getting more weight, i do have about 6 45# plates, i considered placing under the sac and a couple in the bow until i can get more sacs.

I remember my original sport nautique responded very well to some weight added to the middle ski locker. Great boat with a nicely shaped wake.
