    My Solution for Auxillary Water Pick Up on Spartan

    Hey guys,

    This is what I finally settled on to try as a second water pick up.

    I will run separate lines for ESC and Motor.

    These trim tab adjusters with water pick up are designed for the SV27, so I had to do a minor mod on the mounting holes.

    The spacing for the holes for the Spartan is 20mm, and the spacing on the pick ups are 18mm. The Spartan also uses a 3mm mounting bolt, which is a bit larger than the bolts used on the SV27 (I'm guessing 2.5mm).

    I offset drilled out the holes with an 11/64" bit (I don't have a 3mm bit) to get the 20mm spacing required. They bolted right on and the bolt heads cover the "slight elongation" of the holes.

    Because the mounting bolts that come with the trim tab adjusters are too small, you will need 4 qty 3mm x 16mm stainless steel bolts to mount the tabs back on the Spartan, if you choose to try this option.





    Kevin

    PS these trim tab adjusters are available from Kintec Racing and I'm sure others as well.

    Will the drag pull the boat to the left? Are they on both sides?

    No, only on one side.

    I have never used this type of pick up before, but I suspect the amount of drag will be negligible. It is adjustable, so you can set it to have the minimum required amount in the water but still provide good water flow.

    Also, the prop is going to walk a bit and make the boat want to turn to the right anyway, so any drag should help counter the effect of prop walk.

    We do think alike... That was the setup I was talking about... Sorry for the oops.... Will go as soon as LHS has another... I wanted you to at least skid it across the ice ... These are a great add on....

    Don't sweat the oops, these things happen, especially when trying something new.

    The brass tubing is 3.95mm OD, so you could use 3mm ID tubing for a snug fit, or 4mm ID tubing and a zip tie to cinch it up tight.

    It's definitely picking up enough flow... If you can, slot the tab and adjuster on either side, so you can use the existing holes...I'd send a pic if I knew how, but it took about 3 minutes on a mill, but a dremel should work. You only have to slot one of the holes on each side, so it lines up with the stock screws.... Amazing how much flow..... Handling, we'll see.... It uses 1/8 id cooling line.....

    After I drilled mine out for the larger bolt size, I just slotted them a bit with a round needle file. They are aluminum, or a similar alloy, and are soft and fairly easy to work.

    Thanks Kevin, did you use the existing screws that came on the boat, or did you drill the hull and use the hardware that came with the tabs? I'm not a big fan of drilling new holes under the waterline.... If the handling on the run today can't be worked out, I'll either try a different location for the tabs, or go back to the stock ones.... It was very windy today, but we'll see tomorrow if the bigger tabs will take out the death wobble.....

    I ran it first time with larger tabs and pickup, it was 15 knot winds, but made a few passes when the wind calmed down, and couldn't get past 3/4 throttle without bad chine walk... Gonna play with tab and pickup settings tomorrow, hopefully less wind in FL, and we shall see... Oh, I forgot, Kevin, do you want to try some different cooling lines? Have perfect size in clear or black... You will have everything Tuesday......

    The bolts that came with the tab adjuster w/water pickup were for the SV27 and were too small in diameter (2.5mm I think)

    I think I could have used the Sartan bolts that came out, but they were a bit short so I used some 3mm x 16mm SS bolts that I had in my kit. Same diameter as stock Spartan bolts, but a bit longer.

    ya i wouldnt recommend using the stock bolts just because u wont have that much bite inside the hull to keep everything in place, i had thought about this to and decided its not enough thread left after the adjusters, and the bolts that come with the adjusters are too small they slide right inside the stock spartan holes lol.... the bigger bolts that came with it are for the adjustments on the tabs not for mounting.. gonna be heading to hardware store today to pick up some better bolts maybe 1/4 inch longer then my stock bolts that should do it... and i dont think big adjustments are key i think small adjustments on the tabs will be key to getting the right settings, ima just leave mine in stock place for the first run and go from there

    Transom pickups are a great way to cool things
    I think deleting the rudder pickup and using two transom pickkups is a great way to go

    Here is phase 2 of my Cooling System Upgrade.

    I installed a rudder modified by forum member Greek75.

    The rudder has an additional pickup bored in, and the inner gallery has been bored to a larger size through the barb and all the way down to the dual pick ups.

    Sorry the photo is a bit blurry, my camera wanted to focus on the strut instead of the rudder.

    BTW, Greek75 did a fantastic job on this modification. Top quality workmanship



    I see the images are missing from my original post. Here they are again.

    Things are still frozen here, probably will be for 3-4 more weeks. We have had a colder than normal spring here and everything is behind.

    So..... Still haven't had a chance to run the boats yet.

    Just bought a Spartan and was wondering where you bought these cool pickups from as I've seen a few people saying the stock setup is not good enough on Lipos.
    Thanks

    These water pickup/trim tab adjusters are available from Kintec racing. They are for the SV27 boat and require a minor modification of filing the mounting holes a bit larger to fit the spartan. Very easy to do.

    You can also get a bolt on dual pickup rudder for the Spartan to provide the extra water inlet.

    Im trying to decide which way to go. Why do you thing the transom inlet is better than the rudder inlet?

    Not necessarily better, but they do work well. When I added mine it was when the Spartan was still pretty new on the scene and the dual pick up rudders were not yet available for the Spartan.

    At least not the ones that are the same dimensions as the stock rudder and bolt on without modification.

    If I were starting from scratch today, I would likely go with a dual pick up rudder just for ease of upgrading.

    Im going to add a pick up to my left adjuster and check flow. Since the adjusters are so easy to fab it would be cheaper and bragging rights if works as well or better than the dual pick up rudder.
