SAN 210 trim tabs!

[Nordicron]

Most intense scariest mod I've done to date but so so so worth every penny and every hole I drilled into her!!!

No idea if they work as surf tabs yet, I imagine they wouldn't, they will have an effect I'm sure but won't work like the MC gen 2 but will try it and report.

But OMG they help the boat plane so so well and is why I did it. I run a 1235 prop already and that does ok but there is a fine line with how much rear weight I can run and get on plane. Today I filled all my rear weight(stock plus 750 bags) front tank and arrow. Had 50lbs lead in nose and a 50lb lead bag on the front tank under the hatch(perfect spot for 1 bag). Normally to get on plane in a decent amount of time I have to also move about 200lb more lead to the front and boat still very slow to plane. Today I left 400 lbs in rear and boat planned in about the same time as it did with full stock maybe a tad slower. Almost zero bow rise. Tried to get up like this without deploying tabs and it wouldn't get over 12mph! And the wake was rocking!!!! I'm sure I can run even more and plane out now no problem.

Next mod is to figure out how to turn this into a autolaunch system! I have some ideas but it involves way to many relays! The hardest part about doing this other than getting the guts to drill into the hull was figuring out how to deal with the rounded transom on our boats and the flat surface required to mount the tabs. I overcame this issue using some composite shims. I used the belt sander to take them down to basically zero at the start of the shim.

I'd highly recommend this to anyone wanting to run heavy. Running more tail weight adds a very nice lip! Loving my Nauti wake again!

nice work! how did you power the tabs?

[Paxdad]

Let us know how the overall ride of the boat is effected. Clean looking install!

I have basically the same ballast setup (I have the integrated bow sack, not the arrow sack) and run the 1617 prop and I have zero complains with how fast it planes. I'm really surprised the 1235 isn't enough. Neat mod, but it seems like a better prop would have solved your problem for a lot less money - unless you need 40+ mph top-end.

[Paxdad]

It will be interesting to see/ hear if you can run less weight with one tab down and the other up. Or with both tabs down if you can lengthen the surf pocket and wave length as it will push the bow down. I would think that there is a real benefit when it comes to fine tuning the surf wake.

Okwake- if your getting on plane in under 30secs with FULL 750's and only a int bow sac, assuming full stock and no other nose weight I'm very surprised.

This is my boat...

750s on top of the hard tanks in the back as full as they will go. Integrated bow sack in the front. Full stock ballast. 250 lbs of pop bags on port side to offset prop rotation.

Jeff has it at 9.3 seconds. I've never timed it, but it sounds about right to me.

I got the ACME 1433 4 Blade 14" x 14.25" Propeller last year and love it. We usually run 2 button presses in the back (no hard tanks, 1,100 bags) and full belly and we get on plane in about 10 seconds. But maybe I should have gotten the 1617 ACME 1617 4 Blade 14" x 13.75" Propeller

Those tabs will help you plane out super fast, and will probably help with surfing.

Maybe that 1617 is the cats A$$ but I do question Jeff's data. #1 how is he getting 2500lbs extra ballast? Assuming 750x2=1500 plus bow sac at 650 only gives 2150 and we all know those aren't the actual weights they are less than that. #2 no way that 1579 prop is getting full 750's in rear on plane regardless!


One question though with that int bow sac how much weight do u think u get in? I know after I press the button to fill front starts over flowing well before it times out. I'd estimate I only get about 200lbs of water in the arrow sac. So maybe your getting 400-500(would take more than one button push to fill)in the bow sac which would explain your being able to plane with full rear 750's.

Bottom line before these tabs I had to be very careful with my weighting distribution. To much in the rear and she would not plane or take forever! To much in the nose and the wake lost to much lip. It was always a trade off, plane time vs how much lip u wanted. Now I don't have that issue.

#1 I don't know, maybe he was counting people weight. The integrated bow sack probably gets about 400 lbs in it.
#2 The 1579 WILL get it on plane. I've been using that prop for the last month because my 1617 was getting repaired.

You can question all you want, but I'm giving you my real life experience with the boat. The boat Jeff used for his tests is now MY boat.

I'm glad you like your trim tabs. If they work for you, that's great.

During those tests, I had an extra 350 in the bow walk-thru on top of the rest of the extra weight. These numbers are legit. I tested them early one morning on a smooth lake with no traffic.

[simplysanj]

Wow, that's awesome! Have you tried dropping one tab in a surf configuration? Very curious how that would impact a surf wake as I'm toying with a similar design.

Ok makes more sense now! with the extra 350 and the int bow sac I could see the 1579 getting the boat on plane. In fact before I bought my lead I had to use a extra 300lb bag up in the bow to plane out if I filled the rears to full. Like I've said all that bow weight really kills the lip on the 210 wake.

And simple no I didn't get a chance to try the tabs for surfing yet but will hopefully soon and will report. I'm guessing that they might help lengthen the wave.

I don't use the 350 lb bag in the walk through. I only use the weight as described.

Yes, the more rear weight, the more vert the wake, but my setup still has a great lip.

It sounds like you're trying to get a Old School 210 vert wake out of the boat which the newer 210s are not capable of because they won't get on plane with all the rear weight. Sounds like you may have found a solution.
