My Nautique 220 Home made NSS build

[1955 classic]

Andrew put it right, the 220 has a fair bit of distance from the outer bolt when the plate is out due to the curve.
I ended up with m8 bolts thru hull, and m6 holding on slider plates, therefore if i ever hit something, it will be the sliding plate thats damaged as that has the smaller screws.
With any luck ours will be fitted by the end of the weekend
Andrew it only took me 8-9 months
Water testing sunday gonna be cold!!!!!!! 11 degrees celcius water, and 9 degrees celcius air temp is the forecast

Very impressive work you've done here AndrewC. I'm builing the same kind of "surf upgrade" on my ski boat. I will post Pictures as soon I've made some visible progress.

I will use the Standard lenco actuators.

I have question regarding your self made control panel. How do you make sure that the actuators are not drive out to far? As far as I understand, your control panel just gives the Signal (without position indicator and end-stop). Or do you have your actuators just driven out as far as possible and at this position the actuator stops even if you still give Signal. I know that it will stop at the end position , but does this cause any damage?

Hi mate, indicators are not required as all surf systems with run at 0% or 100% deployed. The way trim tab actuators are built, they can hit the end without doing damage. Basically there is a bearing inside that runs in a spiral track and at the end of this track, the spiral stops and just goes round square to the shaft in a continuous fashion. Sorry it's hard to explain!

The main thing to know is the stroke time of your actuator. You just hold the finger for that long or longer to be sure

Most actuators are either 5 or 8 seconds. No need to make and complicated!

Hi, thank you for your answer.

Your explanation helped me a lot. If someone pushes the button too many seconds, nothing will happen.

Makes it a lot easier

Andrew,

would that system you designed work for a 2005, 226 TE. Your design looks awesome!
