SN 200 Rudder 2015 - Bolt torque?

[FMSKI]

My 200 slalom wake woes, we traced to the improperly tuned rudder. The tabs were full over.
The rudder was VERY loose, so my buddy tightened the top bolt and that corrected the issue. The tiller arm has this crazy damper weight on it, looks to be aggravating the issue.

Anyone know what is the torque spec on that bolt? Why it could be backing off /other issues (it is wired up as well).

PS This is embarrassing - was showing the boat our FM manager, stopped at a bay to check the rudder/swim. Left the stereo on. Swam more than expected to an island and back. Left the boat floating. Came back wouldn't start Voltage was at 11.5 so I thought the battery was pooched. Texted my son, he brought out the L Ion booster. Still wouldn't fire. DANG - the shift lever is really stealth, it was slightly forward, tripped NSS. That is the 3rd time I've error-ed out on that shift lever. The knob is sloped and the background is visually confusing..

Not sure exactly what the torque should be, but if the stainless wire was in place, I don't see how it could have backed off that much.

Make sure that wire is there. You DON'T want to drop a rudder. If you do, the boat will sink!

Thanks for the warning!. Yes the blade will just drop right out, so I'll be careful. The bolt did back off a little again today. Problem is when the bolt is not super snug, the rudder gets sloppy side-side and causes the 200 to hesitate, then grab in turns.

Since I have a bow tank on the 97 boat, I can see the rudder ***'y plain as day. The top bolt is very tight - I'm guessing ~40 ft-lbs, but since it's got the wire I can't move it much anyway.

The fastening setup reminds me of a bike handle bar stem assy. There you set your bearing pre-load with the TOP bolt, then tighten the pinch bolt. I'm thinking it's the same here, torque top bolt, then do tiller pinch bolt??

I googled and can't find the info. There are some pretty cool rudder setups tho. The ones used by SN are basic.
