2008 Tige 22 Ve' Ran a Ground

[jhooper75]

My first time posting on here but have seen lots of great discussions.

So, last weekend my daughter was wakeboarding (was running approximately 17 MPH) when all of a sudden, we hit a sandbar. No logs, rocks or other debris just solid sand. I shut the boat down immediately. With a 150 ft line and a kind Air Nautique owner we were finally able to free the boat and able to idle back to the dock.

Needless to say, 2 of the 4 blades on the prop were bent; I dont see any obvious damage on the strut or shaft.

I was running the stock ACME 537 prop 13.5x16 so figured it would be a great time to upgrade.

Bought the ACME 1235 14.5x14.25 from Nettle prop in Austin and installed yesterday.

Dropped the boat in the lake and everything seemed fine at first BUT am experiencing significant vibration between 2K and 3K RPM.
I swam under the boat and rocked on the prop back and forth and felt a tiny bit of play in it so was thinking maybe it just needed to be tightened a little bit more.
From everything I have read, it seems more likely that something is either out of alignment OR the strut/shaft is likely bent
OR the boat just doesnt like this prop?

Anyone out there experienced anything similar? I dont know if I am at a point where I have to take it to a shop or what

Terrified of damaging the transmission if i havent already

That boat will absolutely like the 1235, so you've either got more damage or the prop is not fully seated. If the later, you cant seat it by tightening more on the nut. need to remove prop and start over. May need to even lap the prop to the shaft.

Im always suspect of a bent shaft, strut and/or rudder. Id take a closer look.

Thank you for looking at this chpthril. Attempting to add some pictures as I should have in the initial post. Does anything look obviously damaged beyond my comparison of the new prop with the old prop? Praying that all it needs is to be removed and re-tightened with more torque.

best,

Its hard to tell if stut has any bend from that angle. ACME only specs 30 or 35 ft lbs on the prop nit. Shouldnt have to reef it down.

That prop just kissed the bottom. id start with re-seating the new prop.

Thank you both. I took another couple of photos to add to the mix.

I know Acme says 35lbs of torque should be adequate, but then again wondering if my torque wrench is even accurate.

I put some more torque on it yesterday after pulling out of the water but as chpthril was saying probably need to pull it off and start over.

I read that the line you place on the shaft prior to fully seating should be completely covered after torquing down and mine is not.

Please let me know if anyone has any additional thoughts. Sucks when things are not right.

The German method works just fine, gootentite. As long as the prop is fully seated, the nut has a very small job, just keeping the prop in place. The nut can easily reach and exceed the recommended torque yet the prop will never seat all the way on the taper. So dont stress over the torque value.
