I think the outboard has no real contact with the turboswing and the bolts used for mounting.
You can pull a lorry through the water. maybe theyre not that strong sideways but still then you can hang a car (hummer) on it. So i think no whorrys there.
I'd suggest the force or leverage would be lower as the towing point is lower to the angle of the fixing bolts instead of the d ring on the top of the A frame for example.
We all know the longer the distance from fixing to top the more strain on the actual fixing when being towed from. Hence why the longer the wheel wrench etc the easier to use.
I don't see any problems with it based on correct fitting. Like others have said I've never seen an outboard drop off so why would that suddenly change as the same force/weight is being pulled as before just from a different positioned frame.
I would have thought the force on the mounting bolts is tiny for a boat pulling a skiier compared to, say, a boat full of 7 people all with dive kit being shoved along by an outboard.
I just used my turboswing for the first time this past Saturday. I purchased it last summer after reading about it here and getting a good deal on a used one here in the States. I have a Caribe inflatable and the tow eyes were so low on the transom that the tow rope would get hung up in the wake slow the tube down on the turns, it made it really hard to dump the kids off.
It didn't rip my transom off on day one so thats a good start. I can say the construction of the brackets is very impressive. The hoop is just tubing but brackets are very substantial.
I have had one on a caribe C20 RIB, 90 HP Honda for two summers. It helped me a bunch because the transom is so low the tow rope dragged through the water and would slow the tube down too much. With the turbo swing it's much easier to dump the kids now :-)
I also found mine second hand but new so I paid much less for it. The brackets are probably 10lbs each, they are very beefy. I have not had any trouble with mine except I got the pole too close to the engine and the hook carriage hit the cowling and scrapped it up.
