The bearing cups for mine don’t seem to match what is supposed to be in there. I purchased my boat from a marine mechanic so I’m guessing he swapped out the gear set at some point, which is why I worry about using oem part numbers for sourcing parts (although that double lipped seal didn’t seem...
Well that would explain a lot. This is the kit I got:

Anyone have a part number for the proper seal?
0L726551. The seal I installed looks different than the one I took out, although the one I took out was so corroded and shredded it was hard to tell what was the seal and what was the aluminum. I had to use a wire brush and a magnet to find the edge it was so corroded. This pics are of the...
Just the yoke passing through the seal with nothing else assembled provides enough resistance to be beyond 5in/lbs. I took pics at disassembly, it really comes down to the yoke and the seal being a tight fit. Maybe I need a different seal?
Yes all greased per manual. The entire assembly spins on top of the retainer nut without the bearings even spinning. If I hold the bearing cups still the reading is like 8in/lbs with the nut just finger tight.
Unfortunately the nearest boat mechanic that will work on I/Os is hundreds of miles...
The bearing will be flat if you drive it in all the way. You will need to align the engine using the front engine mount. My adjustment nut was seized on and I had to cut it off. In order to reach the nut I had to remove the rear seats and panel in front of the engine. Don’t force the alignment...
I just replaced my oil seal and replaced my yoke and now I have it all together and I’m attempting to set the bearing preload. The issue I’m having is that the friction between the new seal and the new yoke alone is significantly greater than 5in/lbs. How am I supposed to get an accurate reading...
