    Will the prop nut go on, but you can't get it low enough to get the cotter pin in? Is the prop getting onto the washer down on the outer ring? Or hanging up on the pilot "shelf"? Picture?

          first pic that show the prop and the prop hardware the piece (F) thrust hub if i use the same then the piece (C) and the (A) will not have any space to tie the nut So what im thinking is if they make a thrust hub piece (F) in diferents thickness?. thanks.

            Sometimes C is cast into the prop. Possible?

                Do any of the threads extend to where you could get a thin nut on it? I had to run a very thin nut on my torque shift . . .

                    that is strange. If you're near a dealer, you might take pics and stop by the parts counter.

                    I will try to remember to look at mine tonight. I have both a solas prop and an alpha drive (one drive on the boat, and another with no prop on it in the kitchen). I do seem to recall having to swap washers around to get the solas to fit the way i wanted it to, but had whatever I needed on hand. It was last year so I don't remember off the top. I'll share what I have if noone else posts an answer.

                        (F) in diferents thickness.

                        Yes. What's the thickness of your existing Thrust Washer/Hub?

                        I just replaced my Prop. I had the same problem. The thickness of my Hub was ~7/8 inch. Apparently these were changed years ago. I purchase one about half the thikcness for $27 and it worked out pefectly.

                        If your stuck call Petzold's Ship Store. Phone# 860-342-1196

                        Describe what you have and they can probably help you out.

                          Sounds like if you stop by the local merc dealer thay'll have the right one. I just checked and my titan 4 fits just right with the thinner washer...

                              Take a look at this iboats page about 3/4 of the page down it shows the 318841 as an OMC part number . . . The Merc one is a 12-835467, I have one on my desk and it measures a total thickness of 3/8 and the pilot "shelf" reduces the working thickness to 3/16 . . .

                              PM me, I have few of these if you want one . . . Even one that is worn a little thinner.
