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?

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 . . .

Re: prop will not fit different thrust hub washer?

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.

hi there guys let me show this diagram


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...

Re: prop will not fit different thrust hub 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.

Host the pictures on photobucket.com, size them to 640X480, when you open a pic in photobucket look on the right side of the pic and you will see some code links, use the bottom one IMG CODE, left click it then right click, left click copy, come to the thread and right click, left click paste, the link will appear and when you post the pic will be in your post.
