Thrust washer sizes

[stivov1]

I've only used a few different props with my boat, recently bought new props to try, the chopper I got wont fit, need a different size thrust washer, How many different sizes are there? where can I get them?

thanks

[FUJIMO]

Theres a million of them. lol ...Seriously, a lot of "aftermarket" props call for they're own design thrust washers, while sometimes a factory Mercury (or OMC) thrust washer can be substituted. A lot of variables. Thru-hub props, Over the hub exhaust props, different shaft spline lengths, different hub spline lengths, etc., etc... Worst comes to worst, you get them from that particular propeller manufacturer.

If you post the prop number and motors gear case its going on we can perhaps advise you on what thrust washer is required? :cheers:

Hi, here is the prop I just got370233370234
my gear case is from an old 1979 mercury mariner, I have 2 other props for it that both use the same thrust washer, but this one the washer is too big for. i'm probably gonna get a new lower unit eventually, just peacing everything together for now so ready for the boating season. thanks for any help!

Thats an Inline fixed hub Merc chopper that I know. Now these are a bit of an odd duck. Good props just that they have the pressed in rubber hub. You can use a flat thrush washer even a reg one as long as the washer isn't interfiering with the weed cutters and you have enough at the nut end to get the nylock down far enough. heas a pic of guy who used a reg thrush washer and said it was fine. but different gearcase. So shaft length may be different I dont know. http://www.screamandfly.com/attachment.php?attachmentid=115065&d=1158614519

Don't you just make sure that that back side thrust washer fits in the hub to keep the prop from wobbling.
But yet keeps your prop out far enough so it dont scrape on the housing.
Then when you tighten the big nut its tight enough so the prop has no movement before the big nut bottoms out on the shaft shoulder?

[stivov1]

yes i agree! there are some great guys on here! i'm in michigan, not many guys around me into these kinds of boats, so I'm on here for most of my help with things. appreciate all the help! How is canada, lots of speedboaters? i've got realatives in tilbury, we shoot straight accross lake saint clair and visit them in the summer

Yes these small ear Choppers dont have the recessed hub like most and with weed cutters still on need the flat washer. BUT you can get away with the tapered washer with the lip but only if your shaft is long enough for the nylock to bite enough threads. The other end of these hubs protrude also so too thick of washer makes the shaft to short to properly get enough bite on the nut. So yes exactly like ya said but not everyone knows all the types. i had a prop last summer that took a real odd ball washer that i never used before or had. It took some digging to find one. None of my flat ones worked and none of the reg ones. It required whats called a continuity washer 12-31211Q03 Its the only way i had enough room for the nut to fit. This odd duck!! http://cdn3.bigcommerce.com/s-y1epbhg/products/244/images/4441/washer4__77934.1456857113.1280.1280.JPG?c=2
