prop change

Joker2 · #1 06-29-2012, 05:44 AM

I purchased a new prop Michigan wheel vortex ,it came with a hub kit, when I went to change the prop, I put it all together and the washer that goes on after the prop ( the one that is about 3/8" thick and has grooves to interlock with the splines ) doesn't catch any splines. The splines end flush with the end of the hub assembly. Did everything the way the instructions aid to do, they reference using the old washer and they show it in the diagram but it looks much thinner ( like a regular washer ) can I go to a marine store to get this washer, without it the prop just slides right off. This is the type of setup i have now. Thanks

I had the same problem. First, be sure to check that the hub is in correctly as there are a few different positions it will fit. Only one is correct. Second, You may need to just put on the thin washer amd bolt and then tighten down to seat the hub. Once you do that, take off the nut and add the inner ribbed washer and then the flat washer and finally the notched high ring that holds nut in place along with cotter pin.

Also you need to make sure you have the correect thrust washer installed. The big heavy washer that goes on the propshaft before the prop goes on is different on the early engines VS the later engines(around 91 they changed over). If you put an early style washer on a late model propshaft it will not allow the prop to go on all the way and your aft washer will not engage the splines properly.

The thrust washer they gave me in the kit is smaller in thickness than the one that was on there, it doesn't matter which position I put the hub on it all sits the same.
