Brass hub impeller
Hey guys I got the lower unit separated from the upper (with a lot of oil coming out). Got the impeller housing off without any problems. After prying like crazy and getting a dremel tool to finally cut the old impeller off the shaft. The impeller on the original 470 has a brass hub. Does the replacement have to be a brass hub? The kit I bought at the dealer (after looking up serial #s) doesn't seem like its brass-more of a fiber core. I haven't had a chance to clean the shaft yet so I don't want to force it on - but it seems like the correct ID.

Some are brass and some are a fiber core that is a porous black plastic like material. Either one will work, some prefer the brass and others the fiber core.

Be sure to clean up your input shaft good with some fine emery cloth. Like Ferm said either one should work fine. I usually buy the original replacement kit from the Mercury dealer close to me. Sierra makes a good replacement kit too!!
