When Freshtrax got my 8 hp Nissan running last year we noticed it wasn't peeing out particularly strong. Have the day off work today so thought I would see if I could figure out how to change impeller. After a couple youtube videos I was feeling pretty good to tackle the job. Got the whole thing taken apart...noticed the impeller was in really good shape so ended up putting it all back together again. I had not actually bought a replacement impeller yet...today was actually going to be "Can I even take it apart" day. Since everything looked good, I decided to put it all back together. Anyways, when I got it all put back together, I noticed one of those tiny red seals on the floor...you know, the type you encounter when changing oil in lower unit. Having said this, I did change the lower unit oil in the same spot last fall. So...anyone know if that seal has just sat there since last fall? Or are there seals like this that one would encounter when working on an impeller? I didn't see any red seals during this process, so reluctant to pull the whole thing apart again! But also got a sick feeling that that red seal needs to get back where it belongs.
