I figure I will start a new topic on this. Where i started it it had nothing to do with this.<br /><br /><br />I ordered a impeller rebuild kit from iboats part#18-3507. For a 64 mercury. 50hp<br />I noticed 2 things when i went to put it together. 1. The new impeller top is made of hard plastic and not metal like the old one, 2. The new impeller cover does not have a rubber seal in the whole where it slides down the shaft for a tight fit like the old one had. Is this suppost to be that way or did i not get something with the kit. Everything else semms to be ok. I would like to get this togehter and put it in the water. any help would be great. Thanks<br />Mike
