Over the years ('94 Cat) in changing the impeller two of the three holes holding the front on have become stripped.  The yard drilled holes all the way through so that machine screws from the front and rear bolts hold the cover on.  This was supposed to be a temporary solution many years ago but seems to be working.  This  weekend, however, I fried my impeller by not opening the thru hull.  Temporarily I replace the impeller with a spare used one and a used paper gasket.  Water seem to be pumping fine, but there is a slight drip around the front seal.  I will be buying a new impeller kit.  I may also have the paper gasket in the wrong place.  Does it go in front or behind the backing plate that is behind the impeller?  My memory is failing me.  Looking for comments.  Thanks.
